2019 USACI SPL RULES

This section of the USACI rulebook was written by the USACI Rules & Ethics committee in order to retain the basic ideas that have always made auto sound competition fun and fair. Each year, USACI forms a committee of members to gain input from its competitors, the goal being to make the contests fair, fun and challenging. This Rulebook and any subsequent refinements are the result of those meetings. It is USACI’s sincerest hope that these rules will be received as an example of the organization’s continuing efforts to promote the competitor’s responsibility to know and adhere to the rules contained herein.

USACI reserves the right to make written amendments to this Rulebook without prior written notification to its members. USACI will, however, make every effort to notify active members via the Internet and/or by distributing any written changes during the registration process of a sanctioned USACI contest. All competitors and enthusiasts are encouraged to visit our website at www.usaciworldwide.org for rule updates, event schedules and event results.

The rules set forth in this section of the Rulebook shall be used by the USACI official(s) and/or judging staff at all USACI Sanctioned events. It is the responsibility of event officials and staff to adhere to these rules to the best of their ability. In consideration of that, each competitor should read this manual and have a thorough understanding of its contents when designing or improving a competition mobile audio system. Ultimately, it is the competitors’ responsibility to know and abide by the USACI rules.

Best regards,

USACI

USACI NATIONAL RECORDS & WORLD RECORD RULES

All rules of the class being run will apply. Refer to the rules and matrix for the division and class in which you are attempting a record for those individual rules and limitations.

National Records may only be attempted at National Record events. If National Record attempts are allowed, the event schedule will denote that with the “NR” in the events category. All National Records recorded at the event must be submitted in writing along with the competitor’s name and individual national record fees to the USACI office within 72 hours of event completion. Once National Records are verified they will be posted and the competitor mailed an award plaque with his/her name, class, new record, and date set. (USA only) Other countries are responsible for their own awards. The Price for a National Record run is $75 in the USA, other countries will set their own pricing structure and are responsible for providing their own awards.

World Records may only be attempted at WORLD FINALS. Once World Records are verified they will be posted and the competitor mailed an award plaque with his/her name, class, new record, and date set.

All vehicles must make two runs, and both runs must exceed the prior record in order for a new record to be recognized. Of these two runs only the LOWEST reading of the two shall be recognized as the new record.

Bracing Teams will be permitted during Outlaw SPL Record Runs. Bracing teams will only be allowed in and out of the lanes as directed by the Judge.

NO Bracing Teams will be allowed in Legal SPL Record Runs.

After a record has been achieved the judge will inspect the vehicle. The engine compartment, interior compartment, trunk or hatch compartment, and undercarriage of the vehicle will be inspected to make sure all the requirements of the class in which the record is being attempted are fulfilled and that there are no modifications that disqualify the run. Only after this verification may a National/World Record be announced.

If a competitor is disqualified on a National/World Record attempt, all previous SPL runs at that event in that class will be given a zero score. Any additional classes the competitor may have run will be subject to a zero score if the infraction applies to more than one division or class. The competitor may purchase a rerun to gain a qualifying score to continue in the class at the event.

If more than one competitor sets a record in the same class, on the same day, or at the same event, only the higher record will be acknowledged.

“LEGAL” records will be recorded on the windshield 12” from the passenger “A” pillar, 4” above the dash, and 1” off the glass. A USACI microphone jig or tape measure may be used to determine this location. The microphone will adhere to the windshield using the factory suction cups provided. If the mic/sensor falls, the suction cups may be taped to the glass but the mic/sensor may not be taped in any way. Vehicle must be closed and sealed. Competitor may be in the vehicle but must sit on the opposite side of the microphone and must wear hearing protection at all times. Competitor refers to registered owner or other persons as designated by registered owner. Podiums will be allowed in all classes expect the Novice Division.

In all Legal (Dash) record attempts the vehicle may be running. The record reading will be taken with the engine on or off, (both runs must be the same way) over a 30 second period. If the first attempt is successful at breaking the record, then the vehicle will be left unchanged and without any work or modifications for up to three minutes. The second run may be attempted in less than three minutes but may not exceed three minutes. Once the second run is complete and both runs have surpassed the current holding record the vehicle will be opened for inspection by the judge. Once the vehicle has been inspected and verified for the class a record will be announced.

“OUTLAW” records may be recorded anywhere forward of the “B” pillar. The microphone must be secured in a USACI certified globe and be placed where it can be observed by the world record official during the entire run. Doors may be open or closed but may not be opened and then closed during the run. Competitor may be in the vehicle but must sit on the opposite side of the microphone and must wear hearing protection at all times. Competitor refers to registered owner or other persons as designated by owner. Podiums will be allowed in all classes except the Novice Division.

In all Outlaw SPL record attempts the vehicle may be started 30 seconds prior to the record run. Idle must be set no more than 2000rpm. If a record is achieved on the first run the vehicle may not be worked on or modified for a period of up to three minutes. You may elect to do the second run earlier but no later than three minutes after the conclusion of the first run. If the record attempt is successful then the vehicle engine will be turned off and the vehicle opened to the judge for final inspection prior to record being recognized.

USACI SPL GUIDELINES

DIVISIONS:

Outlaw SPL divisions are based on the configuration of the system and vehicle. Specific guidelines for each division will be discussed in their respective sections of this book

CLAMPED CLASSES:

You will be required to have the amplifier(s) and speaker’s wires easy to access and verify that the clamp meter is connected properly and no rules are violated.

The subwoofer amplifier(s) is/are limited to one set of speaker wires (a single + positive wire and a single – negative wire) out of the amp at least 1ft in length where the clamp and probes will be connected to ensure the power will read properly. After the 1ft of length out of the amplifier(s) you can split the speaker’s wires as many times as you like to the subwoofers.

The speaker wires should be a minimum of 12 gauge in size to properly probe the wires.

In the case of two amplifiers it is required to have the amplifiers strapped. More than one non-strapped amplifier will NOT be allowed in Clamped Classes.

It is the competitor’s responsibility to possess the tools and skill to connect/disconnect the clamp meter. You will be required to clamp the positive speaker wire of the amplifier(s) as well as probe the positive + and negative - speaker wires. USACI and its directors are only responsible for verifying the clamp and probes are connected correctly. USACI and its directors are not responsible for any damage to the vehicle or audio equipment due to improper installation of the clamp meter; the competitor assumes all responsibility of the clamp meter installation and removal.

In Clamped Classes if you exceed maximum wattage your run will be disqualified. You may buy a rerun, but may not switch to another Clamped Class or Unlimited Class in that division, with the exception of the Novice Division.

In order to place in a Clamped Class and get points you must establish a score within the power rating of the class.

Any competitor caught cheating or attempting to cheat the clamp meter will be banned from all USACI events for a minimum of one year.

If any amp gives a false reading after two attempts, the competitor will be moved to the unlimited class in that division, unless it is determined to be a malfunction due to the TermLab equipment.

**USACI reserves the right to review and/or remove any amplifier from competition for the clamped division if we feel it has an unfair advantage or the amplifier will not read properly on the clamp meter. **

AMPLIFIERS DEFINED:

One amplifier is considered one power supply, one system board, driving 1 or 2 channels. A 3-4-channel amp would be considered two amplifiers. A 5-6-channel amp would be considered three amps and so on.

A car audio system’s total wattage shall be determined by the amplifier(s) highest manufacturer published 1 ohm RMS power rating @ 14.4 volts or lower. If the amplifiers rating is higher than 1ohm the power rating will be multiplied to derive a 1 ohm rating. (Example, the amplifier is rated 1000 watts @ 2ohm. 1000x2 = 2000 watts @ 1ohm. An amplifier is rated 500 watts @ 4ohm. 500x4= 2000 watts @ 1ohm) If any amplifiers 1ohm rating cannot be determined, that amplifier will be moved to the highest power class in that division until a power rating can be determined. USACI reserves the right to independently test any amplifier to determine the true 1ohm RMS power rating and reclassify that amplifier as needed. USACI reserves the right to independently test any amplifier to determine the true RMS power rating and reclassify that amplifier as needed.

6

POWER SOURCE:

All audio equipment must derive its power from inside the vehicle. No external power sources (battery chargers, solar panels etc.) will be allowed in the lanes during the run, unless it is determined to be inoperable by the Head Judge.

USACI OUTLAW SPL JUDGES:

Outlaw SPL Judges shall be appointed by the Head Judge or the event sponsors and are subject to approval by USACI. A USACI Outlaw SPL Judge shall not be allowed to judge any vehicle being entered by an immediate family member, employee, employer or substantial customer. The Head Judge may appoint an alternate to judge that vehicle. It is within the Head Judge’s or other USACI Outlaw SPL official’s authority to decide the application of this rule to any disputes.

JUDGING ORDER:

The Head Judge will determine if there is a specific judging order. Judging will end when all vehicles have been judged. No score or refund will be given to a competitor who fails to have their vehicle in the judging line before the judging has ended.

“3 MINUTE RULE”

Any competitor who allows or causes more than a 3-minute “gap” between cars at the judging station may have their score disqualified and have to make a rerun, at the discretion of the event director.

USACI reserves the right to run an event using either an in-place or specific order judging routine. At any event, it is the responsibility of the Event Coordinator or Head Judge to inform the competitors involved of the details of that day’s judging format.

MULTIPLE JUDGING LANES:

Some events may form two or more judging lines in order to expedite the judging process. In such cases all competitors in a particular power class and division will be judged in the same line and on the same test equipment. It is the responsibility of the competitor to confirm which lane his or her power class and division is to be judged in.

DRIVING THE VEHICLE THROUGH:

Judging shall be conducted with each competitor’s vehicle being driven through a judging line in an orderly fashion. The vehicle must drive in and out of the judging lane under its own power.

SYSTEM OR VEHICLE MALFUNCTIONS:

An equipment or vehicle malfunction is the competitor’s responsibility. Once the vehicle is in position to be judged, the competitor shall be allowed a maximum of three minutes to correct or repair any malfunction. After the allotted time has expired, the vehicle must be judged if possible or given a score of zero. No repairs will be allowed after SPL testing has started. No refunds will be given.

RERUNS:

At most events competitors will be allowed to register and rerun their vehicle to improve their score or standing. If a competitor chooses to rerun his or her vehicle, the sound system must be made up of the same size speakers, the same number of speakers, and the same number of amplifiers as was in the vehicle on its first SPL attempt. A change in brand is acceptable provided the new equipment does not change the class or division of the vehicle. There will be an additional fee for all reruns. All competitors must have an operational system in their vehicle at the time of registration. This system must be the system the competitor competes with at the event. Competitors may change equipment in case of malfunction, but entire system and enclosure may not be swapped.

Intent: The intent of this rule is to prevent competitors from sharing the same audio system in more than one vehicle. The Head Judge at the event shall interpret this rule and such decision may only be appealed to the USACI rules and ethics committee.

IN CASE OF A TIE:

In the event that two or more competitors in the same Clamped Class receive the same final score, the winner will be determined by lowest wattage established.

Novice and Unlimited classes will continue to do tie breaker runs until the loudest score determines a winner.

7

DISRUPTING AN EVENT:

The Head Judge reserves the right to deduct points or ask any competitor to leave an event if the competitor’s behavior becomes disruptive during the course of the event. If a disruptive competitor is asked to leave, the competitor will not receive a refund. Any points or awards the competitor might have earned at that event will be forfeited. Competitors will be responsible for the actions of their guests at the event.

If the cause of the inappropriate behavior is believed to be alcohol or any other controlled substance, USACI has the right to ban the competitor from competing in any sanctioned USACI events for a minimum of one year.

To help assure that every USACI event is conducted in a safe environment, no weapons in the possession of a competitor or anyone accompanying a competitor will be tolerated. If the competitor does not comply with this demand, he or she will be disqualified, asked to leave the event site or be escorted from the site by the local authorities. Any threats towards anyone involving a weapon, however casual, will be cause for banning the competitor from ever again competing in any USACI sanctioned event. No refunds will be given for being disqualified.

CHEATING:

1st offense = 1 year

2nd offense = 2 years

3rd offense = Banned for life

APPEALING A DECISION:

If a competitor questions his or her score or a possible error in the judging process by which that score was achieved, the competitor may seek explanation by the Head Judge of the event. The decision of the Head Judge will be considered final at that event. After the event, a competitor may petition the USACI Rules & Ethics Committee to reconsider either a rule or a Head Judge’s decision. Neither USACI nor an event sponsor assumes responsibility for any awards previously given to another competitor, even if in error.

PROTESTS:

If a competitor has made a plausible complaint, involving any unfair or illegal item which may be hidden in another competitor’s vehicle, and would require disassembly of that vehicle or audio system to verify its existence, then the complaint must be accompanied by a cash security deposit. (No checks) Such complaints may only be made after the vehicle in question has been judged at that event and before any prizes are awarded. The security deposit required to file a protest at a Single or Double Point event would be $250. Triple points, Regional, and finals events will be $500.

The Head Judge must have the security deposit in hand before any action may be taken. The Head Judge or their representative will then oversee the disassembly of the vehicle in question. The competitor whose vehicle is in question may elect not to have their vehicle inspected by disqualifying themselves from the event with no refund. If, in the Head Judge’s opinion, the vehicle in question is found to be inconsistent with this rule book, the cash security deposit will be returned to the competitor making the complaint, minus a processing fee of $100, and the competitor in question may be disqualified from that event and all future USACI events depending on if it’s the 1st, 2nd, or 3rd offense. The competitor can correct the offense and purchase a rerun to gain a qualifying score to continue in the class at that event. If in the Head Judge’s opinion, no inconsistency is found in the vehicle in question, then the cash security deposit, less $100 USACI processing fee, will be awarded to the competitor whose vehicle was inspected and it will be the responsibility of the competitor who was protested to reassemble the vehicle or audio system.

In the event a competitor is protested, they must be present to be verified otherwise their runs for the class in question will be disqualified. Protests may be made anytime before the lanes close.

RULE INFRACTIONS:

Any rule infraction that can be resolved WITHOUT disassembly may be handled by the Head Judge at the event when it is brought to their attention. If a Rule infraction is brought to the attention of the Head Judge during a run, the Judge may call for corrective action before the competitor will be allowed their second attempt. If the Rule Infraction cannot be corrected or the competitor refuses to correct it, the run must be reclassified or disqualified. These infractions must be brought to the Head Judge’s attention before the lanes close.

All Rule Infractions should be brought to the Head Judge’s attention in a calm and respectful manner.

8

SOUND PRESSURE LEVEL TESTING:

The occupant of the vehicle under test shall have proper hearing protection if remaining in the vehicle for testing. If occupant does not wear hearing protection they assume all liability for damages. Only the registered owner or person of their choice may be inside the vehicle during SPL testing.

The SPL microphone/sensor may not be placed on the same side of the vehicle as the competitor. Competitor testing inside their vehicle must remain in the front of vehicle (forward of “B” post) during their run.

An audio system’s Sound Pressure Level will be measured using an approved sound pressure level meter. This test must be measured using the current version of the USACI Outlaw SPL competition software, unless stated otherwise in a specific division. A CD, USB, IPOD etc. may be used as long as the judge can verify the software’s authenticity. The director of the USACI event will provide this in the case that the competitor does not have their own.

The Judge will be responsible for making sure the SPL meter is set up and functioning correctly. The competitor must have the vehicle ready to test prior to entering the judging lane. After the SPL microphone/sensor has been placed, the software loaded, hearing protection properly placed over the occupant’s ears (if applicable) and the system readied, the competitor should signal the judge that he or she is ready for the test.

Once the test begins the competitor has thirty seconds for all runs, except Bass Battles Division which allows for 60 seconds, to try and achieve the highest score possible. The music, tone or sweep may be restarted and/or the tracks can be changed as often as possible within the allotted time. The competitor may choose to stop the SPL testing at any time before the end of the allotted time, but the judge must be able to verify that the correct software is being used during testing. The use of tone generators, doublers or any other device that externally (outside of the closed signal chain) generates or alters the frequencies that the system is playing during SPL testing is expressly prohibited and will result in disqualification with no refund. Any tampering with the microphone/sensor or attempt to create a measurement by any means other than SPL produced by the audio system will be considered grounds for immediate disqualification and possibly being banned from future competition in any sanctioned events. The Head USACI Official present will investigate for any evidence of such tampering and the ruling of this official is final.

MICROPHONE/SENSOR PLACEMENT:

The microphone/sensor will be placed anywhere forward of the “B” pillar in the passenger compartment with a microphone/sensor globe attached in all SPL classes. Special panels or enclosures for globe placement will not be allowed. No objects will be allowed to cover the globe, including but not limited to floor mats, carpet, towels etc. No objects will be allowed in the seats or floorboards forward of the “B” pillar. The microphone or sensor may not be placed anywhere that is deemed “hazardous to the equipment” by the Head Judge. The Microphone may be removed from the globe during testing only of it is to be placed in the “LEGAL” position on the windshield. Legal Position is 12 inches from passenger “A” pillar, 4 inches above the dash, attached to the windshield. Any construction or speaker placement that may manipulate the SPL meter may be considered reason to reclassify the vehicle. This decision will be at the discretion of the Head Judge. All lanes will use the same individual globe and mic/sensor throughout the event unless there is a malfunction of the globe or mic/sensor, then the judge may replace the globe or mic/sensor and continue the event. The globe and mic/sensor will be used in the same manner by all competitors and may not be attached to the vehicle in anyway other than the jig that is optionally provided by the judge. Competitor-owned mic/sensors, globes, jigs and clamps are not allowed for use during testing.

RESPONSIBILITY OF COMPETITOR:

It is the competitor’s responsibility to fill out the event entry form with their first and last name or team name (must be 2 words), that it is written legibly, and are also encouraged to ensure against spelling and class selection errors in order to ensure accurate standings and points accumulation.

The competitor is responsible for his or her vehicle and audio system and any physical or mechanical damage resulting from their use or misuse of the vehicle and/or the audio system therein. It is the competitor’s responsibility to know and abide by the rules contained in this book. If a competitor has questionable modifications or factory options, the competitor must supply the proof that it is legal for the class in question. It is the competitor’s responsibility to know and understand how the clamping process works. See attached diagram on Page 11.

DEFINING THE TERM “COMPETITOR”:

The term “competitor” applies to the vehicle’s owner or team, an employee of its owner, an immediate family member, or a person bearing a power of attorney for the vehicle’s owner. If a competitor is unable to attend an event, he or she may designate someone to drive the vehicle through the judging line. The designated person will be considered a competitor and will assume all responsibilities of such. Only one vehicle will be allowed to compete under one unique competitor name per event. No one vehicle may be shared by multiple competitors at any given event, and must be run under the name of the owner of the vehicle.

9

EVENT REGISTRATION:

Event registration will begins at the stated commencement time of the event.

Each vehicle can be entered and judged in only one class but in as many divisions as it may qualify to compete in, with the exception of Novice Division. A separate registration is required for each division’s judging. No matter the number of vehicles one competitor is running, they may only enter one class per division. Vehicles may reenter the same class as many times as the event schedule will allow. (Reruns)

All vehicles must be licensed and registered, and be “street legal” as per federal regulations to compete in the, Novice, Stock and Trunk divisions (Or any class/division that uses these rules). Vehicles that do not comply will be reclassified to another division.

It’s the competitor’s responsibility to maintain proof of financial responsibility.

VERIFICATION JUDGING CRITERIA:

The verification judge will verify the power ratings of each amplifier installed (if applicable) in the competitor’s vehicle to ensure that the vehicle has been entered in the appropriate power class. The verification judge may install a voltage meter in any vehicle IN ANY DIVISION to monitor voltage during the run. While this is optional at single point events it will be MANDATORY at all multi-point events. If a competitor’s audio system does not, in the judge’s opinion, meet all of the following basic requirements, the competitor may be disqualified from the event or be reclassified to the Unlimited Class. The vehicle and audio system must be fundamentally safe for the judging area. The audio system must consist of components that use some form of 12 VDC negative ground power supply. The vehicle and audio system must operate under its own power while being judged. No equipment (batteries, subwoofers, amplifiers etc.) can be changed after the vehicle has been verified for a specific class until the vehicle has left the judging lane.

During verification only 1 person with the vehicle may be present.

During any run, only people associated with that vehicle will be allowed in the lanes. Everyone else will be required to be behind the barricades. The competition lane must remain free and clear of spectators and/or excessive persons, as deemed by USACi staff.

The Head Judge at the event has the final judgment regarding any required rulings at said event.

QUALIFYING FOR USACI WORLD FINALS:

Special Invites will only be given in the case of Acts of God, Major Life Events, or Military Deployment.

MILEAGE CURVE:

Competitors with no shows within a 200-mile radius (Mileage Curve) of their permanent residence during the competition season will automatically be qualified to attend World Finals. Competitors attending World Finals under the Mileage Curve will only be allowed to compete in one class and will be subject to an additional $100 processing fee.

Show Attendance Percentage:

Any Competitor that has a LIMITED amount of shows within a 200 Mile Radius of their permanent residence may qualify for the Show Attendance Percentage, and may compete in any classes for which they have accumulated 25 qualifying points or more.

If a competitor has 3 or less shows in their area and meets the show attendance % but not the qualifying points for any classes, they may be permitted to run whichever one class they have accumulated the most points in.

Show Attendance % is as follows:

50%-74% will be eligible and only pay an additional $50 fee

75%-90% will be eligible and only pay an additional $25 fee

91%-100% will be eligible and able to come without the additional fee.

*Show Attendance Calculation Formula: (X/Z=A)100 (X = # of shows attended, Z = # of shows offered, A =

Attendance Factor. Example: 5 Shows attended / 6 total shows = .83 multiplied by 100 = 83%. For questions regarding this calculation please email usacilindsey@gmail.com

A competitor may only compete in one class per division, but may compete in multiple divisions if the competitor is qualified to do so.

Qualifying Runs will be on Saturday, if you have not been given a time slot for that day or turned in your entry form in the lanes you will not be permitted to Rerun on Sunday.

TOTAL POINTS REQUIRED FOR USACI WORLD FINALS =75

POINTS REQUIRED PER CLASS FOR USACI WORLD FINALS=25

POINTS CUTOFF WILL ALWAYS BE THE 1ST SUNDAY OF SEPTEMBER, ANY SHOWS AFTER THIS DATE WILL BE POINTS ACCUMULATED FOR THE FOLLOWING SEASON.

2019 Points cutoff is September 1st.

On vehicles with removable or convertible roofs, walls or panels, all equipment and all parts of the enclosure must remain inside the passenger area and may not protrude into or be located in an open air bed or other storage area not covered by the same roof that covers the passenger area.

Vehicle bracing teams are allowed except during legal runs. You may sit on the vehicle. The owner of the vehicle assumes all liability and takes full responsibility for anyone that is bracing, or on top of the vehicle. Absolutely no one under the age of 18 will be allowed to brace or be on top of the vehicle, this will be the responsibility of the owner of the vehicle.

Commercial type vehicles such as box trucks, panel trucks, anything bigger than a full size van or truck, buses, ambulance, armored car/truck, 18-wheelers, etc. will only be allowed to compete in the Xtreme classes.

Competitors will not be allowed to compete using another competitor’s vehicle to enter classes.

In the case that someone is running a vehicle for another Competitor they must run the vehicle under the vehicle owner’s name.

13

A vehicle may only be run under one name per event.

If a competitor’s SPL run(s) are disqualified due to a rule infraction, the competitor will receive a zero score. The competitor will be allowed to fix the issue and purchase a Rerun only if the infraction is deemed unintentional by the head judge. Disqualifications are for the runs, not the competitor, unless it is deemed intentional, then the competitor will be disqualified.

Any competitor that is caught intentionally cheating will be banned from USACI. The length of the ban will be determined by the Rules & Ethics committee based on the severity of the infraction.

If any vehicle experiences a window break during testing at any event, the competitor will be allowed to use up to 2 layers of clear packing tape to help keep the vehicle safe for any additional runs, so long as there is an 8.5” by 11” horizontal viewing window on the driver’s side left un-taped.

Competitors must be present at a show to acquire points. Competitors who have entered an event, present and able to be verified, will receive a score of 1 if the event is shut down due to unforeseeable issues at the show. (Venue shuts down, Law Enforcement shut down, or Severe Weather) Competitors who receive a score of 1 will not receive an award. This is NOT for Competitors that ran in their division and exceeded their power rating for the class entered or competitors that entered a clamped class, you must put forth a score in a clamped class without exceeding the wattage limit to acquire points.

USACi Competitors registered or pre-registered must have their entry forms turned in at the USACi Booth to qualify for any score/points. Under no circumstances are refunds issued for on-site entries or pre-registered entries. USACi entries are non-transferable at any event.

NOVICE DIVISION

These Rules go into effect November 8, 2018. If a competitor that qualifies as Novice is planning to run this Division but have run other divisions prior to November 8, 2018 the competitor may still run in this Division so long as they stay within the qualifying classes for the remainder of the season.

The novice division is intended for an entry-level competitor to compete on a national level.

Any competitor that wins or has won 1st place, in the Novice Division at USACi World Finals, or obtains / has obtained a World Record in the Novice Division will not be allowed to compete in the Novice Division any further.

Any competitor that had placed 1st, 2nd or 3rd, at USACi World Finals in the other divisions for the 2018 season will not qualify for Novice Division, as well as any competitor that has ever worked in the 12v industry either on a retail level or a manufacturer level will not be allowed to compete in the novice division.

When running in Novice Division the competitor may not enter any other USACi Sanctioned Classes except Port Wars. However, competitors will be allowed to run any local / non-sanctioned classes that the promoter has available at the shows.

A Competitor may not use a vehicle that is used in another class under a different name at any given event.

Competitors in the Novice Division may be allowed to compete in 10 USACi Sanctioned Events before no longer qualifying for the Novice Division. If a Novice competitor reaches their overall limit of 10 Novice events, during any one given season, the competitor will qualify to compete at World Finals for that last season, so long as they do not compete in any other classes or divisions throughout the remainder of that show season, with the exception of port wars, and local/non sanctioned classes.

If a competitor that has reached their novice limit of 10 shows chooses to compete in any other sanctioned classes or divisions throughout the remainder of that show season they will not be eligible to compete in the novice division at World Finals, but may compete in any other classes or divisions for which they qualify.

Competitors still under their 10 show mark will not be penalized for running a different class during the 2018 season, so long as they were a Novice in the Novice Division and meet all the other qualifying requirements for this specified Division.

Super capacitors will not be allowed.

Novice Division will be clamped. In the event a competitor in one of the Novice Clamped Classes exceeds their maximum allotted wattage they will be bumped to the next class they qualify for in the Novice Division.

Any violation of Novice rules found at any given point in the season will result in a DQ and a deduction of points, and may also result in the competitor being permanently disqualification from competing in the Novice division.

BASS BATTLES DIVISION

The power source may not produce more than 18.0 volts, at any time during the run, with or without the vehicle running. Modifications will be allowed to the interior of the vehicle behind the B-pillar

The floor of the vehicle may be cut behind the B-pillar to accommodate the sound system

The competitor will choose their own music. There will be no solid tones, note must change, the judge will make the final call, and if your run is deemed illegal you will receive a zero score, and must choose a new song for your 2nd run.

Audible highs/midrange music must be able to be heard from outside the vehicle. Scores will be determined by an average SPL taken over 60 seconds.

The Sensor placement will be any place in front of the B-pillar with globe affixed or mounted to windshield without globe at 12” to the left of passenger’s side A-pillar and 4” above the dash. (Competitor’s choice)

Aftermarket windshields made with materials such as Lexan, Plexiglas, polycarbonate, etc. will be allowed. These windshields must resemble an OEM windshield in appearance and function, and must use the factory mounting location. A maximum of two layers of OEM or equivalent DOT approved windshields will be allowed

A single floor to ceiling brace (stripper pole) will be allowed, no more than 2” thick at any given point, it must be in the center of the vehicle or very close. The mounting plate can be no more than 3” wide and no more than ½” inch-thick at any point. The front brace may extend all the way across the front windshield. If the brace is behind the B-pillar, it must be removable and not affect the string test.

OEM interior panels may be upholstered or painted, but may not be modified or removed in any way but with these exceptions:

The OEM dashboard may be modified to accommodate the sound system. Only the portions of the dashboard housing electronic components will be allowed to be modified.

Custom consoles and door panels are allowed. These modifications should serve a purpose in appearance and functionality. Custom consoles and door panels may not be oversized for the vehicle and must be used to accommodate the sound system.

Seats are not required in Bass Battles Xtreme ~ Xtreme and commercial vehicles may compete in Bass Battles Xtreme only

Scoring for Bass Battles

We will take your peak frequency according to TermLab and your score and you will receive bonus points based on 80hz cap limit which will add up to a Composite SPL Score.

The bottom frequency cap is 20HZ, so if you peak at 19 HZ you will still only be allowed the max of 60 bonus points

We will take your max frequency at the peak score and then subtract that from 80HZ that will be your bonus points added to your score. If you hit 150 @ 30 HZ, you will get 50 points / 150 @ 20 HZ you would get 60 points 150 @ 40 HZ = 40 points and so on.

TRUNK DIVISION

TRUNK DIVISION uses the General and Stock Rules with the following exceptions:

The power source may not produce more than 15.5 volts at any time during the run with or without the vehicle running.

Enclosures in the Trunk Division must be installed in the trunk. Neither the enclosure, nor any device(s) affixed to the enclosure may protrude above the factory rear deck. The rear deck may not be cut out or modified in any way (to include sheet metal, and rear deck coverings). You may however remove the factory speakers normally located in the rear deck. Amplifiers must be located in the trunk area. Amplifiers may be attached to the seat back and lean forward with the seat back during testing but must not interfere with the seat being placed back into the factory position. Vehicles without a “Trunk” will not be allowed in this division. “Hatchback” vehicles are not allowed.

Rear passenger seat backs may be folded down during testing but may not be removed, nor may any part of the entire rear seat assembly be removed or altered. Rear seat backs must not have any exposed sound deadener.

Amplifiers may be attached to the seat backs and folded down during testing. In such cases the seat must be able to return and lock into the factory position after testing.

OEM interior panels may be upholstered or painted, but may not be modified or removed in any way but with these exceptions:

Factory panels in the trunk area may be removed to facilitate the system.

XTREME DIVISION

XTREME DIVISION uses the General rules with the following exceptions:

(Many of the following rules and drawings are courtesy of Wayne Harris and DBDRA. USACI would like to thank Mr. Harris for his generosity in allowing us to utilize these guidelines for the cabin measurements.)

A spotter must be present to assist the driver at any time the vehicle is moving.

The power source may not produce more than 18.0 volts with the vehicle running.

Competitors will NOT be allowed in any vehicle under test over 165db in the Xtreme division.

Modifications will be allowed to the interior of the passenger compartment. The floor, ceiling and dashboard may be modified. Ceilings may be lowered and floors may be raised.

Modifications to the exterior of the vehicle to accommodate the sound system are allowed

No seats are required.

The factory windshield and side glass may be replaced. There must be at least one 8.5 x 11 inch unobstructed view port directly in front of the steering wheel. There must be two view ports to allow an unobstructed view of the SPL sensor during testing. These view ports must be located on opposite sides of the vehicle and behind the A-pillar. The microphone/sensor may be placed anywhere forward of the B-pillar within the following guidelines.

The microphone/sensor may be placed in a foot well or other microphone/sensor specific location only if the location and entrance to said location is below dash level. The location may be no more than 10 inches deep and no less than 13 inches in height and width. If the microphone/sensor is to be placed above dash level, it may only be placed on the windshield, 12 inches from the passenger side A-pillar, 4 inches from the top of the dash, and one inch from the windshield.

A dash will be required in every competition vehicle.

The highest point of the top of the dash may not extend above the horizontal plane determined by the base of the windshield.

The lowest point of the top of the dash may not be located any lower than 3 inches below the horizontal plane determined by the base of the windshield.

The minimum depth of the dash at the center of the vehicle is 6 inches when measured from the edge of the dash to the

windshield. The maximum depth shall be 16 inches

25

The plane of the dash bounded in the front by the firewall, in the back by the trailing edge of the dash, and for a distance of 12 inches to the left and 12 inches to the right (measured horizontally) of the sensor placement location must be completely flat with respect to the ground.

The dash may be completely solid (with no holes or perforations) and must extend front-to-back from the firewall to the trailing edge of the dash, and side-to-side from the windshield pillar on the driver’s side to the windshield pillar on the passenger side.

The trailing edge of the dash (the edge of the dash that faces the passenger compartment) must be straight and perpendicular to the centerline of the vehicle when viewed from the top.

The center console may not exceed the height of the lowest part of the top of the dash.

A minimum “open space” distance of 13 inches (33.02 cm) MUST be provided at ALL points between each side of the center console and each door. (Measured horizontally and perpendicular to the centerline of the vehicle.)

Center consoles must not interfere with the “String Test”. Competitors may “notch” their consoles or make the console easily removable to comply with this requirement. Notches may be taped shut after the string test.

If no center console is present, then the 13 inches (33.02 cm) closest to each door will be treated as the open space area.

Competitors MAY construct a roof build-down if desired.

Additional Guidelines: The build-down may not extend more than 3 inches (7.62 cm) below the top of the doorjamb.

For those locations in front of the door (between the door and the windshield) and behind the door (between the door and the baffle board), the roof build-down may not extend more than 3 inches (7.62 cm) below the lowest part of the top of the doorjamb. For doors with curved door openings, the reference point shall be defined as the intersection between two imaginary lines.

Competitors MAY construct floor build-ups.

Competitors MAY construct a removable or flip-down panel(s) to cover the OEM foot wells.

Additional Guidelines: In the interest of safety, competitors are encouraged not to modify the vehicle’s OEM foot pedals (accelerator pedal, brake pedal, clutch, and parking brake).

Competitors MUST maintain a minimum 30-inch (76.2 cm) vertical separation between the headliner (roof build-down) and the floor (floor build-up) at ALL locations within the passenger compartment except over the center console and the dash.

26

Additional Guidelines: A 30-inch rod will be used to determine compliance. The judge will hold the rod vertically and move it around inside of the passenger compartment. If the rod’s movement is impeded, then the vehicle fails compliance with this rule. Bracing located outside of the “open space” area shall not constitute an impediment to this test.

In the above example, the top trailing edge of the dash defines the vertical plane that is used to establish the front-to-back Free Space area. (Note how the dash is NOT located completely beneath the OEM windshield location.) Not to Scale.

In the above example, the OEM top windshield frame defines the vertical plane that is used to establish the front- to-back Free Space area. (Note how the dash is located completely beneath the OEM windshield location.) Not to Scale.

In the above example, the top trailing edge of the dash defines the vertical plane that is used to establish the front-to-back Free Space area. This example also depicts how changes to the roof build-down and floor build-up can be made provided a minimum al distance of 30 inches is maintained. Not to Scale.

27

Competitors MAY build-out their door panels if desired.

Additional Guidelines The maximum distance the build-out may extend into the passenger compartment is 6 inches). (Measured from the sheet metal of the door where the OEM door panel was originally attached.)

Cavities in doors are prohibited. (A cavity is a negative build-out that protrudes into the door’s interior space.)

Competitors MAY install bracing if desired.

Additional Guidelines and Examples: The maximum aggregate width for all bracing in front of the B-Pillars is 6 inches. (To determine compliance with this guideline, find the widest point on each of your braces. Next, add these maximum widths together. The total value must be 6 inches or less.)

If the brace “Y’s” into 2 or more arms, then the width of the brace shall be considered as either the sum of the widest point on each arm, or the maximum width of the single “leg”, whichever is larger.

Example: A competitor is using a single 4” x 4” brace from the roof to the floor. The widest dimension of the brace is 4 inches, so the competitor is in compliance.

Glossary of Terms

OEM: This refers to the original equipment produced and installed by the original manufacturer of any given vehicle. Items such as door panels, carpet, external accessories, internal accessories, upholstered treatments, bolt patterns etc.

B-Pillar: The forward-most leading edge of the B-Pillar is the reference point for this standard. In classes where applicable, this point of the B-Pillar is the point where equipment may not protrude past going forward. The only caveat to this standard is in the case of a vehicle B-Pillar structure that leans backward going upward. This is very common in most passenger vehicles and light trucks / vans. If the bottom of the B-Pillar is forward of the top of the B-Pillar, so may be the audio system apparatus (enclosure, subwoofers, amplifiers, etc.)

Roof: The roof of a vehicle is defined as the lowest point of the ceiling of the subject vehicle interior, and is limited to upholstered coverings, i.e. headliner, as well as any horizontally affixed trim panels. The exception to this definition applies to any trim panels affixed to or retaining the headliner that extend straight downward more than four (4) inches.

Run: The competitor’s designated opportunity to officially test their vehicle in the competition lanes. Competitors are allowed to test their vehicle, remedy for 3 minutes, and resume testing with a secondary opportunity to retest.

Re-Run: An additional competitor-paid opportunity to re-test their vehicle a SINGLE time after their ORIGINAL competitor-paid Run.

Rear Deck: In vehicles with trunks, the rear deck is defined as the vehicle structure joining the rear window lower core support to the rear seat structure, effectively providing necessary bracing for the rear of the vehicle chassis, as well as a solid separation between the trunk compartment and the vehicle cabin, commonly used to facilitate installation of OEM lighting, audio, etc. The term “rear deck” applies to not only the metal structure itself, but also the OEM rear deck upholstered coverings, and any OEM trim panels mounted directly to it, as well as other OEM fixturing such as third brake lamp assemblies.

Head Judge: The USACi Staff member assigned to facilitate the competition event, operate the Term-Lab software, open and close the competition lane(s), make final decisions, assign official competitor event placement, and award distribution.

Verification Judge: The USACi Staff member assigned to ensuring all competitor vehicles are safe to compete, adhere to USACi vehicle compliance guidelines, proper class placement, proper amplifier clamping procedures, proper mic/sensor placement, and overall safety and efficiency in the competition lane(s).

Build-Up: The practice of intentionally adhering or affixing ANY material to the interior ceiling, interior floor, interior fire-wall or interior door panels of a competition vehicle solely for the purposes of decreasing the net volume of the cabin space to provide for a potentially increased SPL score. Example: 2 Layers of automotive type sound deadener applied to the floor of a vehicle is acceptable, but 47 layers of the same material would be considered a build-up.

Window Line: This term applies to the point where any referenced outward facing window glass meets an interior OEM trim panel at the subject window’s bottom horizontal edge.
