Case 1 - The subwoofer enclosure is located ENTIRELY underneath the rear hatch OR the highest point on the enclosure is located underneath the hatch.
In this example the judge will measure from the highest point on the enclosure (including amps, accessories, woofer surrounds, etc.) to the horizontal plane defined by a point located at the top center of the hatch opening. (Please refer to Figure 15-6, 15-7a, and 15-7b.)
Case 2 - The subwoofer enclosure is NOT located entirely underneath the rear hatch. In addition, the highest point on the enclosure is located directly beneath the headliner.
In this case the standard wall test technique will be used. (From the highest point on the enclosure to the headliner.) Figures 15-6, 15-7a, and 15-7b do NOT apply in this case.
