I was looking at the rules of SS NW and I noticed this:
quote: Section 6 - Installation Regulations:
The dBDRA defines a speaker wall as any subwoofer enclosure and / or baffle board that exceeds the height of an imaginary plane that stretches horizontally from the lowermost point of the window opening in the driver's door (where the side window enters the door frame) to the lowermost point of the window opening in the passenger's door on the opposite side of the vehicle.
Additional Guidelines:
* Compliance with this rule may be verified by using the following test: Two judges position themselves on opposite sides of the vehicle. A string (or wire) is passed through the open window on the driver's side, through the interior of the vehicle, and out of the open window on the passenger side of the vehicle. Both judges should then pull the string so that it is taught while resting against the lowest point within the window opening. If the enclosure in question does not exceed the height of this string, then the enclosure is not considered to be a wall. If any part of the enclosure exceeds the height of the string, then the enclosure is considered a wall. * Any components that are attached to (or resting on) the subwoofer enclosure, including speakers, amplifiers, signal processors, etc., are considered to be a part of the subwoofer enclosure. * Competitors may not deflate their rear tires or otherwise change the normal attitude of the vehicle with respect to the ground in an effort to circumvent this test.
Exceptions:
* If the subwoofer enclosure is installed in the trunk of a vehicle, then compliance with the "wall test" is not required.
and related to this:
quote: A Special Note on the Super Street No Wall Class:
The rules for the Super Street No Wall Class are identical to all of the other classes in the Super Street division with the following exceptions...
* Speaker walls are prohibited. * Modifications behind the B-Pillars may not extend above the plane that is used to determine compliance with the "wall test". * All auto sound equipment (with the exception of source units, video displays, and signal processors) must be located below the plane that is used to determine compliance with the "wall test". * Floor cut-throughs are not permitted. * Battery boxes located underneath the vehicle are prohibited.
If my enclosure is in the trunk behind the rear seats and above the window line, then it is allowed, correct? Well according to the exception rule, as it specifcally states that the wall test is not applicable if the enclosure is in the trunk.
