all equipment must be bellow the window line and behind the b-pillar.
any mods u make need to be for cosmetic reasons or working reasons(like u can fit a 3 way setup in ur door in a new glassed enclosure, if its a show car type thing), they canot be done to help your score out.
someone else might be able to clarify it completly, but thats how i understand it.

A Special Note on the Installation of Speakers other than Woofers:
* Speakers that are less than 10 inches in maximum diameter may be installed anywhere in the vehicle, provided their installation does not violate any other existing rule.
* It is permissible to strengthen door panels at the location where speakers are installed in the doors.
* Door pods are also permissible, as are custom fiberglass "build-outs" or other modifications that are made in order to accommodate speakers in the installation location.

* For clarification purposes, the dBDRA uses the term "modification" to describe changes to the vehicle that have been made in order to accommodate the sound system or to improve the competitor's score.
Some examples of passenger compartment modifications include:
o Replacing the OEM glass
o Replacing the OEM dashboard
o Replacing the OEM seats
o Reinforcing the door panels
o Floor build-ups and roof build-downs
o Removing or replacing the OEM center console
A Special Note on Equivalent Replacements:
* There are several areas in the rulebook where the term "equivalent replacement" is used. The dBDRA considers an equivalent replacement to be a replacement that closely resembles the OEM product it replaces in both form and function. This includes structural rigidity, cosmetics, and size.
Example:
If a competitor is replacing the door panel on a vehicle, it would be acceptable for the replacement to be made of 1/8-inch (3.175 mm) thick fiber board covered with upholstery material, since the structural rigidity, cosmetics, and size of the replacement panel are similar to those of the original panel. On the other hand, a replacement panel made from 1-inch (2.54 cm) thick MDF would not be permissible because the structural rigidity of the replacement panel is different from that of the original. Please note that in this example it is not the thickness of the replacing material that dictates what is or is not acceptable. Rather, it is the similarity of the structural rigidity that was used as the metric.
