only change i see is street stock, Any number of amplifiers may be used. However, the maximum total RMS power in the system must be 2000 watts or less.

Thanks for the link. What all is covered under vehicles mods? No vehicle mods in Street A/B/C. Does it only pertain to "structural" changes? Don was asking about my door pods last weekend. Am I going to have a problem with them? and for Street Stock - 2000rms TOTAL power... does this include your highs amp if you use one?

The extent to which modifications to the passenger compartment are allowed is limited by the division a competitor is competing in. (See Section 2 entitled, "Competitor Classification System" earlier in this rulebook for a complete listing of competition divisions and classes.)
Additional Guidelines:
* 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.
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.
General Restrictions Regarding Sound Damping Materials:
* Sound damping materials may be used to reduce vibration when installed in accordance with the manufacturer's recommended installation instructions. In certain dB Drag Racing divisions the maximum amount of damping material that may be used at a given location is limited. (See the Passenger Compartment Restrictions section for each division for specific limitations.) Some examples of these limitations are given below.
Street Division Examples:
A Street Division competitor may use 2 layers of damping material on the inside sheet metal of his roof. However, the competitor may not use 2 layers of damping material on his roof and another 2 layers on the backside of his fiberboard headliner because this would result in a total of 4 layers of damping material in this location.
A Street Division competitor may use 1 layer of damping material on the inside sheet metal of his door and another layer of damping material on the backside of his door panel because 2 layers of damping material are allowed at any given location. On the other hand, the competitor may not use 2 layers of damping material on the inside sheet metal of the door and another 2 layers of damping material on the backside of the door panel because this would result in a total of 4 layers in the door location which is prohibited.
General Restrictions Regarding Seats:
* Go-Cart seats, arcade game seats, dune buggy seats, etc. are not considered equivalent OEM seat replacements because they do not closely resemble the OEM seat in structural rigidity, cosmetics, or size.
* Seats must bolted in the OEM locations of the vehicle with the exception of the Extreme Division.
* A minimum separation of 12 inches (30.48 cm) must be maintained between the seat and the sensor location at all times.
* If a seat originally came with a headrest then the headrest must remain attached to the seat during competition.
Additional Guidelines:

door panels are always a sticky question. Every judge has a different out look on them. In Carlisle PA there was 4 Judges looking at one civic with door build outs. each of us had a different out look on them. by the end of the show the guy was put in two different classes before we all came to the same understanding.

your pods are fine, you could always run any number of amps in street stock, there have been NO changes made to the rules yet. if your planning on building wait till the rules actually come out as the rules on the site are just 2009 rules with the date changed to 2010.
