11/1/07 NOTE: The entire system has been ripped out for weight savings. I've gone back to a decent Kenwood had unit and Pioneer and Kenwood speakers with a small 8" sub mounted in the rear deck. Yanking all this stuff saved me 60+ pounds which in a quarter mile definitely helps. I'm leaving this page up though for others to see what I did do.

Heres the seats removed to put in some B-Quiet and to run my power/RCA/speaker wires: 
MB Quart PSD216's - 6.5" woofer in the doors and a surface mount 1" tweeter. The crossovers are mounted under the radio and I have 12 and 16 guage wire running through the factory rubber grommets out to the speakers: 
The rear deck has the refrence series components on each side with the 8" mounted right to the rear deck after some fun wood cutting and cutting of the rear deck metal: 
A simple amp rack I built for the amp and the rear crossovers:
