I have the Pioneer DEHP8200. Two JL Audio W-0 in a bandpass box powered by a Rockford Fosgate 390watt amp. Plus two Rockford Fosgate 8" speakers and 2 1" tweeters (i don't know the brand) in a two truck speaker boxes powered by a Rockford Fosgate 100watt amp. Also I have Ecplise 6X9s in the doors. Also A 1farad Cap.
I also just installed 5.6" (got them from a friend for 190 each) tvs in the headrest with the PS2 hooked up to the TVs. Looks very nice.
