What kinda car do you have?

My CD player is a Kenwood (something or other) 180watt x 4 channels. Its pretty nice, got the little remote and plays mp3s, ... what else could be niceer = $180

You probably mean 180Watts total, which would be 40 x 4 channels. Since the max any CD deck out there can currently go is 212.

I have a 1985 Jeep Cherokee, white, it's ghetto but the sound system rocks, drives very well, gets great gas mileage (V6 instead of V8, I dont need the extra power, and it saves a lot more gas!). I have a Pioneer (good decks) 50W x 4channel CD deck, with fold down (where you put the cds) face, that is also detatchable, I cant remember the model number but I think it's DEH-*something*3500. 2 12" Kicker VR Comps, 4 6" Rockford Fosgate Punch speakers, and I am getting some more (crossover), with my JBL 600W amp.

Oh and a note for everyone... DONT GET 10" subs! 12" subs arent that much more, and they hit four times harder than a 10 can! Grrrrrr.....
