My old car had:
Pioneer Premier DEH-P520 HU
Pioneer Premier CDX-656 6 disc changer
2 RCF 4" midrange speakers (front)
2 Pioneer TS-T22 1" soft dome tweeters (front)
2 RCF 5 1/4" midrange speakers (rear)
2 Pioneer TS-T15 3/4" soft dome tweeters (rear)
2 Kicker Solo-Baric L7 15's in sealed enclosures (first model, not the newer style)
2 Kicker ZR240 amplifiers (front sound stage)
4 Kicker ZR360 amplifiers (low end)
Ripped it all out before I sold the car....
My new car thus far has:
Pioneer Premier DEH-P940MP HU
Pioneer Premier CDX-656 6 disc changer
Front stock speakers in door, stock tweeters opposite mirrors
6 Kicker CompVR 10's in sealed enclosures
2 Kicker ZR240 amplifiers (one for mids, one for highs)
4 Kicker ZR360 amplifiers (low end... 3 voice coils per amp)
I don't plan on using any speakers as rear fill, as I'm going to run my deck in pro mode and use the built-in crossovers. I do plan on replacing the front components, however. Pictures coming soon once it's decent-looking.. right now it's a bit ghetto-ish
edit:
Oops, almost forgot... 2 Optima red tops in the trunk and one under the hood too.... and tons of wire... and one deaf driver
