ok, here is the plan to building up my system...
Kenwood KDC-MPV7019 (mp3/CD deck) ($279)
two Alpine 12" SWR-1241 Type R ($149 each) with Alpine Amp MRV-1507 ($489)
two RF 15" RFD2215 ($209 each)... dont know what amp i could use with this though. i'm sure i'm gonna have to spend some money on the amp.
