stripped my rt of stereo before i sold it. Got a rockford 12" suba and a 4 channel amp. uprated all 6 speakers, but never sounded really special. Now got a clio 16v and want to uprate the stereo. Accquired an alpine v12 4 channel amp off a mate, its the b****cks! definately goona have enough power for anything. Any ideas on a setup? Was wondering if it was worth getting 2 subs, or just havin 1 quality sub and then uprating all the speakers. Thinkin that 2 subs might make the boot and back bumper rattle too much sounding crap from the outside! Possible set up: 2 JL w3 12" subs ran by the apline v12, then use my other amp to run 2 quality 6 by 9s and 2 front speakers. What do u reckon??
