Alright, I'll start by saying i am looking for an SQL setup and that i own a ext. cab truck. Now for the sub setups i was thinking (4) 12" Alpine Type R's, (4) 12" Cerwin Vega VMAX's, or (4) 12" Kicker CVR's. The amp will be a JBL GTO1200.1, the componants are Infinity Kappa 60.5cs, the speaker amp is a JBL GTO 75.2 and the Head Unit is a Panasonic CQ-C1300U, the subs will be downfired in a sealed/ported(cant decide) box built to specs
hard to tell you what will sound better, but i personally like the compvrs a little more then the others. but they will all do it. its just what YOUR ear likes. all decent subs though
