I have two '07 CompVR 12's in my car in the stock Kicker ported box right now and they're working fine, but there's a pair of '05 CompVR's someone is selling for $200, so I was thinking about getting them and doing a nice install in my car. They're all dual 2 ohm VC subs, and I'm thinking of getting new amps & new mids/highs to complement them. How big of a box would all 4 be, and i'm assuming I'd want it ported. Also, is there a way to wall them off so I can still have trunk space (for bookbag, bags, etc.) I know I'll need an electrical upgrade big time if I do too. Thanks guys.
EDIT: Okay, I decided instead of going Memphis amps, that two kicker ZX750.1 amps will work. Each sub is dual 2 ohm, so wiring the individual sub in series, then pair them up in parallel puts them back at 2 ohms, meaning minimum 750w RMS to each pair, which is good because the RMS rating per pair is 800w RMS (400w RMS per sub). What would you guys suggest as the best speakers/amp combo for mids/highs? (Remember, 5 1/4" + tweeters in doors & 6x9's in back.
