I just bought 2 Kicker CVR 12". I have a ported box...looking to upgrade to pro. i want to power my subs full rms (450 each). i already have the 2500w wiring. i have a 1986 coupe deville and I WANT BASS!!! so if you have any tips besides dynamating, probox or anything like that let me know as well. i may upgrade to cvx later. and i think i want a custom box with 4 wholes for 12" subs. is this too much for my car?
