ok so i got 1 12" mag ( newest one, but not the one that hasnt came out yet) ran off a kicker kx1200.1 and in the next couple weeks i will be upgrading my alt (250amp mechman alt) and batts. since im getting my electrical system upgraded, i will also like to upgrade my system......... i was thinking of adding another Mag and a kx1200.1 back there, but then i also thought i could go a diffrent route and possibly get a 15" BTL or another 15" or 12" sub that can handle close to 3000 watts. what are your guys thoughts on this? what will give me the most output if my install is done well? this is a DD by the way ( 2006 civic ex 4door) ............. want to be loud , but pretty good.
