the subs arent going to get all the power they can because the amp that comes with it is just a 750 and two subs each are going to share one

Answer 1

chances are your stock charging system would last, I ran 2 Kicker KX1200.1 amps and 2 15" L7's in an 03 focus.

Upgrade your big 3 under the hood, and put a deep cycle battery in. Worst case scenario you will have to get your alternator re-wound.

Answer 2

bad choice to buy 4 subwoofer speakers for a car...
