I'm pretty happy with my Polk 12s and Hifonics 1200Watt Brutus setup, I got other shit hooked up too, cap nd all that. But for a pretty cheap system it his pretty hard, and I'm really happy with it, I still make people turn heads with it only 1/3 of the way turned up.

I hope you do the same with this set up, but personally I woulda gone with the L7 Kicker, but I know how money can be a bitch these days, I could go on forever about it.
