Why are dead-set on Polk for your amp I would spend the extra money for a bigger amp. The RMS on that sub is 700 watts so a 500.1 (since it's ony 350 watts RMS). I would try a JL Audio 1000.1. It's a lot of money but when it comes to car audio you def get what you pay for. As for the power kit tsunami makes a 4 guage kit that includes a 1 farad cap.
