320W RMS and Peak is 620W..... What Kind of amp do I need ? I had Fosgate amp in the past and I am willing to get another, but how many watts should i get the amp ?

 

320 Watts RMS - simply amazing. You should be fine with the P5002 @ 150 Watts RMS per channel @ 4 ohms. That was unless you where thinking of one of their older ones.
