Hello. I have a DEI Studio 3124 12" 400w RMS 4 OHM single VC sub-woofer and I need to get an amp for it. Would it be best to get an amp that is also rated at 400w RMS? Right now i'm looking at the Rockford Fosgate Punch 401S. It's bridged RMS power is rated at 400w x1. Would this be a good match? Thanks. -JP
