hey everyone, right now I have a Rockford Fosgate Punch 360.2 amo running bridged, 360 watts RMS, to my Polk MOMO 12" sub. the sub is a single voice coil 500 watts RMS @ 4 ohms. i am in the market for a new amp and i would appreciate any oppinions and suggestions on what amp to get and where to get it from. the new amp should deliver 500-600 watts RMS.

thanks,
Raj
