I'm still running a phoenix gold xs amp, if that gives you any clue as to the last amp I bought. All these new brands and watts for cheap has my head spinning.
I have a phoenix gold xenon 600.1 or an audioque 1200.1 on mine. I give the edge to the phoenix gold when putting those 2 head to head. I would look for a solid 1200-1500 rms. What's your budget?
