My issue is that I'm running the current amp bridged into stereo to get the 200x2 rms for my components, and the amp keeps overheating. I don't think its truly stable at 4ohm like they claim.
I'm hoping that the better Alpine Amp can push the same amount of power, but run cooler and cleaner...
Comments?
