I was trying to be nice....It was clipping, you just didnt know it. ALL Pyles amps clip. Only way to tell if its clipping is with an o scope. And estimating them at 65% efficiency is giving them a bit much. I'd say closer to 50% efficiency.
Um no this is not the answer
Key Features
Amplifier Type Dual Channel
Channels 2 Channel
Input Voltage 10.5 volt
Bridgeable Bridgable
RMS Power at 2 Ohms 3000 W x 2
RMS Power at 4 Ohms 1500 W x 2
come on 3,000 watts a channel at 2 ohms at 10.5 volts
Everyone on this board would get rid of their amps and run Plye - at least I know I would
