Disconnect the all the audio inputs and outputs. Then plug each one in individually until the amp goes into protection mode. When it goes into protection mode then you have found what is causing the problem and trace it from their.

Are you hooking it up to multiple subs?? Sometimes you will end up with 1 sub that has it's polarity switched. I had a JL that was switched, then after a month or so everything got funky, it had switched polarity somehow(I'm clueless on why.....)
