First, check your gains and make sure they are set properly. Same goes if you have bass boost. After that, double check your grounds and connections to make sure they are secure. Also, check your wiring to make sure everything is wired correctly. If that doesn't fix your problem, you're either pushing your amp too hard or something is wrong with it.

That's not good. You are properly clipping your amp and sending it into protection mode. Check the sticky thread about properly setting your gains.
