wow that's a bummer to hear. It'd kill me too everytime my amp shut off when i turned the volume up. I want to say that you're overheating the amp and that u should have better ventilation for it, but i can't be 100% sure. How'd u hook the spkrs up? Like i also want to say that maybe your amp can't handle the load of your spkrs. Anybody else think of something?!?
