Hey guys, I've got a rather annoying problem with my Polk PA1200.1 Monoblock amp. when I play it at high volumes it just cuts out after about half an hour or an hour of listening time!!!!! Its connected to my alpine CDA9987 and powers a Polk SR124DVC subwoofer. The blue lights and everything are still on, so I know its still powered up, but it just doesn't deliver anything to my sub!! It comes back to life a day or two later, and its like nothing happened at all...until it just cuts out again when I listen to loud music! It doesn't seem to be excessively hot so I dont think its over heating, and my gain is only set to about half since I dont like a very loud low end. I'm totally lost as to whats happening and I'm about ready to rip this amp out and go with another brand - JL audio or ARC audio.... Anyone who knows anything about this - please help!!!
