I think my amp is stuffed its a coutic 480qe 4 channel. Here the deal it gets power to my speakers, then cuts out after 3 seconds (goes into protection mode). During that three secods the left speakers pop and distort. I have swapped the wiring, so then the right side pops. So i know it is not my speakers and wiring and it is definetely the amp. I hooked it up to my sub bridged but all it does is a breathing motion (no sound) but doesnt cut out. What the hell is wrong with it?
