this amp is confusing me. its a 4 channel amp that i hooked up to my subs, and 6x9s. I had it hooked up yesterday for the first time and everything was working fine. I had the two subs "bridged", and the 6x9s running like normal. Everything sounded great, hard hitting bass, and crisp clear vocals. Now today we put it in my brothers car just to see how it would sound and it shuts off as if it got too hott or something. So we said screw it and put it back in my car and now it will only play for a few minutes then shut off. Whats up with this Clarion APA4101???
