well, my amp that im using for my subs if MESSED up. i was driving, and all of the sudden it cut out. so i went back and checked it out, and well....the amp had power, and the turn on lead had power, but the amp kept shutting off. then i realised, every time it shut off, the protection LED would come on. then the protection LED shut off, the amp would turn on, and immediately it would shut back off. so i pulled the RCA's off, and it stopped. it seems to only happen with channels 3 and 4. i have 1&2 and 3&4 bridged, each going to a 4 ohm sub, so its not a resistance issue. when i plugged the RCA's back in, it would cut out as soon as the outer ring part would come in contact with the outside of the RCA jack in the amp. could my RCA be grounding out? but why then why do channels 1 and 2 have no problem? what else should i check? please help me, my warranty expires in 8 days and i have to make sure its not a wiring issue before i go to them. oh, i jsut remembered, my RCA, at the deck, one of the plugs is broken, like, completely broken. so one of the RCA's has no signal, while the other does. it was working fine for a few days. now all of the sudden it doesnt.
