i got a big problem my power line came off my batery, so i took the amp out thinking it was at fault. came back around and found the wire that came off so when i came to put the amp back on it lit up the offset led. it only does so when i plug in the LEFT channel RCA and i have no resistance at all between the center and the middle of that RCA jack so as far as it goes i can still listen to one sub, but it's just not the same.... anyone have any answers
