T-Hybrids got the best advice so far. I wouldnt go as far saying the the RCAs are for sure the culprit. But, that is a good place to start. If it is the RCAs, just replace them w/ cheap ones. When I say cheap I dont mean 5bucks/ pair more like 10-15 bucks a pair. Anything above that would be just a waste. Now back to the problem, I would have to say that it sounds more like you lost a ground. Be sure that all of the connections are still in good shape behind your head unit, then just work your way back. The ground connection at your amp is probably the most crucial of the amp connections. More current travels throught the ground cable that goes throught the primary cable. So ensure that your ground is firmly fixed to the cars chassis, wire should be no longer than 18 in and notshorter that 12 in. Good luck, hope you get it all workin'. I would offer hands on assistance, but I am still sailing around in the persian gulf. I wish I was home working on the civic.
