I just replaced my 4ch amp that crapped out on me a few months ago, I've been just running my rear speakers off my sub amp for the time being. Everything had worked fine before the amp stopped working, but I hooked up the new clarion quickly the other day and it appears only the rear rca outputs from my head unit are supplying sound to the amp. so in 4 ch mode i only get sound to the rear speakers. Its not the wires I swapped both, and in 2ch stereo mode I get "fake sound" to the fronts. And is this wasn't bad enough the amp cuts out on me occasionally real quickly and starts working fine when I turn it down. I suppose this is an electrical problem. But if anyone has any ideas on these problems I'de appreciate it, thanks
