[QUOTE="TeenWolf, post: 1003048, member: 561987"] Let’s see if I have this straight... Front speakers: Hooked up to 2 channels on your 4 channel amp Rear speakers: Hooked up to HU Sub: Hooked up to other 2 channels on your 4 channel amp (bridged) Front speakers have no distortion. Rear speakers have distortion. Sub is f*ked. Man...If this is right, then it sounds like a tangle! You said that your front speakers are not cutting out, which means the amp is not shutting off. Maybe I'm wrong, but if the amp isn't getting enough voltage, then you would have problems with the front speakers too. Is it possible to have a 4 ch amp that only has some of the channels bad? If not, then the amp isn't the problem. It is possible that the sub is bad too. The rear speakers off the HU are producing distortion, which would have nothing to do with the amp. You say that you hear noise between tunes, but the distortion is probably there all the time...the music just drowns it out and you only hear it during "quiet time". I'm leaning towards a HU problem. I have a problem with the decibel level on my sub and I'm pretty sure it's a bad pre-out. Your HU could have a good pre-out for the front speakers and a bad pre-out for the sub. And the HU internal amp could be faulty too. Could be wiring, but you said that was all solid. Whatever the problem is, you have a lot of trial and error ahead of you. Good luck! [/QUOTE]
