Poblem: sound from speaker randomly cuts in half... Just installed a new HU today, because I thought my old one was dying. Reason I thought the old one was dying was because whenever I moved the harness on the back a certain way, the sound from the front speaker(s) would cut in half about. After installing my new Pioneer Premier DEH-P880PRS, the problem still exists -- but not when I move the harness...just randomly on its own.
System consists of HU, front components, sub, mono amp and 2ch amp.
I'm going to try a better ground for the HU and maybe the 2ch amp. Any other ideas as I try this? I've had this issue for a little while now, and cannot seem to solve it no matter what wires I re-run or grounds I change.
I'm wondering if the amp is going bad.....but sometimes hitting the side of the console fixes the problem temporarily -- which makes me think the BCM might be related somehow. I'll try powering speakers off a HU later anyway... Also, I think this BCM problem may have developed when routing wires through the drivers side door. After routing through the door, whenever I open or close a door there is some random noise in the system (whenever you press that door sensor thing)....
Anyways, that's a lot of random information.. thanks for any info.

guess next logical step is to try powering components off of HU and see if problem is still there....just too lazy to do that now because its cold and since crossovers are buried and wires are most easily accessed at rear of car... hopefully warmer tomorrow

Main problem is the intermittent playing of music at normal levels and randomly having the volume cut in half (approximately) out of the front amped speakers... which I think is caused by a failing amp.
