Started upgrading the original Clarion XMD1/CD changer out to a new Fusion Apollo unit. While the Clarion wasn't high end (OK maybe it was in 2000), it worked and sounded OK. However, once I changed out the head unit, I had terrible noise coming from the system. I had what sounded like digital noise coming from the head unit when connected to the amps, noise on the RCA cables (touch the center lead and get feedback), and alternator noise once the engines were running. A perfect trifecta of bad audio ju-ju!
I expected similar to better sound from the new unit, but just adding this new head unit added all kinds of noise that wasn't there previously.
Things I've tried...
1) Replaced head unit - No improvement
1) Ran gound wire from head to amp - No improvement
2) Tried High end RCA cables - No improvement
3) Tried twisted pair RCA cables - No improvement
I'm assuming a bad ground or grounding issue. The wiring looks to be stock/original. I'm going to try to home run the ground..First to the battery and possibly the chassis. Not sure where...is it a trial and error thing?
Any advice?
