I had some grounding issues with my 96 Integra. Alternator whine, pop-on & off
I tested a pioneer hu in place of my Eclipse hu, and it all went away.
Well before i could figure it out, i sold the teg and sold the system except for head unit.

I bought an 04 WRX and installed the Eclipse 8443 in place of stocker.
Just installed the Rainbows and Tru this weekend and low and behold i have alternator whine once again. What the hell?????

do you guys have any suggestions to fix this? Would grounding the head unit to the chassis instead of the factory harness help?

Any help would be greatly appreciated.....TnT
