Don't believe me.... been there, done that.
I never said don't use it (hu) or amp ground...Just add the wire to remove voltage difference.
the12volt.com has more for you to read....
Does this mean that you would ground the HU up front, ground the amp in back, and then run a wire between the two grounds?
