[QUOTE="Firewalker, post: 8850242, member: 676743"] For the head unit ground you just wire the black coming out of the head unit wiring harness and you ground it to a bolt behind the head unit. Done it that way for 30 years and it works. Always a spot behind the head unit in the dash where you can do that with the head unit. Some head units even have a separate spot on the head unit to run a ground from a bolt that is in there or screw to a spot in the dash. Never have nor will I ever run a ground from the head unit back to where my amp is grounded at. Pointless when you have those options in every vehicle. As far as the amplifier ground goes. Find a good spot in the chassis or frame or something like that. Remove any and all paint from the area including the bolt and use it as a ground. Don't use a screw or something screwed into the vehicle someplace. [/QUOTE]
