battlewalrus Posted February 11, 2012 Author Report Share Posted February 11, 2012 If you dont have a ground it will use the rca shield as a ground. Bad shit Does it mess the amp up or only the head unit?

Ray Posted February 11, 2012 Report Share Posted February 11, 2012 What ground? At the amp? And no, it doesnt. Need to do a ohm check between amp ground terminal and sheet metal of the car. That should read 0.00 ohms. Not like 80 ohms.
