Ok fellas, here we go. I have a 2003 jaguar s-type factory head unit with a line out converter going to a 4 channel amp. I drilled and tapped a bolt to my frame for the ground. My battery is in my trunk so the ground does run across my main power wire for my car, but only for a couple inches. I've also installed 2 ground loop isolators between my line out converter and the amp. Oh yeah, I also grounded my head unitto my chassis. I don't know what else I can do. Any suggestions would be greatly appreciated.
what kind of line out converter is it? Also, did you sand the metal where you put you bolted the ground to? How long is your ground?
ok i just sanded my contact point for my ground but no luck, it still makes noise. It's a scosche line out converter the kind they sell on crutchfield. the ground is about two and a half feet long. HELP!!!
