Engine Noise :(

You have to have a clean metal surface so go to your ground and SAND the paint and all off. Also as far as I knwo and all the head units I have put in the z's there is not factory ground wire that is used in the aftermarket harnesses. So I would check on those if you did somehow use the factory ground unhook that wire and ground it to one of the 4 bolts were the shift knob is. But the most important thing is to sand that primer and paint off that ground spot.

I looked at the pics on the web site that was linked to your response, and noticed you had a blue 370z you did an install on. In the back where the crossbar is (the one directly behind the seats) directly below that in the little cubby of the trunk there are two silver screws attached to a black tab that is screwed to the trunk. The one on the left is where I bolted down the ground. So, should I take the bolt off and sand off the paint from that, or can I move that tab so that I can sand the trunk below that and mount the ground between the black tab and the trunk itself? Or, is there a better place to put the ground?
