Dont even get me started i am gonna move the ground over, scrape the paint add a star washer and be done with it...its amazing how i have always done the work myself in the past and had zero noise issues, take it to a shop and its shitty..and another screwup is the installer didnt use the remote out f my dsp to my amps. had to run the wire for that as well, i will never go back thereThe fact that the bolt is actually threading into the body of the car (assuming that its the case) still makes it a ground, definitely not a GREAT ground but nonetheless a ground. An EZ or quick fix would be to add a star washer and/or a copper washer between the wire terminal and the bolt head and also make sure that the bolt itself, or the threads it goes into, are not themselves painted.
All that said of course an even EASIER fix would be to have the installer who did it, f do all that or find another, better ground point. LOL!!!
