    I'm told I shouldn't ground my amp or head directly to the battery. Is that true?

    I was talking to a guy at an audio shop and he told me I shouldn't ground the amp or the head unit directly to the battery. He said it can cause ground loops, and he said there were a few other problems with doing that as well, I just don't remember them. I told him I have a mid-engine car with the battery up front, and that I figured I could just run the ground wire to the battery since it was so close. I was also under the impression that running to the negative terminal of the battery would PREVENT ground loop, not create it.

    He did say to run the power cables for the head and amp directly to the battery. I already knew to do that one.

    So should I just run my amp and head ground wire to a good contact spot on the chassie?

    Thanks for the 411

    i dont know about causeina ground loop....but you do want the ground as short as possible, reistance decreases with length so you have a great flow of power and less of a hazard. I am sure you could have problems such as a ground loop, but there are many ways that that comes about.
