I'm having a problem with my LOC, i was getting a bit of static type noise through the speakers. I checked the manual and it said when this happens to hook up a ground wire to the chasis of the car. So I did that and now you can hear engine noise through the speakers, it is much worse! It happens even if I just hook it onto another wire that is a ground.

Is this what a ground loop isolator is for???

I should add that with the LOC grounded to the chasis and the car off there is no noise at all. without it grounded there is still noise.

Also, this explanatory link was in my copy buffer from another post. It has a nice explanation about what a ground loop is.

In your case, I'm not sure that you have a ground loop problem or just a bad ground.

Read all the excellent materials as "sticky" posts at the top of the car audio forum.
