To Note

Ground loop isolators are considered a band-aid, as they suppress a problem that was created during installation. The only true way to fix the problem is to find the cause of the noise and eliminate it. Sometimes running the power wire down one side of the car and the RCA cables down the other will fix the problem. Another common cause is from using power wire that is too small for the audio system.
