PaulO2288 Posted November 19, 2007 Report Share Posted November 19, 2007 It seems like their maybe something wrong with your head unit. Just check these also to elminate any problems that make the noise that can make the humming noise also. Are your rca's and power wire ran on the same side of the car? Also check your cars grounds to make sure they are secure and have a good clean metal contact!!! Link to comment Share on other sites More sharing options...
