it isnt... never has been ... all of this started when i had two channels go bad on a set of 4ch rcas... just went and bought two sets of ground loop isolators is has deminished it but its still there and if i hook up ground wires on isolators its twice as loud as before.... //content.invisioncic.com/y282845/emoticons/rage.gif.0ad8a6e5565b5fddce406566fdd05149.gif lol tried grounding rcas to hu didnt work...
So your headunit is not grounded by the ground wire to your car chassis?
yeah but i never followed the lil black wire into the dash i wired at harness but other than that no extra grounds... so change stock location???
A ground wire grounded near or at same location as engine ground can produce engine whine.. Use a sheetrock screw or metal screw to create your own ground if the chassis runs behind your radio or near it.
will do... thanks
