Hello Heavyduty, thanks for the response.....I did sand an area under the harness clamp at the frame neck. After sanding and tightening rhe bolt back up, it didnt help. I ran a dedicated ground right from the battery terminal with some wire and alligator clips to the amp ground wire terminal lug after that, still no go. I have the "Gain" setting just pass 1/2 (about 1'oclock) .
