TLEJ Posted June 24, 2010 Report Posted June 24, 2010 When I turn my car on, my subs bump. When I like.. Turn the volume up or down, with no input.. the bump every level it's turned. When I turn my headlights on, they bump. But it's VERY slight.
baaudio Posted June 24, 2010 Report Posted June 24, 2010 Could be a poor headunit ground or amp ground. I would check both of those Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k

J-Lane Posted June 24, 2010 Report Posted June 24, 2010 Try grounding the head unit to the frame of the vehicle instead of using the factory head unit ground. They are usually inefficient.
