Ive done:
rca grounding on head unit.
swapped rca's
grounded head unit and amp at same spot
shortened amp ground to one foot or less
If i remember correctly i did not have whine until installed inline fuse before fuse block or swapped amp? could it be one of these?//content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
