sound system issues (bad ground maybe?)

DONE

put the dash back together, cd player in the lower slot, monitor in the upper

no more whine either! new RCAs helped some, new ground helped some (thanks biju) then i added an inline noise filter in the power to the HU and that seemed to get rid of the rest, during heavy acceleration its just barely audible, not at all when theres music playing

i think the 3rd wire is for ur amp power signal, but if it works for u gj

yeah, after doing some more research i found out they were for remote turn on, so i just taped them off, the upgraded wires definately made a difference though
