hi in my gf KC laser whenever i turn the lights on it make a buzzzzing noise and i get alternator whine its not the amp cause i got a 3.5 to rca and played off portable mp3 player, fine but am really stumped with where it is getting in
the earth of the pioneer head unit goes to stock ground
i checked to make sure in head unit area the illumination wire is not getting pinched and not contacting even still when i had the head unit connected and just holding it, it still made the noise when i turned the lights on, the engine doesnt need to be on
any suggestions at all thx
