My car makes a whinnig noise that raises and lowers with the cars rpm's. My son works on the electrical systems on military aircraft for the air force. he said its possibly the alternator spinning is whats causing that humming whinning noise... being picked by the audio system through wat he called a dirty ground... So its possible thats its a grounding issue....
