Cannot hear it while driving even with stereo off. But at stop quite noticeable. A rrrrrRRRRRRRRRrrrrr whining sound. My guess is the alternator. But is it just getting wierd or is it getting ready to DIE!!!! With the lights off the noise is almost imperceptible. Just curious. ???? One beat'99 Tropic Green SVT

Try checking your grounds or your gains on your amp (if they are turned up to high you get wine) and a bad ground will also cause this. just my two cents 96 teal contour nothing yet but im saving

Another possibility is scored commutator or worn bearing that allows rotating element to contact the field coils & generate the whining sound. Replace alternator.. OR... could it be a low fluid level in the power steering pump reservoir?...just my $00.02. Is the smoke alarm in your house also known as the "dinner bell"?
