: help (high pitched sound)

01-29-05, 03:56 PM

I have a 1993 Cadillac Seville with a Delco Bose Gold Series Dolby B NR stereo. When i turn the stereo on, I hear a high pitched ringing sound. I Checked to see if it was all 4 speakers and it is, so it doesn't appear to be the speakers. Anyone have any suggestions???

Thank you

Hi Michele,
With the stereo ON, accelerate the engine. Does the sound increase its pitch likewise? If so, most likely you have "engine noise". You will have to check your groundings. Do a search here, there are useful threads about it.
