If so, it is possible that it is your Alternator. When one or more of the phases fail, due to a fault in the Windings or the Diodes, it can make the sound you describe. If not, most stereo noise is a Ground Issue. Check all the Grounding points as well as for chafed wiring which may be going to Ground. Absent both of these, you may have a problem with the Amplifier or Head Unit. Hope this helps... Happy Motoring!...Jim'99
