speakers??

[ApexIt]

Hey guys, i frequently play music in my car but I have come across a problem. Sometimes when i drive the car and/or have the radio or cd plater on, there is a buzzing sound that I hear that seems to be coming from the rear speakers. I noticed that when i turn down the volume, the sound goes away sometimes but other times it doesnt. I dont think that the speakers are blown out either. Can anyone shed some light on this situation? btw, i have a bose stereo.

I get the same thing in the rear passenger door speaker - right by my ear. It almost sounds like a loose wire creating static or something.
