i've tried searching all the threads and couldn't really find anything. i have a stock system and i'm getting a light buzzing noise coming from the rear speakers. i've tried adjusting all the settings and it still happens. any help on this would be great. thx guys. (dealership couldn't find anything wrong)

 

sounds like something is loose. you would need to pull of the panels to see if the speaker is loose. is the buzz more like a hum, or vibration?

 

it's more like a vibration, a very consistent one. happens moreso when i listen to the radio. hardly ever w/ cd's. it's probably an isolated problem since no else has had it. thx for the help, i'm gonna remove the panels and check the speaker.
