my rear bose speakers the ones mounted next to the rear window i guess they are the woofers? well they annoy the **** out of me when i turn the bass up too high, its like something is loose in there and it makes this buzzing noise like something is shaking. do you guys know how to stop that buzzing? the speakers are fine its just when the bass is high they make it shake lol

 

it's the dust cover on them. take the rear deck off and super glue the dust covers and you'll be golden
