Recently had a new sound system put in, pushing out around 400w of bass.
Its sounding superb, but at times, with certain tracks I get a very distinct buzzing from the rear-view mirror. I know it's definitely due to the sound vibrations, as when I grasp it with my hand, the vibration stops.

Just wondering if anybody can suggest some sort of foam insulation or other deadener that I could fit to the mirror to reduce the vibrations, and stop the sound?


thanks.

pull the mirror apart and see where it's got movement , and rectify it.....not hard.
stick anything in there..

I had an annoying rattle from the mirror and it just needed the tek screw tightened

search function covered heaps of times

My mirror used to vibrate heavily with bass, but at around 50 to 55Hz it would actually buzz - very annoying.
I found that if I push the mirror upwards as far as it will go, that the vibration was less and the buzz is gone - this position either moves it out of the moving air or with the 2 ball pivots being at the limit of their travel, they hold position stronger.

HTH.

are you sure its your mirror? i have 2x 15'' subs in mine and the mirror doest rattle but the sunglasses holder did and also the whole plastic piece on the roof. i jus stuffed some spacers in there to stop it.
