Interior rearview mirror rattling/moving with subwoofer

Hello all,

Not a recall or TSB, but certainly annoying.

I just installed a 10" subwoofer and amp combo in my car last week, as I felt the OEM system was missing that low-end punch, and I'm a bass guy through and through, so I wanted to remedy that. First time I've had an aftermarket sub in one of my cars since '09, so I was really looking forward to it.

However, something annoying has popped up.

When the bass hits at a certain frequency, it rattles the FUCK out of the interior rearview mirror, to the point where the mirror moves out of position. To the point where I'll look at the mirror and realize I'm looking at the ceiling of my car. It makes a loud "buzzing" sound when it moves, as if it's loose on the "rod" that holds it to the windshield or something.

This means I either A) have to keep the bass levels lower than I want to, therefore not getting the punch I desire, or B) have to keep adjusting the mirror every 30 seconds to put it back to where it was so I can actually see behind me.

Now keep in mind I don't have the bass turned up to ridiculous, EXTREME levels, at least not in my opinion (this is subjective of course). But it's really annoying me; the moving AND the rattling/buzzing sound it makes when doing so.

Is there a way I can secure it better or do something to stop it from moving?

Anyone on here with aftermarket audio have the same problem? If so, have you developed a jimmy-rig or some kind of solution to stop this from happening? It's driving me nuts.

Thanks!
