Rear view mirror help

I was just wondering what all of you do about your rear view mirror rattling. Cause I got a billet one and evertime I crank my system up it just rattles until its pretty much vertical and my stock one rattled so bad I couldn't see out of it. Is there a mirror out there that won't jiggle so bad. Then again this may be a dumb question since bass is always going to rattle everything. Just thought I'd ask.
