I just had a 12" kenwood dub installed and the rear view shakes like crazy. What would be a good way to fix that? Even without the sub, stock speakers, it shook a little.

Thank you in advance

 

Learn to drive without looking at the woman mirror. I don't even use the rear view mirror except to hold my Valentine 1 hadwired radar.

 

Turn the bass down.........lol. I have a 10" sub in my truck and it will shake. Who cares..............crank them tunes.

 

Does it shake loose enough that you have to adjust it? I have two JL 10" subs hooked up and it's loud enough to make the car parked next me's license plate rattle, but my mirror stays in place. Of course it shakes enough it's blurry but there's nothing you can do about that but turn off your bass. As long as it's not moving the adjustment arm when it's shaking it doesn't matter. If that's shaking it's probably loose and you should fix that. If you're just complaining about the glass shaking... then you probably haven't ever had a decent sound system.
