I have a problem with my door mirror glass shaking when I drive. When I have the stereo turned up it's impossible to see anything behind me. Just wondering if there was any way to tighten them up.

 

If you are talking about the glass in the mirror head, then the only thing you can do it check to see that all 5 points are pushed in.

If the center locker is not connected, it will be really loose.

If you tilt the mirror glass to the door, then take a small light and stick it back in the mirror head you can see if the center connector is in all the way.

If you are talking about the mirror head, then you take the interior door panel off, and check the 3 bolts on the mirror head itself.

If if is not either of these, turn down your stereo, you are damaging your hearing with that much bass

 

dude... look at all of those amps and subs! A friggin Rolls Royce would vibrate loose with that much stereo at loud volume.
