I have a 12" clarion 500w rms sub in my trunk. It sounds great but the bass rattles my car to much. Every 3 minutes or so i have to push my rearview mirror back onto the mount as it is rattling loose and will fall down in matter of minutes if i dont push it back on. Since their is no screw on these mirrors is there a way to make them stay on mount better? I would love not having to worry about my mirror falling every 5 minutes or so. I dont want to tape it or do something that would look tacky or be really noticeably visible. Any suggestions?
