am i the only one with this problem???? my mirror does not stay at the same place when the bass is pounding...how did you all fix this? i am sure there are bunch of people who's got bigger bass than i do hehe...

 

That's totally normal. People have been trying to "fix" it for years. People have even tried placing lead sheets behind the mirror. I don't know if they were successful. If you want something that might work try using heavy steel cable and secure three points on the mirror to points that will not vibrate noticably. But with the mirror grounded to three stable earth points you won't be able to drive far. At least not with the mirror.

 

It normal to have things shaking and vibrating when you got the bass hitting hard
