i just pput my system in and i love it. but when i turn it up it shaked the mirror soo much that it faces it straight down. does anyone have this problem and is there anyway to tighten the mirror, or what have u done to stop this.

Turn the bass down. Just kidding. Mine moves a lot, but doesn't go down and saty there. Try something like a dab of silicone so it stays felixble, but holds.
