My amp just got back from dbr for a mosfet repair and the back plate seems to rattle violently still, even though they said they used loctite on all the screws. It flexes about 1/8th of an inch, is this something to be concerned about to damage anything? Ive tried alot of methods (stuffed towels in corners of amp, mounted dense rubber on mounts to absorb vibration) and minimized the rattling a little but it still flexes, especially on high notes. attached is a pic on how its mounted. Its mounted on birch wood on back of enclosure, 3 inches away from back of the trunk so im limited on space

Unbolt the amp, fold over a rag/hand towel a couple times so it fits snugly underneath the amp and reinstall it.

Dont mount it on your enclosure..try somewhere a little less violent.

I think theyre pretty neat. When the water runs down your crack as you let one out... its like shitting in a crockpot.

Just throwing this out there: brace your box more if possible. I usually mount the amp on my box and I try to do it directly over a brace - be it a 2x4 or a section of the slot port. And there is no noticeable amount of vibration coming from my box
