I finished securing my sub box the other day, and when I had screwed in the top angle brackets, it started vibrating when ever there was bass. I unscrewed them and it went away, so I thought it was the brackets. I added a little dynamat to them and a good sized square on the metal outside the truck just behind where the box is and that didnt help. I dont know what to do, so Id apreciate any help. Sorry for the quality of the pics, my digital camera is a piece of crap. Thanks
My sub box.
This is a close up of the angle brackets I used to secure the box with.
Just because I don't say it, don't mean I aint thinkin it.
