So as some may have noticed watching any of my 3-4 videos I have pretty bad flexing on the top, well I took apart the top of the box and added a make shift internal brace, but after I put the top back on, screwed the box in, and did liquid nails wood adhesive around all the gaps I didn't put any glue/caulking on the width of the sides/front/back so now when it plays full tilt the wood "claps" or rattles against each other.
Should I try longer screws (using 1.5") woods about 1" thick. or attempt to add a threaded rod through the area and attempt to access the spare tire wheel well. I've added a plank of wood on the top screwing in the left right and middle of the plank, and also added an L bracket type steel plate screwed into the top of the box and the plank (about 14-18" long) and still vibrates full tilt.
