Double baffle will do alwmost nothing for you
Bracing it was keep that box stiff if you ask me ( and Ive only ever used big boxes )
A 2X2 8' can be bought for 2 freakin bucks, and just make a brace up and down on your sub baffle, and left and right to the sides, BUT connect the 2 braces with a few screws for even more strength
Ive built 15+ cube boxes out of 1/2" MDF single baffle with just some 2X4 braces and on 3000+ rms and 4 15's, held just fine with NO flex
