Im looking to possibly repair my box? i just had this box built, its for 2 xv3 18s. i was having a problem at first where i was blowing the lid off the top of the box so i went through and put screws dipped im wood glue every inch of the box and that seemed to work for now. but now the inside of the port has broke off from the top lid. i was thinking i do the same thing all the way down the port? i dont know if thatd cracked the wood or not tho, its 3/4 birch plywood, everywhere else of the box is double baffled.

 

Its like this on both sides, this side is worse though.
