I was in a rush to finish my box and i forgot to add bracing. I usually mount an amp to the top of the box but it flexes so much even with the amp screwed down it makes a lot of noise from vibrating. The box is around 4 cu ft. would it be enough to glue one or two pieces of mdf scraps that are about 2 inches thick to the top and bottom of the box? Would the glue be enough to hold it becaus the box is already in my car and was a pain to get it in so im just going to take one sub out and glue the bracing in.
