Right now I've got each of my 3 momos in separate boxes, and they take up most of the space in the back of my s-10 blazer. So, I decided to make a box to put all three in so that they would give me a bit more room. Well, I started making the box out of some mdf I found in the garage, and while I was putting some of the pieces together, I thought "that wood seems kinda thin." Anyways...turns out, the wood is 5/8" thick instead of 3/4". Is this 1/8" difference going to cause any problems in the end? It went together pretty solidly, and seems to be quite sturdy, but I don't wanna end up putting the subs in that box and have it fall apart on me. Another thing is, I'm gonna do some fiberglass work on it as well, would I be able to reinforce the box with fiberglass if we conclude that the 5/8" mdf alone would be too weak? Any comments or suggestions would be helpful. Thanks much.
