Making strong box
I'm making a subwoofer box for my son's truck. Space is an issue so I'm going to put the box under the front seat. I'm using 1/4 inch Birch for the box, and want to strengthen and stiffen the wood. I have two products that I use quite a bit, and would like your opinion on best one for this project. The first product is LiquidWood and WoodEpox. I have used these products exclusively on rotted or cracked wood previously, but think they might be good here. The second product is 2-part epoxy resin and maybe fiberglass cloth. Both the LiquidWood and resin soak into the wood, though the resin will form a hard shell.
Does LiquidWood strengthen good wood? I like the way it work on rotten wood, but do not know if it helps otherwise. I prefer to use the LiquidWood because it is easier to work with and I think it will give better sound than a resin finish. The Birch is not strong enough on its own, at least not at 1/4 inch, and anything thicker will not give the cubic feet of space necessary for the subwoofer to operate.
Your comments and suggestions are most welcome.
