Well my RT Box that i bought from car toys came apart with my hugemongus 250 F*CKIN WATTS and car toys will not do anything about it! he told me to put some screws in there! well its a bandpass box...

ANYWAYS, do any of you know any sub box construction resources or can somebody fill me in on what makes a good box, i could car less about how it looks, i just want the most out of my system, i have 2 Fosgate HE's and a 200.a amp. I will cover teh box in that carpet stuff... its going in an e34 (89-95 5 series) my friend said none bandpass boxes work the best. I don't want to spend that much, no fancy stuff, just the wood type ones and caulk, BTW what kinda wood do you use? thanks in advance.

Car Toys what "a better way to go"! Well boxes are made out of MDF i like using 3/4inch, but here are some links that will tell you every thing you ever wanted to know and more.

Those bandpass boxes are hella dodgy, and Im speaking from experience. The one I had was made from chipboard and was very easy to pull apart.

As dallasdriver said boxes are made out of MDF, which can be picked up from nearly any hardware store. For building a sub box I would recommend anything thicker than 12mm MDF - and my current sub box was built out of 25mm MDF

Its a heavy bitch

Good luck with the construction

Yes, use 3/4" MDF. or for more strength use MDF and wrap it in two TIGHT layers of fiberglass. Make sure if you have two subs the are completely sealed from each other if you are using a ported or sealed box. Ordered or bandpass boxes are ok, but I prefer sealed. hard hit and with the right contruction and sub choice, low bass.

I actually use very little wood (1/2" mdf for the the bottom so it's flat on the floor and the sub ring is 1/2" as well) the rest is fiberglass with some carbon fiber.

Just for clarification... and to avoid the big waste of time that I went through, you want medium density fiber wood. Not particle board, which some stiff at a hardware store gave me. My fault for not knowing, but nevertheless.... the fiberwood is sawdust mixed with glue... one can get an amazing finish with it.
