Its for my brother he has a 2002 mitsubishi montero sport. The dimensions that I can use are 21" in high, width 34" and depth is 34". Id like it to be sub back and port back. The sub box I would like it to be 6cu ft and tuned to about 32hz. I can only do for free so it can just be simple. 3/4" mdf

I told best buy that nobody would give me a box design and take like a couple minutes out of their time so they said i can go get a prefab tomorrow.

20" high 28" wide 25" deep will give 6.67 cubes before sub and port displacement
be right around 6 cubes after displacement

ok what happens if the length of the port is cut 2 inches to short, so instead of being 22.18 it is 20.18. Should i get another peice and cut it to 22.18 or is 20.18 ok?

I'm not one to make someone feel bad dude, but no body did this because they feel sorry for you. And trust me, no body believed that you were getting a box for an 18 at Best Buy LOL!

It's gonna be tuned a little higher, it all depends on what you want. A lot of car audio is trial and error. I didn't even know there was a forum when I first started out and I'm better for it.

The best buy thing was a joke I didnt want to say bump so I just made something up so my topic would go back up to the top before it went of the first page. So your saying I should just go for it and see what happens?
