I made all of the boxes I have ever had in my cars.

First, you need to find out the recommended enclosure volume/per speaker. Usually for a 12" sub, the enclosure volume should be as close to 1 cubic foot as possible. Obviously, 12"x12"x12" may not always fit into your physical design, so what you do is alter the dimensions to be different, but ultimately have the same volume.

So it will take a little playing around with the numbers to get the optimum dimensions for your "wedge" design so that you can maintain the desirable volume. The spec sheet should also tell you the recommended enclosure type (sealed, ported, etc...) Its a little work, but it will pay off.

Usually all the info you need to get optimum performance is right on the spec sheet that comes with the speaker. Infinity are great speakers and should have more than enough info to work with.

Good Luck!:D
