I want to build a 6 cubic foot ported enclosure for one 18" the enclosure will be going in to my 2001 oldsmobile alero. Anybody have a suggestions or have built one before! (plans)

I have only built a few small sealed boxes in my time.

the box size i came up with is 24"x24"x24"

Tank you in advance

Using 3/4 inch material, a box with those outside dimensions would have an internal volume of 6.5 cubic feet. Can you fit an enclosure of that size into the trunk of that car?

How big is a box that measures 24x24x24.... ? it certainly is not 6 cu.ft

Am I THAT bad with math?

with 1" material. it's 22" x 22" x 22" internal volume, minus sub displacement and port displacement, but barring those two things, is 6.16 ft^3.

However, I've never seen a 2' high box fit inside a alero.

I must be THAT bad too. I had to do the math, thinking it was going to be huge, 8 cubic outside dimensions, then when you think about it, around 3/4 sheet of material. Using 3/4 material it was 6.5.
