Here's my equipment to be installed

2 8w7
C3 components
C2 dash
Alpine CDE-hd149bt
HD900/5

I need a box volume of 1.87 cu. ft. I've attached some pictures of my box shape but I wanted to double check my calculations. The whole measure twice cut once. I'll be using 3/4 MDF I can change all dementions except the lenght which is 31" outside or 29.5 inside. I really need the help.

I meant to add these will be down firing and here's the second pic it didn't upload in the first post. This is the shape of my box and its a sealed enclosure.

this wont give you a cut list, but it will help you when it comes time to actually cut the box. And its being hosted by a real DIYMA celebrity

It's hard to come up with something with only a single dimension. Here's an example though. If you're off by a few tenths of a cubic foot it's going to have no effect whatsoever.

That's what I was looking for, how did you calculate it? I had to do it in 3 parts but it's gotta be easier than that. Only difference between mine and yours is my bottom was 12" and my front was 8" (do to sub depth being 7" and needing 1" for the pole vent.

That must be a sealed box?

Is it a different routine porting a box like that? How would it be done?

Yes that box will be a sealed box, I have a small space to work with and a ported box for a w7 is big even for an 8.
