How do I make a wedge box?

[Based]

I am making a ported box for a 15" subwoofer for the back of my hatchback (fiesta). I have almost enough airspace in the hatch area but I need like half a cubic foot of volume more so I'm thinking of making it like a wedge box.

For example, the "main" section will be 35W*13D*22H. Then there will be a wedge section on top of that. Obviously they will be all one piece but I'm just trying to convey what I'm talking about.

Anyway, how do I make it? Like how do I cut everything at the correct angle so it all fits?

Cut your side pieces first. You can then use the side piece with the angle to adjust your table saw blade accordingly.

Yeah I know how to design it I just don't know how to cut it/glue it.

Design I could see but the cutting and gluing isn't bad ... you can do it.
