I'm trying to design a vented enclosure for 1 Sundown SA-8 v1.

It will get 400w and is going in my 2001 BMW 530i. I want it to fire through the ski pass in the back seat (as seen below). The angle is 115 degrees. There are a couple holes in the rear deck lid to direct the vents through if that will help with sound quality.

My max dimensions are 32" wide x 15" tall x whatever depth necessary.

I modelled it in WinISD and got a 0.5 cu.ft box tuned to 32hz with a 3" diameter vent x 35" long (vent mach 0.8)

From all my reading this sub does well in a 1 cu.ft vented box. Did I model the box in WinISD wrong?

I tried getting RAM design a box for me to no avail.

I'm willing to pay $25 for a design that fits my needs.

1 cubic foot is a bit on the large side for these subs. I wouldn't go any larger than .75 cubic feet and feel free to save yourself some port length and tune at 35hz instead of 32. It will still get plenty low with a 35 hz tune.

 
I haven't finished it yet but I will be using PVC pipe.

I didn't go with the 2" for the same reason. Thought it would be more likely to whistle.

I'm going to do a small DIY flare on the PVC as well.
