Right sub box?

Small Hijack (apologies): As long as you have the box design program open for the OP, any chance you could for me as well? I've tried using a few of the box programs, but I'm not that good at it yet.
I'll thank you in advance & hope you have the time.
Requirements: Hard, Loud, clean bass. No rumbly crap, I hate it. Is there such a thing as a ported box that doesnt rumble?
Subs rated for 350 wrms each (have 2) Amp is PDX1.1000 rated at 1197 wrms.
Space: Up to 40" wide, 22" long, 24" high. A bit bigger on height / width is ok. I prefer a wedge so the subs are firing at a 45 degree angle instead of into the back seat (small SUV Ford Escape)
Mat: 3/4 MDF except for baffle, 1" there.
Specs:
DIAMETER: 12" (300MM)
SENSITIVITY (2.83V @ 1M): 92dB
POWER HANDLING: 350WRMS (1,400WPEAK)
FREQUENCY RESPONSE: 23 ~ 400HZ

Again, just in case you have time to do it, thank you.
