Getting back into car audio... Need some help with my box

[ladi3sman55]

First off I have been out of car audio for a few years now. I recently bought a 96 Yukon and finally have more room than what i did in my neon! Anyways Ive never had this much room to work with and would like some help designing a box. I have some dimensions and a few ideas for what i want to do but not sure how they will work out.
First off i have roughly 22 cuft of room to work with (leaving me with room to see behind me and room for misc crap and groceries) I have a single Mach 5 Audio SPL-15 that will see ~1000 watts from my Cadence Daytona amp. Im looking to get low but still decently loud. Probably going to tune around 30hz.
I guess my question is how big should i make the box? Should I utilize all 22 cuft or is that just over kill for what I'll be doing? I'm not looking to change my sub/amp setup (unless someone wants to trade my 15 for something?)
