Is This Box Do-able in a Reg Cab S10?

I picked up an Audiobahn aw1251t and a few other pieces on trade a few weeks ago and am looking to put in a 1998 reg cab s10. I've found plans for a box that will give me the correct volume according to what I have found on the sub, but I'm not sure that it will fit due to the mounting depth. This is my first attempt at adding a sub to a vehicle and also my first attempt at building a box. If I'm able to mount it in the box, I know that it will have to be as low as possible. Here is the box I'm looking at building. Seems pretty straight forward. I'm only asking this because after searching, the last mention I found about the audiobahn was 4 years ago. If someone has had experience with this please let me know.
