Space behind seats in supercab

[DRock]

Hey friends. I am new here on the forum with a question. I am getting a 2004 Ranger Edge supercab with flareside bed. I have a large collection of car audio equipment and I would really like to put at least three of my Kicker CVR 15" subwoofers behind the seats. It would really really help me out if i knew the dimensions of the space behind the seats in a supercab (extended cab) ranger. I am pretty certain I could build a box to fit the dimensions some how some way but I dont know what space I am working with. Could someone take some pics with a tape measure for me or tell me how much room there is back there? That would be absolutely great. I am trying to get all of this accomplished before I get the truck so I can drop everything into place and be done. This truck will be entered into a car show and competing in all areas of audio and time is an issue right now.

I won't be able to get you photos any time soon, but if this helps any:

The diagrams are crazy, but the table clarifies them some.
