I'm trying to build a box for my 2000 ford ranger reg cab. I want 2 kicker 10's or 12's (the most I can fit). I know the 10's need at least 1 cubic foot of volume space and the 12's need 1.25 cubic feet so I'm not sure what I can do. Also, the 12s need 5 7/8 inch mounting depth and the 10's need 5 1/16.
Questions:
1. If anyone has any box demintions, I would greatly appreciate them
2. Should I chamber the box?
3. can i fit the 12s or am i stuck with 10s?

This is my first box but not my first car audio rodeo. Please speak slowly but not too slow. lol. Thanks in advance for helping the beginner.
EDIT:
The measurements that I got are:
Wall to wall (Only under rear speakers): 50"
from inside of rear speaker to inside of rear speaker: 32"
Speaker to floor room: 6.5"
Height of box wanted: 14"
Top of box to seat(comfortably): 5"
Bottom of box to seat: 8"

I included the speaker to floor dimensions because I want something like this: http://www.supercrewsound.com/99RangerStdDual.html

I would really like for somebody to draw up the dimensions that I need because I don't want to screw it up. Or any help at all.

If I were you I would build the box with a slope at the top at so your speakers go in at an angle that way you have more leg space in your truck and the speakers have room to breath instead of just blasting bass into your back seat

i went 31x11x7. easy box to build, fit between the speakers. I got 2 re audio Rex10D4 subs. they only need .35 cubic feet minimum .50 optimal. Mine has two chambers. It came out to about. 42 cubic feet per chamber using .75 MDF board. It hits hard and fits perfect. You can go one model up on the subs and they will still fit in the box. (Sex10d4)

Good luck.

Thanks, I decided to go with a 11x7x31 with the side chambers in the picture that goes under the rear speaker and get 2 shallow mount 10s. Still in the modification process but thank you for responding. I just can't figure out how to delete a thread. lol
