Double Cab sub enclosure cross section advice needed

*first time trying to attache an image to sorry if it doesn't come through*

I drew this up today and was hoping that some of you who have built this in that past could look at it and tell me if my numbers seem right. Any thoughts or suggestions would be MUCH appreciated as i plan on building and installing this weekend.

 

Figured out the pic... standing by for advice. thanks guys and gals.

 

i just put my box in the same spot last weekend except for notching that wall i just cut that crossmember off lol seems to be pretty close to what i did

 

Cutting the cross member sounds WAY easier than putting a crazy notch in the box... i think i might go that way... how did you secure it to the back wall of the cab? or is it just held in by the seats?

 

mine is just sittin there right now the dimensions were down to a millimeter the way i wanted to them so its very snug i will be making sometype of bracket thought to mount it to the back wall

 

You also have to consider all the little tabs on the back for the plastic bins... gotta make little indentions for those too.

I cut off the rear bar, cut off all the plastic attachmetn points, and used the outter shell as a trim piece. Much more airspace that way... bolted box to floor.

 

I'm likin where you guys are going with this... a little big of metal demo and a standard box with no little nuances... thanks for the help!

 

The top of my box is 3" and it doesn't hit the seat. All other measurements seem to be similar to mines. I can install a 10" sub that is a little more than 5" deep with a magnet that is approximately 6" in diameter.

 

just when you cut on that back wall watch the spot welds if your not careful you can rip then right out i did with one of them by accident so i just welded a spot back on cant even tell also painted over it lol
