JL Audio TW3 in 2nd Gen

Has anyone stuffed three (3) JL Audio TW3 12" subs in a 2nd Gen Taco (behind the rear seats, sans the plastic storage pieces)? With a 3.5" molunting depth and .80 cu.ft. requirement for a sealed enclosure, I'm wondering if they would fit. I'm sure they would fit with respect to the mounting depth, but the .80 cu.ft. requirement is where my curiosity lies. Thoughts on fitment and meeting required enclosure specs?
I've surfed through various threads and have seen single and double sub enclosures but nothing with three. Something similar to this, but with 12" TW3 subs (these pics are for 8" or 10" subs):

 

it is technically possible yes

 

No.

You can't even fit two. Not at .8 cu/ft each.

 

with minor modifications its very close , and with the use of 1/2 inch birch ply. Optimal is 2.4cf but you can most likely get away with 2.1-2.2Cf or less with some stuffing. It will be a very tight box but should work. @ZMan2k2 has 2 shok triton 12s in his box which i believe is also over 2cf or very close to it

 

I'm planning to purchase a 3rd Gen Taco in the coming months, and I hear that the rear seat/storage area is identical in size/dimensions as the 2nd Gen. I'll bring it to my guys once I get it and let them get a gander. Any info I can gather beforehand is greatly appreciated. Thanks for this and any other info that can be offered.

 

"Trapezoid" the notch as well (if you aren't removing baby anchors). This will buy you a 1" to 1.5" shorter box.
