Double cab subwoofers

I have a 2017 limited double cab. Is there a subwoofer box that will fit behind the back seats. I cant put a box under the back seats because i use the storage box.

 

Not enough room behind the seats

 

Any other locations besides under the back seats?

 

I fit one behind the seat. I had to custom make the box.. Its a pain to do.. I had to make the seat back flip down, then also space the bottom of the seat out by about 1". I used a shallow MTX woofer in about a 0.9 QBFT box. I have the box mounted on the left side. the box fits around the seat belt mechanism and belt.. The only issue i have, is that side of the back seat does not fully lift up, and it reduces the leg room back there by the 1". It's ok for me, as its mostly only my dog in the back seat.. I'm playing around with redoing it, making it fit the right side maybe and use storage space and the area up behind the seat. Maybe make it out of fiberglass...
