2018 Double cab SR5 sub options?

Hey everybody. I'm sure after some digging through threads I could find answers to this question. But, what are some good options for a double cab sub? I have a 2018. With the XP package. I'd be willing to give the the under seat storage in the back to put a sub in there. It's a pretty small space, even on the driver side, which is 2/3's of the back seat. I have an amp i can install under the driver seat. And, an aftermarket head unit with sub pre-outs.
I guess what I'm looking for is an enclosure for a sub under the back driver seat. Google just had way too many search results.
Thanks in advance, folks. Enjoy your weekend!

They don't even make those any more.

 

Yeah they are pretty solid. JL makes good stuff.

 

@tech12volts builds top quality boxes. Mine with a single 12 fills the driver side under seat area. Can also do a pair of tens.

 

When I had my 2017 Double Cab.
Best Buy low profile Pioneer 10” sub box laying flat in cargo tray under seat only uses one side of the cargo storage tray under drivers side rear.

 

I have a pair of BNIB JL 10TW3s for sale if interested.
