Sub Size That can Fit Behind Backseat of 2nd Gen. Double Cab?

Hello,
I'm new to the forum and don't know if this has already been asked but I'm trying to find the dimensions of a subwoofer box that would behind the backseats of a double cab with all the plastic removed. If anyone could let me know how much space there is to work with back there, I would greatly appreciate it. Or even easier, could someone tell me if either of these will fit? Thanks in advance for any help.

Option 1

Option 2

 

neither of those links show the size of the sub enclosure. I know that you have to watch out for the cross bar that run across the back of the cab. And there are child seat hooks that can also prevent you from mounting a box.

So you will probably end up having to remove the child seat hooks (i did) along with the plastic bins.

I have seen a couple people that mount slimline subs under the passenger/driver seat.

 

I think there are a couple companies that make boxes to fit properly behind the seats. With or without amp mount.

Personally, I run a Kicker 8" in box under the rear driver side seat. I pulled the tray out and fiberglassed a box in with a mdf board with the hole cut in it. I put the amp under the rear pass side seat.
