How can you get a sub box in an older truck with no extended cab? Just the driver seat and passenger seat then the bed right behind it with no room behind the seats.

either build a box or take it to a shop and have them build one room between the seats??
Put the speakers behind the seat. Most full size trucks, you can fit a couple of 10″ and span the box the full width of the cab to get the correct box volume. Depending on the truck, you may be able to fit a sub under the seat as well.
A friend of mine put 2 10s in his mid 70’s Chevy, and I was able to build a custom box and put 1 10 under the seat in a 70 Chevy pickup I had, but there was more room than normal under the seat and no seat lift.
I have fit 4 12″ subs in a chevy s-10 standard cab with adequate airspace. There is a really cool trick to it, but it is time consuming, and you have to work with fiberglass. I charge lots of $$ at my shop for that!
You may be able to find some stuff online about it. Some people call it a 5 sided box, or california box. You basically build some framework with 2×4’s and MDF liquid nailing and screwing it to the framing and back wall of the truck. Then you use fiberglass matting to line and reinforce the box cavity. Then you make a baffle board out of 2 layers of MDF, countersinking the subwoofer.
Once you are done carpeting, it is a permanent structure, and it looks like the factory would have put it there!
Oh yeah… it POUNDS!
On a small truck, I would stay at 2 to 3 12’s. Four was tough. On a full size, 3 or 4 12’s or even 2 to 3 15’s, no problem.
