Hello,
I was wanting to install a sub box for a 10"in the back of a 99 dodge ram 1500 extended cab..I do not want to give up the tray under my back seat so i wanna put one in the back in the middle of the driver and passenger seat..I know a custom one would cost about $230.00 maybe?any help would be appreciated.

I would go with a hotbox that replaces the center seat. I had 2 10s under the rear seat and even though the hotbox is only one sub it sounds far better. You also still retain the functionality of the seat.

I have a box that fits under the seat(in the back, of course) that holds 1 12" if anyone is interested???
