speaker box dimensions for behind seat

[rocketBox]

I was wondering if anyone know the dimensions for a speaker box that would go behind the seat & rest on top of the in-cab gas tank? I'd like to stick some 6x9 speakers back there & was wondering if anyone knew these dimensions offhand.

Have no idea , but was thinking of stuffing some custom speaker boxes into the empty spaces on either side of the gas tank in the cab. Food for thought.

I can send you measurements of mine and pictures

It takes up all of the space of the oem fuel tank but also obstructs easy access to the stock bench seat and seatbelt bolts holes.

Mounts 2 10" subs in sealed boxes (too small an airspace for ported) and 2 large pioneer amps. you could easily modify design to mount(2) 8"subs
plus (2) 6x9's all in separated sealed boxes... my original plan

There is also space in the corner cavities for 4 1/2" round speakers in separate boxes... what I use now


Truck is at body shop right now so no installed pics for now
