will this speaker box fit

[bck4more]

I was wondering if my under the seat speaker box that was for my 01 f150 extended cab fit in my f250 crewcab. Its a downward firing box with two 12's in it. I did have to install seat risers to make it work in my f150 and it fit perfect.

almost positive no. best bet custom box between front seats like I have. or flip your rear seat brackets so the seat moves forward a few inches and custom built box back there. yeah the key to all this is custom.
