I just got a 04 crew cab, and i took the old audio system from my old truck and i want to install it in my 250. My problem is i have no where to put the subwoofer. Has anyone ran into this problem? any help would be appreciated.

 

Behind the back seat, 2 shallow mount Pioneer 12s

I've seen a few custom boxes that mount inside the center front seat if you have a 60/40/60 which hold a full size 10. Anything larger and it pretty much cant be done unless you just want a big box sitting in/on your back seat.

My amp mount under the back seat cut to fit inside the factory storage tray:

Looks a lot cleaner now, that pic was kind of the mock up shot

 

I dunno if this helps, but i had a custom box put under my seats and it holds 2 10" memphis subs...but then again I do have a supercab... I'll take some pics tomorrow and post em up, so you can see if you'd like

 

Here's the box I bought for my 05
