I just got a 2002 F250 from my company for a work truck/personal vehical. I desperately need to upgrade the stock system.

However, it's a standard cab without much space at the rear so I'm not sure at all what kind of box/sub combo I should get.

Does anyone have any thoughts on good low profile subs, probobly 10", and how to go about designing a box for the very small space?

Thanks!
