I just purchased an 03 f150 single cab a few months back. I was wanting to know if you guys have a link, or some info on what type of sub box will fit in a single cab f150. Im not looking for any big and fancy, single 10 or 12..

 

I'd pick a subwoofer first, sonething that doesnt have a huge mounting depth. Then build a box to the woofer's specifications that will fit behind the passenger seat.
