I've been looking around for some info on anyone that has put 15in subs in a single cab truck. Right now I have 2 Memphis dvc subs in custom single boxes at 1.3 cu.ft. apiece. I know it's possible but looking for box ideas. Thanks in advance.

 

I can't help with that, but Pioneer is making an amp/subwoofer in a single unit that wood fit nicely under the seat so you don't use up all the space behind the seat.
