You might be able to fit the speaker there but, there will not be enough air space. that speaker requires a good amount of air space to work and sound good. your better off putting 2 10" subs under there. Rockford (P3shallow) and Alpine (type S and type R shallow)make some good shallow subs. Audio Enhancers make a good box for that truck, you can get it with a bed liner type finish or carpet.
