Where can I find a good box?

[ccm0012]

I'm getting a 02 F-150 SCrew Lariat! I already have 3 Alpine Type R 12's and I wanna put 2 in there! Does anybody know where I can find a Box that will fit and that has room for deep subs, and will look good?
Thanks,
Clint

i hope your not looking to go under the seat, and since your not going to have any luck with under the seat than i would say custom is the best option

Custom that will go a little ways under the seat but will stick out a good bit and have the 12's facing the front???
