I have for sale a sub box for ext cab Ford F150 it's a 2 12" box that is to go under the back seat. It will require raising the back seat a few inches to install sold the truck so trying to sell. Pretty much brand new never even drilled into to even install subs. Asking $50 call or preferably text 620-762-6177 for more info or offers. Would maybe consider trades of some sort.
