Does not Fit

This box does not fit a 2014 Ford F150 Super Crew under the rear seat. The rear seat will not go all the way down when the box is installed. The box ends will fail when someone sits on the rear seat.

Seems ok

1st off, this is built pretty good I think, about the same as my last box in a 2002 chevy. So build is decent to good. Let's talk space. I am no expert, but not sure it's .8 cubic feet. (That's what my other box was, it was a bit bigger.) Mounting depth is not 6 1/4!! My 5 15/16 deep sub hit about an inch short from fitting. I did find a good sub top fit, jl audio 10inch, depth is almost 5 inches. Haven't got yet but should drop in. I assume, the box will sound fine. It does fit under back seat, barely. It sticks out about 1 ta 2 inches if you want the back seat all the way down, no biggy there.
I'd buy again. Just need to change the specs!

Good box

The box fits and works good in F150 Supercrew. Good value

2015 f150 10" sub box

The box looks great and is built very well. My only complaint is the carpet seam is on the front of the box and with traffic in and out of t he truck the front will occasionally get hit and now the carpet is coming off. I will re-carpet it when I find some black carpet that matches my interior. I also dont car much for the big shinny BBox emblem but it is hot glued on so dont bother trying to remove it. This box is recommended for a 09-14 f150 but it seems to fit very well in my 2015. I would have given it four stars if the carpet seam was in a different place.
