Does anyone have any sub box plans they can let me have a copy of? this is to hold a single 10" downfiring sub under the rear seat of a 2000 F-150 Lariat Supercab (half size back doors).

Looking for a sealed box that's about 0.5cf volume. Thanks.

 

Seat lift or no? How much mounting depth?

 

No seat lift, and not sure on the exact mounting depth. Would need to go measure it (can't at the moment) but it's basically the same truck as the one in your signature (as long as your rear seats fold up towards the seat back).

Mounting depth of the sub I plan to use is 5"

 

My buddies '00 has the same seats your have. I think there is about 6-6.5 inches under there if I remember right. We made a box for his pickup that held a sub 6.5 inched deep, and had to raise the back seat 3 inches.
I dont think your going to fit that under there without a seat lift...there just isnt any room under these seats without one...
