I've been looking at threads all day. Found many excellent posts. Still havent found 100% sure setup that will work for the '13's (or I have and dont know it). This is my first ford, always been a chevy owner.
Here's the deal:
1. I dont want to raise the seat
2. I'm install 2 infinity kappa perfects needing .75ish f^3.
3. Amp mounted on back of cab wall
4.I don't care if they fire down/up

Has anyone actually built an MDF box that would fit this setup?

 

What size are the speakers? What's the mounting depth? Is that .75cf per speaker or total?

Listing those detail will help people be able to tell you whether it's possible or not.

 

thanks for the reply!
The subs are Infinity 104.7's (now discontinued).
Specs from crutchfield at http://www.crutchfield.com/S-TY61Wsb...ml#details-tab

Top mount depth 4 13/16"
Bottom Mount Depth 5 3/8"
Infinity recomments .75cf per sub

Ive been looking at this, and cant really figure a way that its even possible

 

If you can get some dimensions of under the seat I might be able to draw up a rough sketch of a box for you if I can get a design that works for them! All I'd need would be the height at the front and the back of the seat, depth, and max width.

 

These are the outside measurements of the box I built for my brother's '10 Screw:
H1: 8.5"
H2: 6"
D: 12"

Width will have to be figured out to get the proper airspace...

As much as I hate to recommend prefab boxes that would work perfectly haha.

Or if you want to build your own you can just rip off their outside dimensions ha.

 

ditto.

 

I broke down and ordered a Fox Box from foxaudio.com .. By the time i bought all the materials it really wouldnt have saved me THAT much to build. Plus I do really like their design.
Will post pics when i get it in.

 

Materials would've costed roughly 35-50 dollars. And with there box being tuned to 36hz be careful with songs with really low bass, it can bottom out the sub. Also that box is about 1cf under what those subs want to be ported.

 

Wow, with that much room (increase depth 1 inch) you could stuff 2 SI Mag V4s under there.

*kinda wishing I had a 09+ LOL* (but still love my BMs)
