I build this underseat box for 6.5s and 8s, the box construction is MDF, The subs are inverted and the box is ported.
The box is built to match your subs or whichever subs I recommend for the space.
I build for stock seat height.
Base Price: is for an empty MDF sub box (see variants).
Shipping is per box (gotta weigh the big girl first)
This box is made to look like Ford built it themselves and wanted it to slap.
No square corners and no acrylic windows.
