2006-2016 Ford Super Duty SuperCrew Sub Box Power Glass and Seat Belt Sealed Recessed JL TW3

This is a Ford Super Duty SuperCrew Sub Box for the 2006-16 F250 and F350 trucks. Ford Super Duty SuperCrew F250 and F350 trucks don’t have a lot of options. Space behind the rear seat is at a premium and under the seat is not much of an option. For 2006-16, the boxes are 60.5×16.25×7.375 and the rear wall carpet must be cut to fit. This box has cutouts in it to fit around the rear shoulder seat belt and does has the cutout for the rear power window motor. There are also recesses to fit around the vents on the back wall for extra mounting depth. It is 1.67cuft shared airspace. The carpet on the back wall must be cut out for sub box to fit. It is a snug fit and may be easier to install with the rear seat unbolted. For trucks with the rear shoulder belt, the plastic covering it can be trimmed down and fits nicely back into place. If you need anything special feel free to ask.

This Super Crew enclosure is designed to work with JL TW3 10s and 12s. The JL TW series of subwoofers are shallow, but they stick out from the enclosure more than traditional woofers. If we didn’t recess the woofers they will get shoved into the back of the seat and damage them. This setup works very well with two or three 10TW3s or two 12TW3s. To recess the subwoofers we secure an extra piece of wood on the back of the baffle to give a 3/4″ recess to protect the woofers.

This is a sealed subwoofer enclosure. Sealed subwoofer enclosures have a tight and punchy bass that is more articulate and more true to the music with a more natural sound. For customers who want louder, deeper bass with the lower bass more pronounced, a ported enclosure is what you want. Because of the ported design, the bass will not be as tight and punchy, but there is typically double the bass of a sealed box with the same subs and power. If big bass is what you want, then our ported designs will be what you want.

This box is made out of 3/4″ MDF and is fully carpeted in matching carpet. The nickel plated spring loaded speaker terminals are mounted on the back of the box and the speaker wires are soldered on for a solid and reliable connection.
