SB-F-SUPRDTY/10W1v2: Stealthbox® for 1998-2008 Ford SuperDuty Trucks with 40/20/40 Split Front Bench Seat

Ford's SuperDuty trucks sport a completely unique interior design, requiring their own Stealthbox® models.

The Stealthbox® replaces the center seat cushion of the front seat for trucks equipped with the 40/20/40 front bench seat. The factory upholstery then covers it for a totally stock appearance. A down-firing 10-inch subwoofer in a sealed enclosure is precisely matched to the truck's acoustics for impressive sub-bass performance.

The Hard Data: Contains one 10W1v2-4 in a sealed enclosure. 300 watt power handling. Wired for 4 ohm mono. Replaces the bottom-center seat cushion of the front seat. Stealthbox® must be covered using cover from the bottom part of the factory front center seat. Will not fit F-150 trucks. Will not fit models with bucket seats/console. Stealthbox® is not as comfortable to sit on as the factory seat cushion.

"If you're lucky enough to have a vehicle that one of these Stealthboxes is made for, choosing it over anything else we have heard or seen is a no-brainer."

– CarSound Magazine

"...I was only hoping for more bass to the tune of what the factory Shaker 1000 system offered. What the JL Audio Stealthbox delivered was performance that surpasses the factory Ford stereo systems so completely that you can’t even compare the two systems."

– Shane McGlaun, I4U News, November 2010... on the Ford Mustang Stealthbox
