The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.
Perfect sound to go with the perfect fit
JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.
The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.
Enjoy enhanced, custom-fit sound
This Stealthbox® enclosure fits 1999-up Ford SuperDuty trucks with front 40/20/40 split bench seats. It replaces the center seat cushion of the front seat and the factory upholstery covers it. This Stealthbox® includes one down-firing 4-ohm 10" W1v2 subwoofer from JL Audio.

JL Audio has rated the difficulty of this Stealthbox® installation as moderate or high. Crutchfield recommends using a car audio professional to install this enclosure, unless you have extensive experience installing car audio gear.
Note: This Stealthbox® enclosure will not fit in the F-150 or in models with bucket seats and a center console. And though it's a visual match, the Stealthbox® is not as comfortable to sit on as the factory seat cushion.
