Features

Vehicle Compatibility: JL Audio's SB-J-JL4DPAS/10TW1-4 Stealthbox has been specifically designed to fit the 2018-up Jeep Wrangler Unlimited. It mounts above the passenger side rear wheel-well and won't affect installation or removal of the vehicle's hard-top. A driver side version is also available. The enclosures for either side can be used individually or as a pair for even more bass.

10-Inch/4-Ohm Woofer: The SB-J-JL4DPAS/10TW1-4 Stealthbox features a single 10" JL Audio 10TW1-4 subwoofer in a custom sealed enclosure The 10" 10TW1-4 subwoofer offers a powerful combination of a shallow mounting depth and high excursion capability, producing deep powerful bass from a small enclosure. The single 4 ohm subwoofer is capable of handling up to 300 watts RMS and includes a sturdy steel mesh grill for protecting the driver.

• Concentric Tube Suspension: JL Audio's patented Concentric Tube Suspension employs a molded structure which spans beyond the edge of the motor structure, supporting the spider on the outside of the motor's boundaries and the large diameter voice coil on the inside. The large voice coil permits the magnet to sit inside it, rather than surrounding the coil as is typical in most woofers. The concentric tube structure and the elimination of a conventional top-plate helps JL Audio place the motor higher up into the cone body's space to further compress depth, while still permitting excellent mechanical excursion.
• Mica-Filled Polypropylene Woofer: The subwoofer features an injection-molded, mica-filled polypropylene cone with a rubber surround for added durability, excursion and bass response.
• Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 10TW1-4 motor remains linear over a long excursion range, and also maintains a stable fixed magnetic field in the gap over a wide power range. The result is reduced distortion, faithfully reproduced transients, and tight, articulate bass.
• Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Enclosure: The Stealthbox sealed enclosure is made from 100% fiberglass and finished in automotive grey carpet. The enclosure has been configured to mount over the passenger side rear wheel-well. A matching trim panel and sturdy steel-mesh grille are included, so you can carry plenty of gear without worrying about damage.
