About the JL Audio Stealthbox®
The JL Audio Stealthbox® custom-fit subwoofer enclosure 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.

More details on the JL Audio Stealthbox®
Vehicle Compatibility: The JL Audio SB-D-5GRAMCCF/12TW3 Stealthbox is specifically designed for 2019-up Ram 1500 Crew Cab trucks with a fixed rear seat. This Stealboth slips under the truck's rear seat and will not affect the folding of the rear seat or rear leg room.

StealthBox Construction: Constructed from 100% fiberglass with a rugged, weatherproof finish, this JL Audio Stealthbox includes all the mounting hardware needed for a secure, great sounding installation. The Stealthbox even has an perfect spot in the middle of the enclosure for a clean, hidden amplifier installation. JL Audio's Stealth box delivers impressive, high-quality bass without losing any of your precious people space or interior functionality.
Dual 12" Woofers: The SB-D-5GRAMCCF/12TW3 Stealthbox contains two JL Audio 12TW3-D8 subwoofers in a down-firing sealed enclosure. It can handle a 800 watts of power and is wired for a 2-ohm impedance load. The 12TW3-D8 subwoofer features an injection-molded, mica-filled polypropylene cone woofer with a rubber surround for added durability, woofer excursion and bass response.
- 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.
- Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method of improving dynamic motor behavior. As a result of DMA optimization, the 12TW3-D8 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, clean, 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.
Hardware & Terminals: The JL Audio SB-D-5GRAMCCF/12TW3 Stealthbox is outfitted with binding-post terminals and comes with mounting hardware.
