Vehicle Compatibility
This JL Audio Stealthbox® is engineered specifically for the 2022+ Toyota Tundra CrewMax, delivering powerful, space-saving bass that fits cleanly under the rear seat.


⚠️ Not compatible with hybrid engine models.

 

High-Performance 12" JL Audio Subwoofer
Inside the Stealthbox is JL Audio’s 12TW3-D4, a premium thin-line 12" subwoofer designed for tight spaces without compromising output. Featuring a mica-filled IMPP cone and durable rubber surround, this sub delivers deep, clean bass while maintaining long-term reliability. The system is wired to a 2-ohm mono load for optimal amplifier performance.

 

Advanced JL Audio Technologies
Concentric Tube Suspension (Patented)
This innovative suspension design allows the woofer to maintain full excursion capability in an ultra-shallow form factor. By relocating the motor inside the large-diameter voice coil, JL achieves big-speaker performance in places where a traditional sub simply won’t fit.

 

Dynamic Motor Analysis (DMA)
JL Audio’s proprietary DMA technology ensures:

  • Reduced distortion
  • Stable motor force across the entire excursion range
  • Clean, accurate bass even at high volumes

The result is tight, articulate low-end that enhances any music style.

 

Floating Cone Attachment Method (FCAM)
FCAM provides superior alignment of the cone, surround, and voice coil assembly. This increases linearity, improves excursion control, and ensures long-term performance you can trust.

 

Custom-Molded HDPE Enclosure
The Stealthbox enclosure is constructed from rugged, sealed HDPE for maximum durability and long-term stability. The molded design ensures:

  • A perfect, vehicle-specific fit
  • Zero rattles or resonance
  • OEM-like integration under the rear seat

This is a true plug-and-play upgrade engineered to disappear into your interior while transforming your sound.
