Big Bass, Minimal Space — Delivered by Trail Grid Pro

If you want deep, powerful bass without sacrificing valuable cabin room, the JL Audio Stealthbox® is the perfect upgrade for your Toyota Tundra. Each Stealthbox is engineered for a specific vehicle, shaped and tuned to blend seamlessly into your interior while delivering the signature JL Audio sound—tight, clean, and incredibly impactful.

Engineered for the Perfect Fit

JL Audio spends months developing every Stealthbox to ensure two things:
1. It fits your vehicle like a factory-installed component.
2. It sounds better than any universal or generic enclosure.

Their engineers determine the ideal shape, mounting location, and internal volume for each application. Then, they load the enclosure with the perfect JL subwoofer(s) to match the design, delivering maximum output without sacrificing clarity or musical depth.

The enclosure itself is made from hand-laid fiberglass, providing exceptional rigidity while allowing more internal volume than wood. This gives you louder, deeper bass from a stealthy, space-saving design that looks like it truly belongs in your truck.

Custom-Fit Bass for Your Toyota Tundra

This Stealthbox® is designed specifically for 2014 - 2021 Toyota Tundra CrewMax models and installs cleanly behind the rear seatbacks.

Includes:

  • Two JL Audio 10TW3-D8 10" subwoofers
  • Wired for 2-ohm mono
  • Handles up to 800W RMS
  • Sealed fiberglass enclosure for tight, accurate bass

No permanent modifications are required. However, you’ll need to remove the factory subwoofer (if equipped) and relocate the factory jack tools during installation.

If you’re not sure about fitment, Trail Grid Pro is always here to help confirm your setup before you order.
