JL Audio Stealthbox® for 2010–2024 Toyota 4Runner

Premium Bass. Zero Clutter. Delivered by Trail Grid Pro.

If you want deep, powerful bass in your 4Runner without giving up valuable cargo space, the JL Audio Stealthbox® is the ultimate upgrade. Engineered specifically for the 2010–2024 Toyota 4Runner, this enclosure blends seamlessly into the factory interior while delivering the tight, clean, hard-hitting bass that JL Audio is known for.

Engineered for Perfect OEM-Style Fitment

JL Audio spends months designing each Stealthbox® to guarantee two things:

  1. It fits your Toyota like a factory-installed component.
  2. It produces superior bass performance compared to universal enclosures.

Their engineers analyze interior contours, acoustic behavior, and factory mounting points to determine the ideal shape and location for the enclosure. The result is a stealthy, factory-like installation that preserves your interior layout while dramatically boosting low-end performance.

Hand-Built Fiberglass Construction

Each Stealthbox enclosure is made from rigid hand-laid fiberglass, offering:

  • Superior structural strength
  • Low resonance for clean bass output
  • More internal volume compared to wood
  • A perfect, form-fitted enclosure that disappears behind your factory panel

JL Audio craftsmen laminate, grind, join, and finish every Stealthbox by hand in the USA, ensuring unmatched quality and consistency.

Custom-Fit Bass for Your 4Runner

This Stealthbox installs behind the factory panel on the passenger-side rear cargo area of 2010 - 2024 Toyota 4Runners (excludes models with 3rd-row seating).

Loaded With:

  • One JL Audio 10TW3-D4 10" subwoofer
  • Wired for 2-ohm impedance
  • Handles 400W RMS / 800W peak

The 10TW3-D4 is one of JL Audio’s most popular thin-mount subs—delivering exceptional low-end output and accuracy while fitting into extremely tight spaces.

Important Installation Notes

  • Installation requires permanent modification to the factory panel.
  • 4Runner models with a factory subwoofer will need a replacement OEM panel from Toyota.
  • Not compatible with 4Runners equipped with third-row seating.
  • Trail Grid Pro can help verify compatibility before you order.
