JL Audio Stealthbox® — Delivered by Trail Grid Pro
Big Bass. Zero Clutter. Perfect Fit.
When you want powerful, clean, low-end performance without losing valuable cabin space, the JL Audio Stealthbox® is the ultimate subwoofer solution. Each Stealthbox is engineered specifically for your vehicle—shaped, tuned, and hand-built to blend seamlessly into your interior while delivering the kind of bass JL Audio is known for.
Engineered for Your Toyota — Not “Universal”
JL Audio doesn’t guess when it comes to vehicle-specific bass. Their engineers spend months researching mounting locations, acoustic behavior, and enclosure shapes to ensure every Stealthbox:
- Fits like a factory-installed component
- Delivers deeper and louder bass than generic enclosures
- Preserves cabin space and functionality
- Looks clean, OEM-like, and unobtrusive
Once the design is finalized, each unit is loaded with a high-performance JL Audio subwoofer chosen specifically for that enclosure. The result is big, authoritative bass that stays musical, accurate, and distortion-free.
Premium Construction, Built by Hand
Every Stealthbox is crafted using rigid fiberglass construction to maximize internal volume and eliminate unwanted vibration or flex. JL Audio’s craftsmen laminate, grind, and finish each enclosure by hand—resulting in a beautiful, stealthy enclosure that disappears into your truck but transforms your sound.
Unmatched Factory Fitment
This Stealthbox installs behind the rear bench and features:
- One shallow-mount 13.5" JL Audio 13TW5v2-4 subwoofer
- 4-ohm total impedance
- 600 watts RMS / 1200 watts peak power handling
If you’re chasing even bigger bass, two Stealthboxes can be installed behind the seat.
Notes on Fitment:
- You’ll lose one “click” of rearward seat adjustment, and the seat must be slightly forward to fully recline.
- If your Tundra has a factory JBL subwoofer, you will need to trim the factory panel or order a “no-subwoofer” panel from Toyota.
- JL Audio rates this installation as moderate—DIY-friendly if you’re comfortable with car audio, though some vehicles may require minor modification.
Trail Grid Pro is always here to help confirm compatibility or answer additional questions.
