Why Choose JL Audio SB-T-4RNRG5/10TW3 Stealthbox System?

Built in U.S.A. with Global Components
At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.
Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. The following JL Audio products are built in our Miramar, Florida factory, with global components:
•Subwoofers: W7, W6v3, TW5v2, TW3, TW1, W3v3
•Enclosed Car Subwoofers: Stealthbox®, PowerWedge™, ProWedge™, H.O. Wedge™ & MicroSub™ Enclosed Subwoofers
•Marine Loudspeakers, Marine Subwoofers and Marine Enclosed Loudspeakers
•Home Subwoofers: Dominion™, E-Sub, Fathom® and Gotham®
Installs Behind Factory Panel
The 5th Generation 4Runner has been long-overdue for a Stealthbox® solution. When we finally approached the challenge, we knew owners cared about the vehicle's cargo space and we didn't want to interfere with OEM cargo slides or aftermarket cargo drawer systems. The result is the addition of a spectacular 400 watt, 10-inch subwoofer solution tucked nicely behind the factory cargo panel. The Hard Data: Contains one 10TW3-D4 subwoofer in a sealed enclosure. 400 watt power handling. Wired for 2 ohm mono. Installs behind factory panel in the passenger side rear cargo area. Subwoofer is protected by the included black steel mesh grille and concealed by a fabric grille. Installation requires permanent modification to the factory panel. Installation in models equipped with an "OEM" subwoofer require purchase of a standard factory panel from Toyota Parts. Will not fit models with third row seating.
Frequently Asked Questions (FAQ)
- • Which Toyota 4Runner models is this Stealthbox compatible with?
This model is custom-engineered for 2010-2024 Toyota 4Runner vehicles. It is not compatible with models equipped with third-row seating.
- • Where is the enclosure installed, and does it take up cargo space?
The unit installs behind the passenger-side rear cargo panel. It is designed to stay out of the way, ensuring no loss of cargo floor space and no interference with OEM cargo slides.
- • What do I need to do if my 4Runner has a factory OEM subwoofer?
You must permanently remove the OEM subwoofer assembly and purchase a standard non-subwoofer factory interior panel from a Toyota parts dealer to house the Stealthbox.
- • Does the installation require permanent modifications?
Yes. Installing this Stealthbox requires permanent modification to the factory interior cargo panel to ensure a proper fit and finish.
- • What are the power handling and impedance specifications?
It houses a 10TW3-D4 subwoofer rated for 400 watts RMS. It is internally wired to present a final 2-ohm mono impedance load to your amplifier.
- • Can I use my factory head unit to power this subwoofer?
No. The factory system lacks the necessary power to drive this subwoofer. You must use a dedicated external monoblock amplifier to achieve optimal performance.
- • Is the subwoofer protected from cargo damage?
Yes, the system includes a rugged black steel mesh grille that is concealed by a fabric grille, protecting the woofer cone from shifting gear or trail equipment.
- • Why is secure mounting essential for this installation?
Proper mounting is critical to prevent the enclosure from shifting during vehicle movement, which avoids both safety hazards and significant degradation in bass performance.
