Perfect sound to go with the perfect fit

JL Audio puts months of research and design into each Stealthbox® custom-fit subwoofer to ensure not only that it fits, but that it sounds better than any other custom enclosed system. First, JL Audio determines the ideal shape and mounting location for each enclosure, so that it looks like an original part of the vehicle it's designed for. Next, they mount each high-performance subwoofer so it delivers amazing firepower from within its unique enclosure, without sacrificing clarity or musical depth.

JL Audio Stealthbox installed

The fiberglass enclosure offers superior rigidity while allowing more interior volume, so the sub can turn out louder, deeper bass. JL Audio craftsmen then laminate, grind, join, and finish each Stealthbox® by hand. The end result: full-bodied, distortion-free bass from an impressively stealthy enclosure.

Enjoy enhanced, custom-fit sound

This Stealthbox® enclosure fits 2011-up Ford Explorer models. It installs in the passenger side rear cargo area (factory sub will need to be removed, if equipped). This enclsoure isn't compatible with the cargo security shade accessory. This Stealthbox® includes one W3v3 10" 2-ohm subwoofer from JL Audio. A steel-mesh grille is included. Please check with us before purchasing by using the vehicle selector on our site, or calling an Advisor at 1-888-955-6000 to verify fit information.

JL Audio has rated the difficulty of this Stealthbox® installation as moderate. You should be able to install this enclosure if you have experience with car audio, but some vehicles may require modifications.

Product Research


Overview: JL Audio's Stealthbox subwoofer systems are designed to hide away in a specific vehicle. Please consult "Outfit My Car" to confirm compatibility with your vehicle.

Construction: Stealthboxes are hand-crafted from fiberglass and/or Advanced Molded Composite (AMC) materials. Fiberglass delivers a level of enclosure rigidity and dimensional stability not possible with other enclosure materials, allowing wall thickness to be reduced compared to a typical wood enclosure. This gives you more interior box volume for a given external volume. Fiberglass and AMC materials are very strong and can be molded into very complex shapes; giving JL Audio the ability to design your Stealthbox to fit perfectly into tight spots and minimize intrusion into your vehicle's useful space. Each Stealthbox is laminated, ground, joined, and finished by hand in the USA. Proprietary techniques and materials developed by JL Audio through years of fiberglass manufacturing experience ensure consistent quality and performance.

Woofer: One 10" JL Audio W3v3-2 subwoofer is loaded in this slot-loaded enclosure and wired as a 2Ω load at the enclosure's post speaker terminal.

  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W3v3 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.
  • Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.
  • Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.
  • Spider/Lead Wire Assembly: The W3v3 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.
  • Elevated Frame Cooling: The elevated frame design of the W3v3 delivers high-velocity air flow through slots directly above the top plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.
  • Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.

is this single voice coil or dual?
justin  Mar 03, 2023
1 answer
Greetings Justin, and thank you for your question. The W3 JL subwoofers are single voice coil. Either 2 ohms, or 4. This one is a single voice coil 2 ohm.
hogan  Mar 08, 2023 (Staff)
I have a 2020 Explorer with one of the two B&O packages. The website is saying that it doesn't fit, despite it saying it's made for explorers. Maybe it's because of the B&O package. Does anyone else have this installed with that package?
joe  Sep 05, 2022
1 answer
JL Audio only lists this enclosure as working in Explorers from year 2011 to 2019. At this time, there is no listing for a Stealthbox that will work in the 2020 or newer Ford Explorers. If that changes, we will update our web site to show the compatible model.

will u still be able to put the 3rd row seats down in a 2018 ford explorer?
mikey  Jan 03, 2022

Yes, it's doesn't hit the seats. It's got about an inch or so gap. Just make sure you drill hole and mount it to your car.
kris  Jan 03, 2022
Yes is the only box on the market at this time that will allow third row to work properly. Nick Harper 2018 Ford Explorer
nick  Jan 03, 2022
I have a 2017. The way the box is set up now it does rub slightly. It does not load the seat motor and I don't believe the amount of contact made between the seat and the box will cause any significant amount of wear over time. At least for the amount of seat manipulation that I do. I did tighten down the box retaining bolt a little more from where I initially had it. I could go back in and tighten a little more, but I am happy with installation and what I consider to be a minimal amount of contact.
todd  Jan 03, 2022
Absolutely, this doesnt hinder the seat controls at all, they did a great job designing this, seats go up and down perfectly!
timothy  Jan 03, 2022
Yes, but it could rub a little. Not enough to load the motor. I can't imagine really any damage from rubbing over time either. I tightened the box retaining bolt and that sucked it in. I could go back and tighten it more and be fine but Im happy with where it is as described above.
todd  Jan 03, 2022
Yes , it just clears it
anthony  Jan 03, 2022
What is the volume of the box?

We have not received any answers from other customers on your question. I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They should be able to help answer your question.

Can I just order the box?
linnell  Sep 13, 2018
1 answer
I'm afraid JL Audio doesn't offer any empty Stealthbox enclosures for separate purchase. For more details or to discuss other options for your vehicle's system please contact an Advisor directly by phone (888.955.6000) or online chat.
david  Sep 18, 2018 (Staff)
Do you make a box that fits on the drivers side or does this box fit on the drivers side? that way i can install 2 subs one on each side.
josh  Dec 09, 2017
1 answer
It's not possible. The only reason this one works is because you cut out the passenger storage compartment (there isn't one on the drivers side).
chris m  Dec 09, 2017

looked on line for a dealer
vernon  Oct 06, 2016
No. I purchased an Alpine MRV- 500. The box does not come with an Amp. Great sub!!!
tamill  Sep 26, 2016
Is there an option to color match the interior?
jeremy  May 02, 2016

While JL Audio often offers the Stealthboxes in an assortment of colors, this one is only available in the single color shown. I hope that helps! My Bio:

Are these JBL stealth boxes amplified or do they need a separate amp for my 2014 Ford Explorer XLT?
chuck  Dec 07, 2014

You will need an amp. Just the box and speaker.
dan  Dec 07, 2014
Thanks . Is there a plug and play kit to install it withthe factory OEM system?
chuck  Dec 07, 2014
Hello Chuck .. I have this in my 2014 Explorer and it does need an amp to run it. This is not a powered subwoofer. I use a Alpine mp500 I believe ... Hope this helps. HAve a great day
