The JL Audio Stealthbox® custom-fit subwoofer delivers incredible bass in a package that takes up minimal space and blends in with your vehicle's interior. JL Audio designs Stealthboxes to fit in specific vehicles, then loads them with appropriate subwoofers for optimal performance. Pair the system with an appropriate amp and wiring for stellar concealed bass.

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.

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 2004-06 Scion xB Generation 1. It installs under the passenger side front seat. This Stealthbox® includes one 10" 4-ohm W1v2 subwoofer from JL Audio. Please check with us before purchasing by using the vehicle selector, 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.

Vehicle-specific enclosures with subs? Say what?

Instead of the usual sub in a box, the manufacturer creates a molded enclosure that fits perfectly into a convenient spot in your specific vehicle, housing a high-quality sub. Some enclosures even include a built-in amp, for the ultimate in stealth bass. The advantages? You don't lose much space (if any), your sub is perfectly matched to its enclosure, and your enclosure has a factory look that won't tell potential thieves you have an awesome sound system. Doesn't get better than that.

Features

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 W1v2 subwoofer is loaded in this enclosure. The woofer is rated at 4-ohm and wired in inside the box for a 4-ohm mono load at the enclosure's speaker terminals.

  • Surround Stress Relief: By creating a radius 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.
  • Interlocking Cone & Dust Cap: The W1v2's utilize a dust cap that is not just glued, but also interlocks with features molded into the cone body for a tight snap-fit. This creates a more rigid cone assembly and a more reliable dust cap attachment.
  • Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W1v2 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: The Vented Reinforcement Collar (VRC) is a composite structure that addresses two issues related to reliability.
    • Stress Relief: By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes
    • Air Flow: The VRC also features slots that facilitate air flow directly onto the voice coil windings. This reduces thermal compression effects and enhances reliability
  • Insert Molded Suspension/Coil/Terminal Sub-Assembly: The W1v2 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. This type of assembly ensures precise lead wire length, lead wire entry and exit angles; and coil to spider perpendicularity.
  • Elevated Frame Cooling System: The elevated frame design of the W1v2 delivers cool air 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.

Exceeds my expectations greatly

Crutchfield Customer Review (What's this?)

So, I finally bit the bullet and bought one of these and I am so glad I did! This is 150% exactly what my sound system needed. This little sub can peacefully fill out the missing sound spectrum from my lightly upgraded system, OR it can vibrate the heck out of everything not properly secured/dynamatted in my xB. This sub is capable of hitting harder and lower than full size 12" Alpine subs I had in a previous vehicle. If my ears serve me right, I got good consistent volume down to about 28Hz.

For the longest time, I had been toying with the idea of fabricating a box to tuck under my passenger seat, possibly out of MDF or fiberglass. To anybody considering that option, you really should just save up the money for this little guy. I installed it under my seat in about 15 minutes (including removal and installation of the passenger seat). ...Save yourself the headache. Buy this. Now.

Pros: Very high build quality Great sub/box pairing creates crisp clean bass (or can be turned up to 11 to deafen you) Easy to install -- Only requires a 14mm wrench and a drill Perfect fitment, really maximizes the space available under the passenger seat. You won't mind the price after you buy it. Wire clips are very sturdy. Carpet matches my interior perfectly. Surprisingly lightweight.

Cons: You literally need to drill 2 holes through the floor of your car to properly secure the box. I tried driving around with it unsecured and it slid around a lot. Also the holes where the threaded rods go are open to the inside of the box, so you need to seal those holes if you don't bolt it to your floor. ...As I live in the rust belt, I smothered the entire area around the holes I made in my floor with Toyota seal and then sprayed undercoating liberally around the holes I made to prevent rust

Thanks for your question. For information on selecting the best amp for your subs I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences between the amp models and help you make the best choice for your system. [ Krissy  Aug 04, 2014 ]  Staff
