Our take on the JL Audio Stealthbox®

by Dominic Devito
JL Audio

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.

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 2007-up Nissan Altima Sedans. It installs in the trunk against the driver side wheel well. This Stealthbox® includes one 10", 2-ohm W3v3 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 a Sales 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.

Note: This Stealthbox® will not fit Nissan Altima Hybrid or Coupe models.

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 W3v3-2 subwoofer is loaded in this sealed enclosure and wired as a 2Ω load at the enclosure's 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.

Awesome Sub

Written By Franz D, South San Francisco, CA on Monday, April 16, 2012
Crutchfield Customer Review (What's this?)
 
I've had the Stealthbox in my '08 Altima since February 2012. And all I can say is WOW!! I kept the stock non-Bose head unit but I replaced all 6 six speakers with Inifnity Reference speakers with a JL Audio XD400. The sub complements the speaker upgrade I did. This Stealthbox is being powered by a JL Audio Slash v2 250 and it's just perfect.

Mainly I listen to jazz, r&b and hip-hop. Sometimes though, I play some good ol' Bass 305 and Bass Mekanik. the 10' sub holds it own and delivers lots of bass. I'm sure it's not any award winning SPL competitive bass but it's good enough for me. And I think my neighbors are already bothered by it... ;-P

Aesthetically, it looks great and best of all it does NOT take up space. =) Buy it and you won't regret it!
Pros:
- Awesome bass for any type of music - Space saver - Great conversational piece among friends
Cons:
Nothing really... except for the price if you compare it to what you can get But it really is a question of value and it has become very valuable to me.

Just what I needed....not too much, not to little, just right

Crutchfield Customer Review (What's this?)
 
At first glance, the high price of the JL box made me a bit skeptical if it was worthy of the $$$. But shortly after installation and me hearing it I was a amazed at the amount of bass it put out. I went from using two 12" Kicker Solobaric speakers in a custom built box paired with an Alpine MRP-M850 (800 Watt amp to power them) Which really pounded hard in my car.

Down to just this one JL 10" 3v3 in the Stealthbox and paired it with the JL Audio Slash v2 Series 250/1v2. (which is the recommended amp if you look at the stealthbox installation directions) And can honestly say that, this sounds just as good as those 2 speakers did.

This one JL stealthbox: gives full sounding, deep resonating bass, that I feel is just the right amount. Not overbearing and definetly not under performing. I was also a little worried about the amp only being 250 watts and the stealthbox is rated to take up to 500 watts, but the directions from JL stating to pair this amp with this speaker were spot on! And the Best part of it all is I have now regained full use of my trunk space and I am one happy camper.
Pros:
What I really about this product is it gave me my trunk space back. It is a great space saving design, that tucks away neatly behind your left rear wheel in the trunk. And although the stealthbox is small it packs a huge punch for being just a Single JL audio 3v3 10" and doesn't compromise sound quality.
Cons:
I really don't have anything to complain about except the Price is a little steep for 1 subwoofer in a molded enclosure, even if it is designed specifically for your vehicle. Only other thing I would say & this is nit picking is according to the directions you don't have to remove the left rear wheel to finish the mounting of the box, You may not have to remove the left rear tire but it makes the install a heck of a lot easier.
