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 2002-up Dodge Ram trucks with 40/20/40 split front seats. It replaces the center seat cushion but retains the factory storage tray feature and armrest surface. This Stealthbox® includes one down-firing W3v3 13.5" 2-ohm subwoofer from JL Audio. 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 or high. Crutchfield recommends using a car audio professional to install this enclosure, unless you have extensive experience installing car audio gear.

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 13" 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.

JL Audio Stealthbox®

Written By Anonymous, Jacksonville, FL on Monday, October 06, 2014
JL makes fantastic products. I personally have a double 12" ported box, and JL makes solid, flat response enclosures that go down to 20 Hz. For home theater applications, they make sealed subwoofers that outperform many ported competitors. American engineering at its finest. I don't own JL home audio as it is a little pricey, but in the consumer pre-built stereo speaker market, you really can't find a better value, as custom applications will always prove more expensive.

i'm giving it 2 stars because i just haven't lived with it long enough. The JL sub I had before was a MUCH tighter bass sound.But this thing looks fantastic in my truck. It goes LOOOOOW!!! I have the SW ouput set at -10 and its still a lot.Also, if you are used to your SW being behind u in a trunk, u WILL be very surprised at how different it is to have it up between the fronts. I may need to tweek my settings to get it where i want it, cuz right now it doesnt totally work for me.
SUPER DEEP BASSSSSS!!!! U will not be disappointed.

worth the money

Crutchfield Customer Review (What's this?)
I waited quite some time before finally breaking down and spending the money for the JL sub&box. Wished I would have done this a long time ago the sound is unreal, I hit lows I never have with any other set of 12's. Would highly recommend to anyone looking for hard hitting bass. I powered mine with a T400-2 fosgate amp and it supplied the perfect power needed.

I am pushing the JL 13.5 Stealth with a JL 500/1and let me say I have friends pushing three 12s that can't even come close do hitting bottom like I do with 1 JL sub. If you have the opportunity to go the extra mile and experience this combination, DO IT! This product is worth every penny.
Extremely happy I bought it.

JL Audio Stealthbox®

Written By Allen, Topeka Kansas on Saturday, April 25, 2009
Just had a JL Audio Stealth Box installed two days ago. After a year in a half of waiting ,I decided to go with this one. Although it's costly ,it's worth every penny! If you are looking for sound quality you can not go wrong! This thing sounds "AMAZING." I have a JL 500/1 pushing the 13.5 sub. It hits every bass note from high to low with "INCREDIBLE EFFICIENCY." Special thanks to the staff at Crutchfield and Jose the tech at JL Audio for steering me in the right direction.
