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 contains one 13" TW5-3 subwoofer. It installs under the driver side of the rear bench seat. 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 low. You should be able to install this enclosure if you have any experience with car 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.

Has Issues

Written By JakeH, Charlotte, NC on Friday, October 31, 2014

Came with large chips/chunks of loose fiberglass rattling around inside. I took it apart to find wiring broken. Had to rewire inside, not to mention vacuum fiberglass clips from insides of speaker. Upon placement in truck, doesn't fit perfectly. Rear seat won't go back down 100%. So now, I am going to have to take my seat apart and trim the metal in the seat so the box fits. Pretty poor manufacturing from JL Audio.

Pros: Should sound good if I ever get it installed and working.

Cons: Poorly manufactured.

Crutchfield Customer Review (What's this?)

Have had this in my truck for a couple weeks now and it really hits hard and clear.

Thanks for your question. In general you will want an amp that will supply about 600 Watts RMS at 3-ohms. For information on comparing amps I would recommend reaching out to an Advisor by phone or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Jeff  Dec 23, 2013 ]  Staff
I forwarded your question to an Advisor and they responded with the following: That amplifier will not work with this Stealthbox as it is only 4 ohm stable in bridged mode. The JL subwoofer runs a 3 ohm impedance If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jul 01, 2014 ]  Staff
splice remote turn on from factory amp [ ROD  Feb 27, 2014 ]
