Single 12-Inch 2-Ohm 500-Watt Subwoofer-Enclosure for Select 2009-UP Dodge-Challenger
This reborn American legend just might be the most faithful interpretation of the classic “muscle car” formula to date.

JL's Stealthbox® for the Challenger is the perfect product to begin your audio transformation. It installs neatly into the driver-side corner of the trunk with minimal impact on usable cargo area. Spectacular sound quality and impressive output are delivered by a high-performance JL Audio 12-inch subwoofer in a sealed enclosure precisely matched to the Challenger's acoustics by our engineering team.
Great audio in your Challenger begins here.
The Hard Data: Contains one 12W3v3-2 subwoofer in a sealed enclosure. 500 watt power handling. Wired for 2 ohm mono. Installs against driver-side wheel well. Stealthbox® includes a steel-mesh grille to protect the driver. Access to the spare tire, jack and tools remains unaffected. Installation requires removal of factory-installed ‘subwoofer' if vehicle is equipped with ‘Kicker® SRT® Audio Package'.
Stealthbox® products are built to order and generally ship within 5-6 business days of receiving your order.

Single 10-Inch 2-Ohm 400-Watt Subwoofer-Enclosure for Select 2021-UP Large Chevrolet and GMC SUV Vehicles
GM's fifth-generation full-size SUV gets all-new, luxurious interiors, along with major enhancements in performance and technology. Unfortunately, the factory audio systems still lack quality bass reproduction. There also isn’t much room for a conventional subwoofer design, without compromising people and cargo space.

Featuring 100% fiberglass construction, this Stealthbox is equipped with one of JL's innovative, 10-inch TW3 thin-line subwoofers in a custom-formed, sealed enclosure.
The Hard Data: Contains one 10TW3-D4 in a sealed enclosure. 400 watt power handling. Wired for 2 ohm mono. Stealthbox® installs behind the driver side cargo trim panel. Replaces the OEM “subwoofer” system, if equipped.
