Product Description

JL Audio SB-GM-4GSUVCNSL/10TW1 Stealthbox for 2015-Up Full-Size SUV – 94644

JL Audio SB-GM-4GSUVCNSL/10TW1 Stealthbox for 2015-Up, the fourth generation full-size SUV from GM gets all-new, luxurious interiors, along with major enhancements in performance and technology. Unfortunately, the stock audio systems continue a track record of weak bass reproduction. There also isn’t much room for a conventional subwoofer design, without compromising people and cargo space.

To neatly solve this problem, our engineers have designed a subwoofer solution that installs invisibly, inside the factory console, with zero loss of console storage space.

Featuring 100% fiberglass construction, this Stealthbox® is equipped with a down-firing 10-inch TW1 thin-line subwoofer in a sealed enclosure design.

The Hard Data: Contains one 10TW1-2 in a sealed enclosure. 300 watt power handling. Wired for 2 ohm mono. Stealthbox® installs inside forward-most portion of front center console, without affecting storage space or cup holders. Replaces the OEM “subwoofer” system, if vehicle is so equipped.


JL Audio’s Miramar, Florida loudspeaker production facility is one of the most advanced in the world.

At a time when most audio products are built overseas, JL Audio’s commitment to in-house loudspeaker production continues to grow. To pull this off in a competitive world market, our production engineering team has created one of the world’s most advanced loudspeaker assembly facilities and established a global network of quality component suppliers who build to our specifications. This, combined with our commitment to state-of-the-art assembly technology, allows our skilled workforce to efficiently build JL Audio products to extremely high quality standards, right here in the U.S.A.

Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we find it is vital that the people who designed them have close access to the people manufacturing them. The following JL Audio products are built in our Miramar, Florida factory, with global components.
