Stealthbox® for 2019-Up (Gen 4) Chevrolet Silverado / GMC Sierra 1500 Crew Cab Trucks and 2020-Up 2500 / 3500 Crew Cab Trucks

This generation of Chevrolet/GMC trucks is bringing new levels of interior refinement and technology to the full-size truck segment. Our Stealthbox® enhances all this by adding impressive, high-quality bass without losing any of your precious people space or interior functionality.

The Stealthbox® slips under the truck’s rear seat and features two of our revolutionary 12TW3 thin-line subwoofers, giving you absolutely stellar sub-bass impact and quality. We even left a perfect spot in the middle of the enclosure for a clean, hidden amplifier installation!

The Hard Data: Contains two 12TW3-D8 subwoofers in a down-firing sealed enclosure. 800 watt power handling. Wired for a 2 ohm load. Installs under rear seat. Will not affect the folding of the rear seat or rear leg room.

Built in U.S.A. with Global Components

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

Detailed Information:
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:

  • Subwoofers: W7, W6v3, TW5v2, TW3, TW1, W3v3
  • Enclosed Car Subwoofers: Stealthbox®, PowerWedge™, ProWedge™, H.O. Wedge™ & MicroSub™ Enclosed Subwoofers
  • Marine Loudspeakers, Marine Subwoofers and Marine Enclosed Loudspeakers
  • Home Subwoofers: Dominion™, E-Sub, Fathom® and Gotham®
