      Description

      Give Your Stang Some Serious Bass. If you’re not feeling it from your Fastback Mustang’s stock audio system, it may be time to invest in some serious bass power. The JL Audio Stealthbox is a sealed enclosure design that simply fits in the location normally used by the optional Ford factory subwoofer. The built-in 12 inch subwoofer driver handles up to 400W, pumping out powerful, deep bass.

      All Fiberglass Construction. The Stealthbox is built from rugged, sturdy fiberglass, creating a sealed enclosure that is tuned to work in your Mustang. The front face is finished in a hard-wearing fabric that fits right into the trunk of your car. The enclosed 12 inch subwoofer driver features a cast alloy frame, rugged polyropylene cone, and long-lasting rubber surround.

      Installs Easily. The Stealthbox simply fits into the same place in your Mustang as the optional factory subwoofer. No drilling or cutting is needed. Any factory subwoofer must be removed.

      One-Year Limited Warranty. JL Audio provides a limited one-year warranty on the Stealthbox.

      Application. The JL Audio Stealthbox Subwoofer Upgrade Kit fits all 2015 to 2023 Ford Mustang Fastback models.

      Technical Note. If you have a Mustang that was not equipped with a factory subwoofer, you will need additional speaker wire to install the Stealthbox properly.
