JL Audio SB-F-MUSCPE/12TW3 Mustang Enclosure



Stealthbox® for 2015-Up Ford Mustang Coupe

Compatible with Ford Mustang 2015 +

Ford Mustang JL Audio 12TW3

The latest all-American pony car gets a big dose of horsepower and major technology enhancements, all packaged in a new sleek and sexy body. Sadly though, the stock audio systems just can't deliver enough bass to keep up with the Ford Mustang's high-performance muscle.

JL Audio's Stealthbox® features an all-fiberglass, sealed enclosure design that fits in the same location as the optional factory subwoofer (and requires no holes to be drilled for installation). Equipped with JL Audio's revolutionary 12TW3 thin-line subwoofer, this Stealthbox® delivers deep, powerful bass that's worthy of your Mustang's heritage.

The Hard Data: Contains one 12TW3-D4 in a sealed enclosure. 400 watt power handling. Wired for 2 ohm mono. Installs in the passenger side rear corner of the trunk. Factory subwoofer (if equipped) must be removed for installation of Stealthbox®.


  • Note - Will not fit convertible models!

All W7’s, W6’s, TW5’s, TW3's, TW1's, W3v3’s and some of our ZR products. We also build our Marine Speaker Systems, Home Subwoofers, Stealthbox® products and the vast majority of our enclosed subwoofer systems in Florida.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. This commitment to state-of-the-art technology allows our highly skilled workforce to efficiently build JL Audio products to extremely high quality standards.While it is also feasible to build good quality products overseas (and we do build some of our products in Europe and Asia), it can be challenging when the product’s technology is innovative or complex. Since most of our premium loudspeakers incorporate proprietary, patented technologies requiring specific assembly techniques, we prefer that the people who design them have close access to the people manufacturing them.
