Adding a subwoofer is the single, most significant improvement you can make to a UTV audio system. Not only do you get the benefit of the subwoofer's superior bass performance, but with proper system design, you also relieve the smaller main speakers in your car from the burden of reproducing bass. This makes them sound better, cleaner and louder.

In the tight confines of a side-by-side, there isn't a lot of room for a bulky subwoofer box. JL Audio's Stealthbox® subwoofer systems solve this problem, while delivering a level of sub-bass performance that is way ahead of the curve. And, as their name implies, they don't get in your way or call attention to themselves visually.

Our engineers begin the Stealthbox® design process by studying the acoustics of the target vehicle and evaluating potential Stealthbox® locations.

Extensive testing takes place with the goal of maximizing performance while minimizing loss of vehicle utility and comfort. Then, we choose from our vast arsenal of acclaimed subwoofers and our extensive bag of loading techniques, to produce the best possible subwoofer response for each and every Stealthbox® vehicle. Prototypes are evaluated and fine-tuned to further improve sound quality, output, cosmetics and fit. After a month or two (sometimes three), a Stealthbox® design is ready for production.

In addition to subwoofers, the Stealthbox® for Powersports line also includes vehicle-specific speaker systems. Like the Stealthbox® subwoofers, these are crafted from fiberglass and custom-engineered for a perfect fit in your UTV. These are loaded with our rugged marine-grade coaxial speakers for worry-free performance on the trail. RGB speaker lighting adds a custom touch.

With Stealthbox® for Powersports, great audio outdoors is simple to achieve.
