Perfect look. Perfect fit. Perfect bass.

If you are like most people, you spend more time listening to music in your car than any other place. Too bad most car stereos have weak sound quality, especially in the bass department.

Adding a subwoofer is the single, most significant improvement you can make to a car 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 small front and rear speakers in your car from the burden of reproducing bass. This makes them sound better, cleaner and louder.

Conventional subwoofers in the car can take up a lot of room and get in the way of people and cargo. JL Audio’s Stealthbox® subwoofer systems elegantly 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.

The result is a product that exceeds the conventional limits of system design, delivering performance so good that Truckin’ magazine declared:

“You never would think that a single 10-inch woofer... in a box made to blend in with the interior, could produce as much bass as a system with several 12-inch subwoofers...”
