BMW’s breakthrough Sports Activity Vehicle offers a beautiful balance of driving dynamics, luxury and utility. The only thing missing is an equivalent audio experience anchored by a true subwoofer system.

The Stealthbox® solution for the X5 tucks away neatly behind the rear cargo panel and houses a robust 10-inch subwoofer driver. While it mounts in the same location as the optional BMW subwoofer, the difference in performance is simply staggering.

THE HARD DATA:

Contains one 10W1v2-4 subwoofer in a sealed enclosure. 300 Watt power handling. Wired for 4 ohm mono. Installs in the rear cargo area behind factory panel. Replaces OEM “subwoofer” system, if vehicle is so equipped.
