Audio System SW11 ACTIVE

The Audio System SW11 ACTIVE is the ideal solution for anyone who wants to enjoy powerful bass without sacrificing valuable storage space in their vehicle. Thanks to its intelligent design, the active subwoofer is mounted in the spare tire well to save space and integrates almost invisibly into the vehicle. The sturdy die-cast aluminum housing minimizes vibrations and resonance, ensuring precise, clean bass even at higher volume levels.

The built-in mono power amplifier ensures easy installation, while RCA and high-level inputs—including an automatic power-on function—enable seamless connection to factory or aftermarket systems. With an adjustable low-pass filter, bass boost, gain, and phase reversal, the sound can be optimally tailored to the vehicle and your personal music preferences. The included wired remote control allows for convenient bass control right from the driver’s seat.
