ESX Q300Av2

The ESX QUANTUM Q300A V2 is a compact active subwoofer designed specifically for space-saving installation in the spare tire well. Thanks to its flat, round design, the system can be discreetly integrated into the trunk without unnecessarily taking up valuable storage space.

Inside, a powerful 15 × 23 cm (6 × 9-inch) specialty subwoofer is powered by a built-in Class D digital amplifier delivering 150 watts RMS. The combination of efficient amplifier technology and a compact enclosure design enables powerful bass reproduction, specifically designed to enhance existing car audio systems.

Thanks to its built-in high-level inputs with automatic power-on function, the Q300A V2 is also suitable for retrofitting factory-installed sound systems. Alternatively, the signal can be transmitted via the existing RCA inputs. The included bass-level remote control allows you to conveniently adjust the bass volume from the driver’s seat.

The adjustable low-pass filter, bass boost, and phase switch allow for customization to match your existing speaker system. A fixed subsonic filter protects the subwoofer from unwanted low frequencies.
