ESX Q168A

The ESX QUANTUM Q168A active subwoofer system offers a space-saving way to enhance your vehicle’s factory sound system with powerful bass reproduction. Thanks to its exceptionally slim design, the subwoofer is ideal for installation under or behind the vehicle seats, as well as in small storage compartments.

Inside is a 15 x 20 cm (6 x 8-inch) specialty subwoofer powered by a built-in Class A/B amplifier with 100 watts RMS. The rugged cast aluminum enclosure aids in heat dissipation and protects the amplifier circuitry from overheating.

For personalized sound tuning, the system features an adjustable low-pass filter, a bass boost, and a switchable phase control. The included bass level remote control allows you to conveniently adjust the bass volume from the driver's seat.

Thanks to its RCA and high-level inputs, as well as its automatic power-on function, the ESX Q168A can be paired with both aftermarket and many factory-installed car stereos. It offers a compact solution for bass enhancement, particularly for small cars, sports coupes, and convertibles.
