Unleash deep, powerful bass from a compact, space-saving design with the DS18 SQBASS68, a 6x8” amplified under-seat subwoofer engineered to deliver rich, dynamic low frequencies without sacrificing cabin space. Perfect for vehicles with limited room, this slim yet potent system combines DS18’s advanced subwoofer technology with an integrated digital amplifier to redefine what’s possible in compact bass performance.

Built to fit effortlessly under most car seats, rear cubbies, or storage compartments, the SQBASS68 delivers the power and depth of a full-size subwoofer in a discreet, low-profile housing. With 150W RMS (600W Peak) power handling and a frequency response of 42Hz–400Hz, it brings your music to life with thunderous lows and precise definition. Every beat, thump, and drop resonates with clarity and power — the DS18 way.

Equipped with a built-in Class D monoblock amplifier, the SQBASS68 ensures superior efficiency, clean signal processing, and minimal distortion even at high output levels. The remote bass control knob (with a 16ft cable) allows you to fine-tune your bass from 0–30dB, putting total control right at your fingertips. Its signal-sensing auto turn-on simplifies installation, automatically powering up when it detects audio input.

Crafted with premium components, including a polypropylene cone, rubber surround, and steel basket housed in a durable aluminum chassis, the SQBASS68 is built for lasting performance. Multiple protection circuits — including thermal, overload, DC output, and short-circuit protection — ensure your system performs safely and reliably for years to come.

Compact yet commanding, the DS18 SQBASS68 delivers deep, responsive bass that will transform your in-car listening experience. Feel the rhythm, embrace the clarity, and let the bass move you — all from under your seat.
