MB Quart Q Series 1500W Monoblock Subwoofer Class D Amplifier with Bass Remote

The MB Quart Q Series 1500W Monoblock Full Range Class D Amplifier was built for the moments music matters most, the long drives, the quiet mornings, the songs that need room to breathe. This mono-block subwoofer amplifier brings warmth and depth to your car audio setup, with a through-glass top design and soft red LED accent lighting that feels as intentional as the sound itself.

At its heart is the Q-Stasis pre-amplifier stage, engineered to quiet incoming noise from source units so what comes through is clean, honest sound. Nickel-plated RCA inputs offer a secure, corrosion-resistant connection, while mono operation is optimized to power a single subwoofer or subwoofer system, working seamlessly alongside the QA1-900.6DSP for a setup that feels whole rather than pieced together.

Care shows up in the details. An extruded aluminum heat sink, machined to its final shape, helps this Class D monoblock amplifier run efficiently at lower impedance for longer stretches, supported by a MOSFET power supply that produces strong output without overworking your vehicle's electrical system. Heavy-duty, nickel-plated output connections resist corrosion, so the bond between amplifier and wiring stays steady over time. Three-stage LED protection circuitry quietly watches over thermal, overload, DC, and speaker short conditions, a small reassurance built into every drive.

A wired bass remote is included, so you can adjust gain levels from wherever it's mounted in your vehicle, easily and on your terms.

This is a subwoofer amplifier made with the same care as everything else in the Q Series lineup: efficient, dependable, and built to let your bass feel as good as it sounds. Made to last. Designed to love.
