The MB Quart RW-108A is a compact, active powered subwoofer enclosure engineered to deliver powerful bass without consuming significant space, making it ideal for under-seat installation in cars, RVs, and ATVs. This subwoofer boasts a robust 600-watt total power output and a 4-ohm stable impedance, ensuring it can handle demanding audio needs. Constructed with a heavy-duty aluminum alloy heat-sink, the RW-108A is designed for efficient heat dissipation, allowing for sustained performance even during extended use at high volumes. Its wide frequency response, spanning from 58 to 20,000 Hz, captures a broad range of audio frequencies with precision, while the 91 dB signal-to-noise ratio guarantees crystal-clear sound with minimal distortion. For user customization, it features dual pair RCA inputs for easy connectivity and an adjustable bass boost that can provide up to a 12dB enhancement. The inclusion of a 25A fuse rating provides essential protection against electrical fluctuations and power surges, safeguarding the unit and your vehicle's electrical system. The compact and slim design facilitates installation in tight spaces, commonly found under car or truck seats, transforming your vehicle's audio experience with deeper, more impactful bass.
