MS10LB + KTA-30MW Marine Audio Package

Build fuller low-frequency sound into a boat or open-cab vehicle with a 10-inch free-air subwoofer and a compact mono amplifier in one package. The subwoofer’s polypropylene cone, rubber surround, dual 4-ohm voice coil, and 90 dB sensitivity deliver bass down to 30 Hz without requiring a dedicated enclosure, when installed with at least 1.5 cubic feet of air space. A double-stacked 80 oz magnet supports the subwoofer’s 600W RMS rating, while its marine-grade construction, UV treatment, waterproof coating, and molded ABS basket suit saltwater and freshwater environments. The IP66-rated amplifier fits tight spaces and works with factory or aftermarket head units. Its Class D circuit provides 300W RMS and uses Dynamic Peak Power for brief output up to 600W. Selectable speaker or RCA inputs, variable gain, and a 50-400 Hz low-pass filter help integrate the system with a compatible setup.
