SHIFT INTO BIG POWER
KX Mono Subwoofer Amps produce the most power from any single KICKER amplifier, 2,400 rated watts surging to raucous CompR™ or CompRT™ Subwoofers. Without question, we know bass and bass power, and KICKER actual power always exceeds rated power.
BOOST CONVERTER EFFICIENCY
KX monoblock amps use a Class-D, boost-converter power supply for the highest sound quality and efficiency. Boost-converter technology allows KX.1 amps to achieve a typical efficiency near 80 percent, significantly beyond standard amp power supplies.
KX Amplifiers set the curve for smaller chassis footprints, with the largest model (2400.1) measuring at only 15-1/2 inches long. KICKER amps feature an optimized circuit layout for the most efficient use of components, the smallest footprint and clearest sound quality.
DEPEND ON THIS SUB AMP
Class-D power, boost-converter power supplies, and the adaptability to use fewer internal parts allow for a smaller bass-amp size, the coolest operation, optimum reliability and overall excellent performance.
A remote level control, available with all KX.1 amps, provides bass volume from the dash. Users can take advantage of built-in crossovers and adjustable KickEQ™ processing for dialing in perfect sound, and a variable high-pass subsonic filter provides subwoofer protection from potentially damaging lowest frequencies.
