Show original supplier description
The Kicker CXA1800.1 (46CXA18001) is a Class D mono amplifier engineered to power demanding subwoofer systems, delivering a substantial 1800 watts RMS at both 2-ohm and 1-ohm impedances, with a peak output of 3600 watts. It offers comprehensive low-end control with onboard 12dB crossovers adjustable from 50-200Hz, a KickEQ boost providing up to +12dB at a 40Hz center, and a fixed 24dB/octave subsonic filter at 25Hz to protect your woofers. Integration is made easy with Kicker's FIT+ circuitry, which accepts source signals from virtually any factory or aftermarket head unit, handling speaker-level inputs up to 40 volts without needing an additional interface module. For a clean user experience, the amplifier features a three-second delay on both power-up and shutdown to prevent audible pops through the speakers. The optional CXRC bass knob is compatible and sold separately, allowing for convenient remote bass level adjustment. The amplifier includes vertical mounting hardware, enabling an upright installation orientation to accommodate tight spaces, with its compact chassis measuring 13-5/8" long, 2-3/8" tall, and 7-3/16" wide.
