KX Amplifiers come loaded with FIT™ (Fail-Safe Integration Technology) advanced circuitry for superior power, clarity and dependability. FIT is also responsible for convenient, automatic turn-on modes (DC offset or 12V remote).



Full-range KX models utilize Class D-IC power, which provides superior efficiency, exceptional sonic performance and the compact size.



A remote level control, available with the KX800.5, 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.



Double-sided fiberglass circuit boards, Litz-wound transformers that minimize power loss and maximize transfer, TO218 output devices for high-current switching, buffered RCA outputs on bass amps, angled custom-tooled power connectors – the details make our KX Amplifiers the most reliable, high-performing audio equipment in the industry.
