The Kicker LX1650.1 mono amplifier is engineered in the USA to serve car audio systems requiring premium amplification, high power, and flexible system design. It's described as a perfect marriage of SQL design and high-powered output, offering DSP-powered features and remote control capabilities. This Class-D amplifier is built for performance and durability, featuring KICKER’s FIT+™ (Fail-safe Integration Technology-PLUS) which accepts low- and high-level signals up to 40V. The amplifier also includes a choice of turn-on modes and comprehensive protections against thermal, circuit, and voltage stability issues for reliable operation. The LX1650.1 comes with the LXRC (LX Remote Control) dash remote, which provides fingertip control of bass level. This remote also features SHOCwave2.0™, KICKER’s digital bass restoration algorithm, a battery voltage meter, RGB LED brightness control, and an output clipping indicator. Gain-Match LEDs are included to help achieve the optimal gain setting. The amplifier's aesthetic can be customized with a reversible center panel and 11 RGB LED accent colors. Key specifications include 1650W RMS power at 1 ohm, 1000W RMS at 2 ohms, and 550W RMS at 4 ohms. It has a frequency response of 10–160 Hz (+0/–1 dB), a signal-to-noise ratio of >95 dB (rated power), and supports low-level input sensitivity from 125 mV–5 V and high-level input sensitivity from 1 V–40 V. The variable electronic crossover operates at 40–160 Hz (24 dB/octave), and the subsonic filter ranges from 10–80 Hz (24 dB/octave). The KickEQ+™ parametric bass boost offers 0–6 dB adjustment with a variable center frequency from 20–80 Hz and variable bandwidth from 1–5. The amplifier includes a 19.75-foot (6m) RJ45 cable for the remote.
