Kicker 51LX12501 1250w Mono Car Amplifier w/Smart Bass Class D Sub Amp LX1250.1

The KICKER LX-Series is the company high-power premium amplifier line, designed in-house from the ground up around sound quality and real-world control. The LX1250.1 is a Class-D monoblock rated at 1,250W into 1 ohm, 750W into 2 ohms and 400W into 4 ohms, with 1,600W of dynamic power for the peaks that make bass hit rather than hum.

The LXRC dash remote is included, not an accessory purchase. It puts subwoofer level under your fingertips and carries SHOCwave2.0, the second-generation sub-harmonic octave creation algorithm that rebuilds the low bass content stripped out of compressed streaming files. The same remote shows battery voltage in a fuel-gauge readout, controls RGB brightness and flags output clipping before distortion reaches the subwoofer.

Filtering is thorough for a monoblock. The low-pass is a 24dB/octave Linkwitz-Riley variable from 40 to 160Hz, and the subsonic filter uses the same slope from 10 to 80Hz to keep wasted excursion out of ported enclosures. KickEQ+ parametric bass boost offers 0 to 6dB with a variable 20 to 80Hz center point and adjustable bandwidth, so you can lift one problem frequency instead of the whole low end.

FIT+ technology accepts low- and high-level signal up to 40V through differential inputs that reject factory harness noise, which removes the line output converter from most factory-radio installs. Gain-match LEDs confirm correct gain during setup. Class-D design keeps current draw and operating temperature down for long play times, and protection circuits cover thermal, electrical and voltage faults. The center panel is reversible with a choice of 11 RGB accent colors.
