Kicker 51LX30001 3000w Mono Car Amplifier w/Smart Bass Class D Sub Amp LX3000.1

The LX3000.1 is a monoblock Class-D amplifier built to run the subwoofer stage in a car, truck, or SUV. It makes 3000W RMS at 1-Ohm, 2000W at 2-Ohm, and 1100W at 4-Ohm, so one chassis covers everything from a single high-power sub to a multi-woofer build. Class-D output keeps current draw and operating temperature down, which matters when the system plays loud for hours on a charging system that also has to run the rest of the vehicle.

Setup is built for repeatable results. Gain-match LEDs show you when input level is set correctly instead of leaving it to guesswork. FIT+ technology accepts low-level signals from 125mV to 5V and speaker-level signals up to 40V, so the amp connects to an aftermarket head unit or a factory radio without a separate line-out converter, and differential inputs reject alternator whine and other noise picked up along the run. A 24dB/octave Linkwitz-Riley low-pass sweeps 40 to 160Hz, and a matching subsonic filter sweeps 10 to 80Hz to keep the woofer inside its excursion limits in a ported box. KickEQ+ parametric bass boost adds 0 to 6dB with a variable 20-80Hz center and adjustable bandwidth for tuning around cabin acoustics.

The included LXRC dash remote puts bass level at your fingertips and adds SHOCwave2.0, KICKER's second-generation sub-harmonic restoration algorithm that rebuilds low bass lost in compressed source material. The remote also shows battery voltage in a fuel-gauge readout, controls RGB brightness, and flags output clipping before it costs you a woofer. Selectable turn-on modes plus thermal, circuit, and voltage protection cover the install, while a reversible center panel and 11 RGB accent colors let the amp match a show build or stay understated in a daily setup.
