KX Amplifiers combine a sleek look and potent features with up to 2,400 watts of Earth-shattering power.
Next Level Knob
A revolutionary wireless remote that goes way beyond a simple bass knob. Control as many as four amplifiers simultaneously, including mono KX amps and the bass channel of the KXA800.5. Monitor and control vital functions of the amp including clipping, gain, phase, bass boost and more.
In any audio system, the goal is to reach maximum input and output levels without distortion or clipping. Sometimes, without expensive or complicated equipment like an oscilloscope, this can be a daunting task for a would-be-audiophile install. Thankfully, the engineers at KICKER have taken the guesswork, and hassle, out of matching the output voltage of your source unit to the amplifier. To begin, you’ll need to download the KICKER test tones here: Test Tones
