KICKER ZX-Series Amplifiers provide the utmost reliability from the biggest name in trouble-free amplification and loud, clear sound. Two-channel, four-channel, a five-channel hybrid, and absurd single-channel subwoofer amps round out a hard-working, noise-free lineup with heat sinks that can be personalized with edgy vinyl skins. An often overlooked benefit is that each individual KICKER Amplifier’s actual power always exceeds its rated power, as documented inside the carton. All KICKER Amplifier models use balanced differential inputs, making them compatible with any factory radio and eliminating unwanted noise within the audio system. A muting circuit cancels out additional noise that may surge down the line, so listeners enjoy the cleanest, clearest sound possible. Additionally, a choice of three automatic turn-on modes (remote, DC offset, signal sense) provide ultimate flexibility. Gain and crossover frequencies are top-mounted for easy access to fine tuning.
