KICKER® ZXM-Series Amplifiers for recreational watercraft provide dependability and flexibility to any high-performance audio system on the water. Special weather-resistant features give ZXM Amplifiers enhanced ability to withstand the marine environment while powering up an incredible sounding system.

Each model is sprayed with a moisture-deterring, protective conformal coating on the inner circuit board, and fuses and power connections also meet marine industry standards* for protection against the elements.

The ZXM350.4 Four-Channel (90w x 4) amp features an additional, often overlooked benefit: Each individual KICKER Amplifier’s actual power always exceeds its rated power, as documented inside the carton.

KICKER Amplifiers make powering an audio system simple and steady. All 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.

For ideal system setup, a choice of three automatic turn-on modes (remote, DC offset, signal sense) makes for ultimate flexibility. Gain and crossover frequencies are top-mounted for easy access to fine tuning.

KICKER is a member of the American Boat & Yacht Council (ABYC), a leader in education for the marine industry, and the National Marine Manufacturers Association (NMMA), which supports the U.S. recreational boating industry.
