Kicker KMA6004 600-Watt 4-Channel Marine Power Amplifier

Power your boat's entire audio setup with clear, high-output efficiency using the Kicker KMA600.4 4-Channel Marine Amplifier. Engineered specifically to handle the harsh, open-water environment, this Weather-Resistant Class-D amplifier delivers up to 600 watts of peak power to drive up to eight marine speakers, or a combination of speakers and a subwoofer. Featuring Real Marine™ construction, marine-grade conformal-coated circuit boards, and flexible crossover adjustments, the KMA600.4 provides high-volume, distortion-free sound that easily cuts through wind and engine noise.

Key Features & Benefits:

• High-Efficiency Class-D Power: Produces massive output with minimal current draw on your boat’s battery system, keeping your electrical system reliable during long days on the water.

• Flexible 4-Channel Configuration: Capable of powering four full-range speakers, eight speakers wired in parallel, or bridged to deliver 2x 300W RMS to power a pair of subwoofers or tower speakers.

• Real Marine™ Weatherproof Construction: Features conformal-coated circuit boards, stainless-steel hardware, and ABYC/NMMA-compliant power terminals designed to prevent corrosion from humidity and salt spray.

• Variable Crossovers & KickEQ™ Bass Boost: Built-in 12dB/octave high-pass and low-pass filters, along with variable KickEQ™ bass boost (0–6dB @ 40Hz), allow for precise frequency tuning.

• Fail-Safe Integration Technology (FIT2™): Ensures exceptional noise rejection and compatibility with both factory head units and aftermarket marine media centers.

• Sleek Stainless-Steel Heat Sink: High-density aluminum casing keeps internal components cool under high-output conditions while providing a stylish look on deck or in storage compartments.

Ideal Applications:

• Full Boat Speaker Powering: Ideal primary power amplifier for driving multiple deck, cabin, or bow speakers on center consoles, pontoon boats, and bowriders.

• 3-Channel Hybrid Systems: Perfect for running a pair of coaxials on channels 1 & 2 while bridging channels 3 & 4 to drive a 4-ohm marine subwoofer.

Tech Tip: When installing in a marine battery setup, use a marine-grade OFC (Oxygen-Free Copper) 4-gauge amplifier wiring kit with an ABYC-compliant fuse placed within 18 inches of the battery terminal.
