Fusion 0100228445 4 Channel Marine Amplifier

More Zones. More Power. Less Battery Drain.

The Fusion 4-Channel Marine Zone Amplifier is built for boaters who want to expand their audio system beyond the helm — adding high-quality sound to the cockpit, bow, cabin, or any combination of zones without sacrificing clarity or battery life. At 150W RMS per channel (4 ohm), this amplifier delivers serious output with the efficiency Fusion is known for.

Designed from the ground up for the marine environment, the Fusion zone amplifier features a conformal coated circuit board, ignition protection, and full resistance to salt fog, UV, temperature extremes, and vibration — so it performs reliably whether it’s mounted in an engine compartment, under a seat, or in a dedicated electronics bay.

Key Features

• 150W RMS Per Channel (4 Ohm) — High-output power across all four channels for clear, full-volume sound in multiple zones
• 4-Channel Zone Amplifier — Expand your audio system to additional speaker zones throughout the vessel
• 2 Ohm Stable — Connect up to two speakers per channel for increased setup flexibility and more coverage per zone
• Easy Tune — Automatically optimizes audio settings for best sound quality without manual EQ adjustments (requires Fusion-Link™ app on a compatible smartphone)
• Efficient Power Design — High output with minimal battery drain — critical for extended time on the water
• Conformal Coated PCB — Circuit board sealed against humidity and corrosion for long-term marine reliability
• True Marine Protection — Rated against salt fog, UV, temperature extremes, and vibration
• Ignition Protected — Meets ABYC and ISO standards for safe installation near fuel systems
• LED Fault Indicators — Quickly identify electrical issues at a glance without pulling the unit
• 12V Compatible — Works with standard 12-volt marine electrical systems
• Complete Hardware Included — Mounting brackets, connectors, and hardware included for a clean installation

⚓ Parts Desk Insight

• Zone amplifier — not a standalone head unit replacement: This amplifier requires a source unit (head unit or receiver) with RCA preamp outputs. Customers should confirm their existing receiver has RCA outputs before purchasing.
• Easy Tune requires the Fusion-Link™ app: The automatic audio optimization feature is set up via the Fusion-Link app on a compatible smartphone. Without the app, the amplifier still functions normally — Easy Tune just won’t be configured.
• 2 ohm stability doubles speaker options per channel: Running two speakers per channel at 2 ohm is a practical way to cover more zones without adding more amplifier channels. Customers should confirm their speaker impedance before wiring in parallel.
• Ignition protection is a code requirement in many installations: If the amplifier is being mounted in or near the engine compartment, ignition protection is required by ABYC standards. This unit meets that requirement — worth confirming with customers who are comparing against non-marine amplifiers.
