Fusion AM504 4 Channel Marine Amplifier

The AM Series marine amplifiers deliver superior audio amplification specifically engineered for marine conditions, elevating your listening experience on the water with exceptional sound quality. The Class-AB amplifier design ensures efficient performance with minimized distortion. It supports connecting up to two speakers per channel at 2 ohms or bridging two channels at 4 ohms to boost power output. Conformal coated PCBs offer enhanced protection against harsh marine conditions, while the heat sink improves heat dissipation, increasing component durability.

Features

CLASS-AB AMPLIFIER TECHNOLOGY
The Class-AB design provides high power output with reduced distortion to the connected speakers/subwoofers for an enhanced level of audio performance.

ENHANCED SYSTEM PERFORMANCE
The AM Series amplifiers feature built-in variable bass boost, a subsonic filter and variable low/high pass crossover filters for enhanced performance and system protection.

MARINE-READY DESIGN WITH CONFORMAL COATED PCBS
Helping to extend the life of your amplifiers, the AM Series amplifiers are designed with conformal coated PCBs to provide extra protection from the marine elements.

HEAT SINK TECHNOLOGY
The incorporated heat sink is designed to dissipate heat efficiently, providing more thermal stability and enhanced component reliability.

500-WATT 4-CHANNEL AMPLIFIER
The AM Series 500-watt 4-channel amplifier can power up to a maximum of four pairs of speakers or two pairs of speakers and one subwoofer.
