Marine amplifier Fusion MS-AP41200

The Fusion Marine MS-AP41200 amplifier is a 4-channel model. It is designed for marine audio systems requiring power and sound fidelity.

This amplifier delivers 150 watts RMS per channel at 4 ohms. It can also deliver 290 watts RMS per channel at 2 ohms.

Yes, the MS-AP41200 amplifier is a marine amplifier, meaning it is designed to withstand the demanding conditions of a marine environment.

This amplifier is compatible only with Fusion marine audio equipment featuring DSP (Digital Signal Processing) technology. It is not compatible with third-party marine audio systems.

It is strongly advised against using this amplifier with third-party marine speakers. The amplifier is only compatible with Fusion DSP-compatible marine audio equipment and may damage third-party speakers due to its output power.

Before starting installation, it is crucial to disconnect the boat's audio system power supply. It is also strongly recommended to have your audio system installed by a professional installer to ensure optimal performance. The amplifier must be installed in accordance with the provided instructions.

For installation, you will need the following tools and materials:

A 40 A inline fuse or circuit breaker. A drill and a 3 mm (1/8 in) bit or suitable for your hardware and mounting surface. Screwdrivers: flat 5 mm (7/32 in), flat 4 mm (5/32 in), Phillips #2 and Phillips #0. Wire cutters and wire strippers. Marine-grade tinned copper wire: 4 AWG (21-25 mm²) for power and ground, 12 AWG (3-4 mm²) for speakers, 20 AWG (0.5-0.75 mm²) for remote start signal, and a single-channel RCA cable. Cable ties (optional).

For most installations, it is recommended to use a fully tinned marine-grade 4 AWG (21 to 25 mm²) copper wire to connect the amplifier to the power supply and ground. For power cable lengths exceeding 5 m (16 ft), use a larger diameter wire (lower AWG number) to minimize power loss.

Use fully tinned marine-grade 12 AWG (3 to 4 mm²) copper wire for speakers. For long speaker wire runs, a larger-diameter wire (smaller AWG number) may be required.

The amplifier must be mounted in a dry, well-ventilated location, protected from extreme temperatures, water, fuel, or fuel vapors. It must not obstruct the fuel tank or electrical wiring. Avoid mounting it upside down under a horizontal mounting surface, as this reduces heat dissipation efficiency. To prevent interference with a magnetic compass, mount the amplifier at the specified distance from it, as indicated in the product specifications.

You can mount the amplifier in two ways:

With the included bracket: This allows for quick attachment and removal of the amplifier. This method requires 100 mm (4 in) of clearance above the mounting location.Directly on the surface: Using the included countersunk screws, the amplifier is mounted more permanently. This option requires less clearance above (25 mm / 1 in) and may be better suited to tight spaces.In both cases, sufficient clearance for cable bend radius and tool access is required.

To avoid interference or unwanted noise in the audio signal, do not route RCA cables alongside power cables. Also protect all cables from sharp objects and use rubber grommets when routing them through metal panels.

Yes, after installing the amplifier, you must configure your stereo system connected to it using the Fusion-Link™ app to select and activate the correct DSP profile.

You must connect the REM terminal of the amplifier block to the AMPLIFIER ON wire of your connected stereo system, or to a constant 12 V DC power source via a switch. It is recommended to connect to the AMPLIFIER ON wire of the stereo system to avoid damaging your speakers when the stereo system powers on or off.

Yes, after installing an audio system, it is recommended to run the speakers and subwoofers connected at low to moderate volumes during their first hours of use. This helps improve overall sound by gradually breaking in the moving components of new speakers and subwoofers, such as the cone, spider, and surround.

The unit must be installed in a well-ventilated area and must not be mounted upside down under a horizontal surface, as this reduces the effectiveness of heat dissipation and may cause shutdown due to thermal protection. If the amplifier is installed in an enclosed space, it is advisable to install a cooling fan with appropriate ducts to promote air circulation.
