Marine amplifier MS-AP61800

The Fusion MS-AP61800 marine amplifier is designed to be compatible only with Fusion marine audio systems equipped with DSP (Digital Signal Processing) technology. It is not recommended for use with third-party marine audio systems, as this could damage the speakers due to the amplifier's output power.

You have two main options for mounting the Fusion MS-AP61800 marine amplifier:

Mounting with the included bracket: This method uses the supplied bracket and pan-head screws to quickly attach and detach the amplifier. It requires clear space above the mounting location for connecting to the bracket and installing the locking wedge.Direct surface mounting: This option uses the supplied countersunk screws to mount the amplifier directly onto the surface. It does not allow for quick detachment but requires less clear space above the mounting location, which may be ideal for confined spaces.

For the electrical installation of the amplifier, you will need the following cables and wires:

For power and ground: A tinned marine-grade copper wire of 4 AWG (21 to 25 mm²) is recommended for most installations. For power cable runs longer than 5 meters (16 feet), a larger diameter wire (lower gauge number) may be required to minimize voltage drop.

For speakers: A tinned marine-grade copper wire of 12 AWG (3 to 4 mm²). Larger diameter wires may be needed for longer speaker wire runs.

For remote-on signal: A tinned marine-grade copper wire of 20 AWG (0.5 to 0.75 mm²).

RCA cable: A single-channel RCA cable for signal inputs.

When selecting the mounting location, consider the following points:

The amplifier must be mounted in a location that does not interfere with the fuel tank or electrical wiring. It must be installed in a dry place, protected from water, fuel, or fuel vapors. Choose a well-ventilated location not exposed to extreme temperatures. If installation is in an enclosed space, adding a cooling fan with appropriate ducts is recommended. Ensure cables can be connected easily. Never mount the amplifier upside down under a horizontal mounting surface. Keep the amplifier at a specified distance (as indicated in the product specifications) from a magnetic compass to avoid interference. Avoid mounting it near other critical navigation equipment, antennas, or radio communication devices.

Yes, after physically installing the amplifier, you must configure your stereo connected via the Fusion-Link™ app. This step is essential to select and activate the correct DSP profile, thereby optimizing the audio performance of your system.

The Fusion MS-AP61800 marine amplifier is covered by a limited 3-year (36-month) warranty for marine consumers. This warranty covers material and manufacturing defects.

The limited warranty may be voided if any of the following conditions apply:

Abnormal use, abnormal conditions, improper storage, unauthorized modifications or connections, unauthorized repairs (including the use of unauthorized spare parts). Misuse, negligence, abuse, accident, alteration, incorrect installation, natural disasters, spillage of food or liquids, improper adjustment of customer controls, or other acts beyond reasonable control of Fusion. Deficiencies in consumable parts (such as fuses) or breakage/damage to antennas, unless directly caused by material or manufacturing defects, or normal product wear. Fusion was not notified of the defect or malfunction during the applicable warranty period. The product’s serial number or accessory date code has been removed, degraded, or altered. The product was used with or connected to an accessory not provided by Fusion or unsuitable for use with a Fusion product, or used in a manner other than intended. Damage caused by water or extreme temperatures is not covered by the warranty.

If you encounter difficulties during installation, it is recommended to consult the product support at support.garmin.com. It is also strongly advised to have your audio system installed by a professional installer to ensure optimal performance.

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

The net weight of the Fusion MS-AP61800 marine amplifier is 3.97 kg.

Do not print a mounting template yourself. Use the template provided in the product box. If you must print the template, strictly follow the instructions to ensure 100% scale, including using the correct paper size and printer settings, and verify the dimension with a ruler after printing. Garmin is not liable for damage or expenses resulting from incorrect cutting of the mounting surface due to failure to follow these instructions.

Before starting installation, disconnect the boat's audio system power supply. To prevent personal injury, always wear safety glasses, hearing protection, and a dust mask when drilling, cutting, or sanding. Also refer to the "Important Safety and Product Information" guide provided in the product box for specific warnings.

You must connect the "REM" terminal of the amplifier's power block to the "AMPLIFIER ON" wire of your connected stereo. This method is recommended to prevent damage to your speakers when turning the stereo on or off. Alternatively, you can connect it to a constant 12 V DC power source via a switch, but connecting to the stereo is preferable.

This device is designed to be installed only in a dry location. Installing it where it could come into contact with more than occasional water droplets or be submerged may result in damage. Water damage is not covered by the warranty.

The Fusion Marine MS-AP61800 amplifier is a 6-channel amplifier, delivering 150 watts RMS per channel.

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

No, it is strongly advised against using this amplifier with third-party marine audio systems or speakers from another brand. The MS-AP61800 amplifier is compatible only with Fusion DSP-compatible marine audio equipment and could damage third-party speakers due to its output power.

The device must be mounted in a well-ventilated area that is not exposed to extreme temperatures or conditions. After prolonged use and in high ambient temperatures, the device housing can reach dangerous touch temperatures. It must therefore be installed in a location where it will not be touched during operation. Damage caused by extreme temperatures is not covered by the warranty.

You must not mount this device upside down on the underside of a horizontal mounting surface. Mounting the device in an inverted orientation reduces the effectiveness of heat dissipation and may cause shutdown due to thermal protection.

No, this Fusion MS-AP61800 marine amplifier is not compatible with marine audio systems from other brands.

It is exclusively designed to be used with compatible Fusion DSP marine audio equipment. Using this amplifier with third-party speakers could cause damage due to its output power.
