About the Fusion MS-AP61800
Fusion Apollo system
Fusion Apollo system
The Fusion MS-AP61800 marine amplifier is part of Fusion's Apollo Marine Entertainment System — a complete high-fidelity audio chain, from source through power to speakers, with no weak links. Apollo Series receivers, amps, and speakers are all designed to work together — so, for instance, this Apollo Series amplifier doesn't need any complicated onboard controls because everything's done through Fusion's Easy Tune software.
Using the Fusion-Link™ app on your compatible smartphone, you select the Apollo Series amp, speakers, and subwoofers you're using, and the DSP receiver will produce a fine-tuned signal dialed-in for optimum amp gain, crossover, and tone control settings. You can even choose different sound profiles for enclosed cabins, a helm area, or the open deck. You'll get perfect sound every time everywhere.
Power for your Fusion Apollo system
The Fusion Apollo MS-AP61800 six-channel amplifier puts out 150 watts RMS per channel, providing the muscle your music deserves in every listening zone on your boat. A bridging adapter is included so you could use two of the amp's channels bridged together to run a subwoofer with up to 580 watts RMS while powering four other speakers with 150 watts each. Efficient Class-D amp design ensures maximum power output with minimum drain on the battery system.
Made for life afloat
The amplifier's power is ignition-protected with an intelligent electronic fuse to prevent damage in case of an electrical fault. The weather-resistant, IPX2-rated (splash-proof) chassis, powder-coated aluminum finish, and conformal-coated circuit boards help Fusion's True-Marine™ Design amplifier survive harsh marine environments.

Marine Amplifier: The Fusion MS-AP61800 Apollo Series six-channel marine amplifier is designed specifically to be used with select Fusion DSP-enabled marine receivers and speakers. The amplifier is effectively three full range 2-channel amps built into one chassis. Each pair of channels is independently bridgeable, so the amp can be wired as 6-channel, 5channel, 4-channel, or 3-channel. Each 2-channel section of the amp (inputs and outputs) is labeled as a zone; Zone 1, Zone 2, and Zone 3. The amp's conformal-coated PCB (printed circuit board) protects it against the harsh marine environment, while its powder-coated aluminum chassis has been tested against salt fog, temperature, vibration, and UV-light. The Fusion MS-AP61800 marine amplifier carries an IPX2 waterproof rating.
Note: The Fusion MS-AP61800 marine amplifier can only be used with select Fusion DSP-enabled marine stereos and Fusion marine speakers.
Compatibility: The Fusion MS-AP61800 marine amplifier is designed specifically for use with select Fusion DSP-enabled marine radios, such as the Apollo RA670, RA770, WB670, and MS-RA210, along Fusion marine speakers, found here.
Class-D Amplifier Technology: The MS-AP61800 features a high efficiency Class-D design with these output specifications (14.4 volt power supply, <1% THD+N):
- 4Ω: 150 watts RMS x 6
- 2Ω: 290 watts RMS x 6
- Bridged (4Ω): 580 watts RMS x 3
- Signal to Noise Ratio:
- @ Rated Power: 67.5dB (4Ω)
- @ 1 Watt: 56dB (4Ω)
Fusion DSP: Designed for use with select Fusion DSP-equipped marine headunits and speakers, the Fusion-Link app, available for iOS and Android devices, lets you quickly and easily optimize your Fusion sound system. Fusion DSP uses environmental and headunit information, along with customized Fusion speaker profiles to tune your system for premium audio reproduction.
Note: The Fusion MS-AP61800 marine amplifier has no manual setup controls.
Protection Circuitry: The amp is equipped with a built-in circuitry to keep it operating safely. The circuitry protects against overheating (thermal), reversed power polarity, over/under voltage, and short circuited output conditions.
- RCA Inputs: Three pair of stereo RCA inputs; Zone 1, Zone 2, and Zone 3.
- Speaker Outputs: Three terminal block connectors with set-screw terminals (2-channels each) will accept up to 10-gauge wire. Bridge adapters are provided that can snap over a speaker output connector ensuring the proper terminals are used for a bridge connection.
- Power/Ground/Remote Turn-on: A single terminal block with set-screw terminals can accept up to 1/0-gauge wire for power and ground (4-gauge is recommended for wire runs 20' or less). The remote turn-on set-screw terminal can accept up to 10-gauge wire.
- Fuse: 125A internal electronic breaker.
LED Indicator: A top-panel LED can light to indicate the following:
- Green: Unit is powered on and functioning nominally.
- Orange (Recoverable Fault): The LED will light Orange if it detects a "recoverable" fault, such as under- or over-voltage, power/ground wire gauge issue (too small), or the amp is over heating. The amp will automatically try to recover from this type of fault. If multiple attempts are unsuccessful, the amp will switch to a "critical fault" status (Red LED).
- Red (Critical Fault): The LED will light red if it goes into a "critical fault" mode. This can be caused by repeated over- or under-current operation faults, prolonged over-temperature, incorrect DSP equipment selection in the Fusion-Link app, high volume issue (distortion), speaker or speaker wire fault, internal power supply fault. The critical fault mode will require the amp to be powered off, the problem remedied, and powered back on again.
Mounting: The MS-AP61800 marine amplifier includes a mounting bracket designed to mount the amp vertically to a cabin wall or console. Once the mounting bracket is installed on the wall, the amp is slid downward onto the bracket snapping into place. A locking-wedge is attached to the top of the bracket, keeping the amp from being removed without first removing the locking-wedge.
