Frequently Asked Questions - MS-OS420 Fusion

How do I troubleshoot if there is no sound from the speakers?

Check all connections from the source unit/amplifier to the speaker terminals. Ensure they are connected correctly and securely.

What should I do if the system lacks bass?

Verify the connections from the source unit/amplifier to the speaker. Ensure the positive wire is connected to the positive terminal of the speaker.

Why do I hear distorted sound?

Check all wiring for loose or damaged connections. Also verify that the amplifier output is not clipping or overdriving the speakers.

The high frequencies seem weak. What could be the issue?

Check the polarity of the connections. Also adjust the bass/treble control settings on the source unit to ensure treble is not reduced.

Can I install these speakers indoors?

Yes, they are designed for marine/outdoor use but can be installed indoors. Optimize placement for best sound stage.

What is the recommended mounting position for best sound?

Place speakers at ear level if possible to preserve high frequencies. Avoid placing them low as high frequencies are directional. Position them to create a balanced stereo image.

Are these speakers waterproof?

They are marine-grade and optimized for outdoor use, but not fully submersible. They can withstand splashes and typical marine environments.

How do I register my product?

What tools are needed for installation?

You will need a drill, screws (provided), and a screwdriver. Mounting brackets and knobs are included.

Can I use these speakers with a high-power amplifier?

The maximum power handling is 100W per speaker. Use an amplifier that delivers clean power within that range to avoid damage.

INSTALLATION TIPS

Any speaker will perform to its best capabilities, when correctly placed in the listening area. FUSION Engineers recognise that unlike a home or motor vehicles installation, there are an extremely wide range of marine environments where speakers may be placed. FUSION Marine Speakers are optimised to perform in the widest possible range of mounting locations, but a little thought and care with placement will always be rewarded with better sound.

• High frequencies are directional. Placing the speakers low down in the boar will lose some of this information.
• Speakers should be placed to simulate “sound stage”, by being placed where you are able to hear both speakers in a stereo situation.

TROUBLESHOOTING

Before you contact your FUSION dealer or service centre, FUSION requires that you do some simple trouble shooting to help diagnose the problem.

Problem Solution
