Figure 1: Speaker Dimensions for Installation
1. Select a flat, sturdy mounting surface that can support the speaker's weight and withstand vibrations.
2. Using the provided template (if applicable) or the specified cut-out dimensions, carefully mark and cut the mounting hole.
3. Drill pilot holes for the mounting screws.
4. Position the speaker into the opening and secure it with the provided hardware. Do not overtighten screws.
Audio Wiring
The DS18 Hydro CF-10M speakers have an impedance of 4 Ohms. Ensure your amplifier is stable at this impedance. Connect the speaker wires to the appropriate positive (+) and negative (-) terminals on your amplifier.

Figure 2: Speaker Wiring Terminals
1. Identify the positive (+) and negative (-) terminals on the speaker and your amplifier.
2. Connect the positive speaker wire from the amplifier to the positive terminal on the speaker.
3. Connect the negative speaker wire from the amplifier to the negative terminal on the speaker.
4. Ensure all connections are secure and free from corrosion, especially in marine environments.
RGB Lighting Connection
The integrated RGB lights require a separate connection. These speakers are compatible with the DS18 LED-BTC controller (sold separately) for full color control via an app.

Operation
Audio Playback
Once properly installed and wired, your DS18 Hydro CF-10M speakers will reproduce audio from your connected source. Adjust volume and audio settings through your head unit or amplifier.
RGB Light Control
The RGB lighting can be controlled via an app when connected to a compatible DS18 LED-BTC controller. Refer to the controller's manual for specific instructions on changing colors, patterns, and brightness.
Maintenance
To ensure the longevity and performance of your DS18 Hydro CF-10M speakers, follow these maintenance guidelines:
- Cleaning: Regularly clean the speaker grilles and cones with a soft, damp cloth. Avoid harsh chemicals or abrasive cleaners that could damage the finish or waterproof seals.
- Water Resistance: While the speakers are IP65 rated, avoid direct high-pressure water sprays. After exposure to saltwater, rinse with fresh water to prevent salt buildup and corrosion.
- UV Stability: The materials are 100% UV stable, but prolonged exposure to extreme sunlight can still cause minor fading over many years.
- Inspections: Periodically check all wiring connections for tightness and signs of corrosion or wear.
Troubleshooting
If you encounter issues with your speakers, refer to the following common problems and solutions:
- No Sound:
- Check all audio wiring connections at both the speaker and amplifier.
- Verify the amplifier is powered on and functioning correctly.
- Ensure the audio source is playing and volume is turned up.
- Distorted Sound:
- Reduce the volume level to check if distortion is due to overdriving the speakers or amplifier.
- Inspect speaker cones for any physical damage.
- Check for loose wiring connections.
- RGB Lights Not Working:
- Ensure the DS18 LED-BTC controller is properly connected and powered.
- Verify the app control is functioning and settings are correct.
- Check RGB wiring for secure connections.
