6.3 Wiring Connections
The speakers require two sets of connections: one for audio and one for the LED lights.
- Audio Wiring: Connect the speaker's audio terminals to your amplifier or head unit. Ensure correct polarity (positive to positive, negative to negative) for optimal sound performance.
- LED Wiring: The blue LED lights require a separate 12V power connection. Connect the dedicated LED wires to a switched 12V power source. This allows the LED lights to be turned on and off independently of the audio.

7. Operation
7.1 Audio Playback
Once properly installed and wired, turn on your audio source (e.g., head unit, amplifier). Adjust the volume to your desired level. The speakers are designed to deliver clear audio with a 50-watt power handling capacity.
7.2 LED Lighting
If the LED wires are connected to a switched 12V power source, activate the switch to illuminate the blue LED lights. The LED lights operate independently of the audio playback.

8. Maintenance
To ensure the longevity and performance of your water-resistant speakers, follow these maintenance guidelines:
- Cleaning: Regularly wipe the speaker grilles and surfaces with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners, as these can damage the plastic and finish.
- Inspection: Periodically check all wiring connections for corrosion or looseness. Ensure mounting screws are secure.
- Water Exposure: While water-resistant, avoid prolonged direct exposure to high-pressure water jets. If used in saltwater environments, rinse with fresh water after use to prevent salt buildup.
- UV Protection: The speakers are UV protected, but prolonged exposure to intense sunlight can still affect their appearance over time.
