6. Wiring Instructions
Proper wiring is crucial for optimal sound quality and LED functionality. Refer to your audio source's manual for specific wiring diagrams if needed.
- Speaker Wiring: Connect the included speaker cables to the speaker terminals. Ensure correct polarity (positive to positive, negative to negative) from your amplifier or head unit. The included speaker wires are 9.8 feet long.
- LED Light Wiring: The blue LED lights require a separate power connection. Connect the LED light cables to a 12V DC power source. This allows independent control of the LED lighting.

Once installed and wired, operating your Herdio marine speakers is straightforward:
- Power On: Turn on your audio source (e.g., marine stereo, amplifier).
- Adjust Volume: Start with a low volume and gradually increase it to a comfortable listening level.
- LED Control: If wired to a separate switch, activate the blue LED lights as desired.
- Audio Source: Select your preferred audio input on your head unit or amplifier.
8. Maintenance
Regular maintenance ensures the longevity and performance of your speakers:
- Cleaning: Clean the speaker grilles and surfaces with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the material.
- Inspection: Periodically check mounting screws for tightness and wiring connections for corrosion or damage.
- Weather Protection: Although weather-resistant, covering the speakers when not in use, especially during prolonged storage or harsh weather, can extend their lifespan.
