4.3 Wiring and Connection
Follow these steps to connect your speakers to the Bluetooth amplifier:
- Connect the speaker cables to the speakers: Ensure the red wire connects to the positive (+) terminal and the black wire to the negative (-) terminal on each speaker.
- Connect the speaker cables to the Bluetooth amplifier: The amplifier has clearly marked terminals for SPK L+ (Left Speaker Positive), SPK L- (Left Speaker Negative), SPK R+ (Right Speaker Positive), and SPK R- (Right Speaker Negative). Use a screwdriver to secure the wires.
- Connect the power supply: Plug the 24V/3A power supply into the 'Power Jack' input on the Bluetooth amplifier, then plug the power supply into an AC outlet.

7. Troubleshooting
If you encounter issues with your Herdio HCS-818BT speakers, refer to the following common troubleshooting steps:
