- Attach Speakers: Slide the speakers onto the installed brackets. Adjust the speaker angle and tighten the knobs to secure them in place.

4.2 Wiring the Speakers
The Herdio speaker system consists of one active speaker and one passive speaker. The active speaker contains the amplifier and Bluetooth module, while the passive speaker connects to the active one via the provided speaker cable.
- Connect Passive to Active: Locate the red (+) and black (-) terminals on the back of both speakers. Connect the red wire of the speaker cable to the red terminal on both speakers, and the black wire to the black terminal on both speakers. Ensure a secure connection by turning the terminal clockwise to tighten.
- Power Connection: Plug the 12V power adapter into the DC 12V input port on the active speaker. Then, plug the power adapter into a suitable electrical outlet.

5. Operation
