- Ground Wire: This is vital for completing the circuit and ensuring proper operation. It's usually a black wire.
- Speaker Wires: These carry the audio signal to each speaker. Each speaker will have a positive and negative wire.
- Antenna Turn-On/Remote Turn-On: This wire signals an amplifier to turn on when the head unit is powered.
