- Ground Wire: This is essential for completing the circuit and preventing electrical noise. It connects to the car's chassis.
- Speaker Wires: These carry the audio signal to each individual speaker. You'll often see pairs of wires, usually with different colors or markings, to distinguish between the positive and negative terminals for each speaker.
- Antenna Wire: This connects to your car's antenna, allowing you to receive radio signals.
- Illumination Wire: This wire often connects to your car's dashboard lights, so your radio display dims when your headlights are on.
