- Ground Wire: This is essential for completing the circuit and often a common source of installation problems if not properly connected.
- Speaker Wires: Each speaker will have its own set of wires, typically color-coded to indicate positive and negative terminals.
- Accessory/Illumination Wires: These can control features like dimming the display with your headlights or providing power to an antenna.
