Decoding Your 1997 Subaru Legacy Stereo Wiring Diagram
A 1997 Subaru Legacy Stereo Wiring Diagram is essentially a map that illustrates the electrical connections within your car's audio system. It shows you the color-coding of each wire and its specific function, whether it's for power, ground, speaker output, or auxiliary signals.

- Ground Wire: This is essential for completing the electrical circuit and preventing static or humming. It's usually a black wire.
- Speaker Wires: Each speaker will have its own set of wires, usually two for each speaker (positive and negative). The diagram will show which wires correspond to which speaker location (e.g., front left, rear right).
- Illumination/Dimmer Wire: This wire connects to your car's lighting system, allowing the stereo's display to dim when your headlights are on.
- Antenna Turn-On Wire: This wire powers your power antenna or power antenna relay when the stereo is turned on.
