To effectively use the 2011 Subaru Legacy Radio Wiring Diagram, you'll typically find the following types of connections represented:
-
Power Connections:
These provide electricity to the radio.
- Constant 12V Power (Battery): Always live, used to maintain radio presets and memory.
- Accessory 12V Power (Ignition): Powers the radio when the ignition is on.
- Ground Connection: This is a vital connection to the vehicle's chassis to complete the electrical circuit.
- Speaker Connections: Wires leading to each individual speaker. These are usually separated for the left and right front and rear speakers.
- Illumination Wire: Connects to the vehicle's dashboard lights, allowing the radio display to dim with headlights.
- Antenna Control/Power Antenna: If your car has a power antenna, this wire controls its operation.
Here’s a simplified table showing common wire color functions you might encounter, though always verify with your specific diagram:
| Wire Color | Function |
|---|---|
| Yellow | Constant 12V (Battery) |
| Red | Accessory 12V (Ignition) |
| Black | Ground |
| Blue | Antenna/Power Antenna |
| White | Left Front Speaker (+) |
| White/Black | Left Front Speaker (-) |
