Understanding Your 2015 Subaru WRX Radio Wiring Diagram
The 2015 Subaru WRX radio wiring diagram is essentially a blueprint for your car's audio system. It illustrates the electrical connections between the factory head unit (your car's radio), speakers, amplifier (if equipped), and other related components like power sources and ground connections.

These diagrams are typically presented in a clear, schematic format. They use specific symbols to represent different electrical components and lines to show the pathways of the electrical current. For instance, you'll see different colored wires on the diagram corresponding to specific functions. Understanding these color codes is paramount. Here's a general idea of what you might find, though always refer to your specific WRX's diagram for accuracy:
- Power: Usually indicated by a constant 12V supply from the battery and an ignition-switched 12V supply that turns on with the car.
- Ground: The connection to the car's chassis for a safe return path for the electrical current.
- Speaker Outputs: Separate wires for each speaker (front left, front right, rear left, rear right) carrying the audio signal.
- Antenna: The connection for your radio antenna.
- Illumination: A wire that dims the radio display when your headlights are turned on.
- Accessory (ACC): A wire that receives power only when the ignition is in the accessory position.
Here's a simplified representation of what a basic connection might look like:
| Diagram Wire Color (Example) | Function |
|---|---|
| Yellow | Constant 12V Battery Power |
| Red | Ignition/Switched 12V Power |
| Black | Ground |
| Blue | Power Antenna / Amp Turn-On |
| Orange | Illumination/Dimmer |
