Embarking on a car audio upgrade for your 2016 Subaru WRX can be an exciting project. To ensure a smooth and successful installation, understanding the 2016 Subaru WRX radio wiring diagram is absolutely essential. This diagram serves as the blueprint for connecting your new head unit or speakers, providing crucial information about each wire's function.
Understanding the 2016 Subaru WRX Radio Wiring Diagram
The 2016 Subaru WRX radio wiring diagram is a technical document that illustrates the electrical connections within your vehicle's audio system. It details the purpose of each wire emanating from the factory radio harness, including power, ground, speaker outputs, antenna signals, and control signals. For anyone looking to replace their stock stereo with an aftermarket one, or to add amplifiers and subwoofers, this diagram is invaluable.
Without a proper understanding of the 2016 Subaru WRX radio wiring diagram, attempting an audio installation can lead to blown fuses, damaged components, or a non-functional system. It's important to identify these key wires:
- Constant Power (often yellow): Provides power to the radio even when the ignition is off, maintaining memory settings.
- Accessory Power (often red): Powers the radio when the ignition is in the accessory or 'on' position.
- Ground (often black): Completes the electrical circuit.
- Illumination (often orange or grey/orange): Dims the radio display when headlights are on.
- Speaker Outputs (various colors): These wires carry the audio signal to each individual speaker.
The importance of correctly identifying and connecting these wires cannot be overstated for a successful and safe installation. A typical aftermarket radio installation kit will often include a wiring harness adapter that mates with the factory WRX harness, simplifying the process. However, you will still need to refer to the 2016 Subaru WRX radio wiring diagram to match the wires from the adapter harness to the wires of your new head unit. The diagram typically looks something like this:
| Wire Color (Factory) | Function |
|---|---|
| Yellow | Constant Power |
| Red | Accessory Power |
| Black | Ground |
| Orange/Grey | Illumination |
| Blue | Antenna Power/Amp Turn-On |
| White (Left Front +) | Left Front Speaker Positive |
| White/Black (Left Front -) | Left Front Speaker Negative |
