If you’re planning to upgrade the stereo system in your 2016 Subaru WRX, you’ll need to know the correct wiring diagram to make the job easier. In this article, we’ll provide you with a complete guide on how to install and connect a new stereo in your car.
Wiring Harness
The first step in wiring your new stereo is to get a wiring harness that matches your WRX’s wiring. This will make the installation process much easier and quicker. You can purchase a wiring harness from any car audio store or online retailer.
The wiring harness connects the stereo to the car’s factory wiring, which means you won’t have to splice any wires or make any modifications. It’s a plug-and-play solution that saves you time and reduces the risk of damage to your car’s electrical system.
The wiring harness comes with color-coded wires that match the colors of the wires in your WRX’s factory wiring. Simply connect the corresponding wires to each other, and you’re good to go.
It’s important to note that not all wiring harnesses are created equal. Make sure you get a harness that’s compatible with your WRX’s make and model, and the stereo you plan to install.
Some wiring harnesses may require additional wiring, such as for an amplifier or subwoofer. Be sure to read the instructions carefully and double-check everything before you start connecting wires.
Tools You’ll Need
Before you start, make sure you have all the necessary tools. Here’s a list of what you’ll need:
| Wire cutters/strippers | Butt connectors or crimp connectors | Tape or zip ties |
| Screwdrivers (flathead and Phillips) | Pliers | Socket wrench set |
| Multimeter | Heat shrink tubing (optional) | Trim removal tool (optional) |
Having the right tools will make the installation process much smoother and reduce the risk of damage to your car or stereo.
Disconnect the Battery
Before you start working on your car’s electrical system, it’s important to disconnect the battery. This will prevent any electrical shocks or damage to your car.
To disconnect the battery, simply remove the negative cable from the battery terminal. Make sure it’s safely secured and won’t accidentally come into contact with the battery.
Removing the Factory Stereo
Once you’ve disconnected the battery, it’s time to remove the factory stereo. The process may vary depending on your car’s model and year, but generally, you’ll need to:
- Remove the trim panel around the stereo
- Unscrew any screws holding the stereo in place
- Pull the stereo out of the dash
You may need to use a trim removal tool to remove the trim panel without damaging it. Be patient and take your time to avoid any mistakes.
Connecting the Wiring Harness to the Stereo
Now that you’ve removed the factory stereo, it’s time to connect the wiring harness to your new stereo. Most aftermarket stereos come with a wiring diagram and instructions on how to connect the wires.
Simply match the colors of the wires on the harness to the corresponding wires on your new stereo. You can use butt connectors or crimp connectors to make the connections, and heat shrink tubing to protect the connections from moisture and corrosion.
Make sure you double-check your connections and test the stereo before reinstalling it in the dash.
Reinstalling the Stereo
Once you’ve connected the wiring harness to your new stereo and tested it, it’s time to reinstall the stereo in the dash. Follow the steps you took to remove it in reverse order, making sure everything is securely in place.
Use tape or zip ties to secure any loose wires or connectors to prevent them from rattling or causing any problems. Reconnect the battery once you’re done.
