Upgrade Your Subaru WRX Headunit for an Epic Audio Experience: A Comprehensive Guide

As a Subaru WRX owner, you know that the stock headunit is nothing special when it comes to audio quality. If you are looking to turn your daily commute into a concert experience, upgrading your car’s headunit should be on top of your list. In this comprehensive guide, we will walk you through all the steps needed to upgrade your Subaru WRX headunit and achieve the audio quality you deserve.

Types of Headunits Available for Subaru WRX

Before diving into the installation process, it is essential to choose the right headunit for your car’s audio system. There are several types of headunits available in the market, each with its own features and price point. Here are some common types of headunits compatible with Subaru WRX:

  1. Single-DIN Headunit: This type of headunit is the standard size and fits most cars, including the Subaru WRX. It comes with basic audio controls, AM/FM tuner, and a CD player.

  2. Double-DIN Headunit: If you are looking for more features and a bigger display, a double-DIN headunit may be the perfect choice for you. It can fit into the same space as a single-Din headunit, but with a larger touchscreen display, Bluetooth, Apple CarPlay/Android Auto, and more advanced audio controls.

  3. Navigation Headunit: If you are always on the road and need a reliable GPS system, a navigation headunit would be a good investment. It comes with built-in GPS software, real-time traffic updates, and other advanced features.

  4. OEM Headunit: If you prefer to keep the factory look of your Subaru WRX, you can opt for an OEM headunit. These headunits are designed by the car manufacturer to match the car’s interior, but they come with limited features compared to aftermarket headunits.

Compatibility with Subaru WRX Wiring

Once you have chosen the right headunit for your Subaru WRX, it’s essential to make sure that it is compatible with the car’s wiring.

You can either hire a professional installer or do it yourself if you have some knowledge of car stereo installation.

Installation Process

Before starting the installation process, make sure that you have all the necessary tools and equipment, including a wiring harness, mounting kit, and any additional adapters. Here are the general steps to follow when installing a new headunit in your Subaru WRX:

  2. Remove the old headunit by unscrewing the mounting bolts and unplugging the wiring harness.

  3. Connect the new headunit’s wiring harness to the car’s wiring harness using crimp connectors or soldering.

  4. Place the new headunit into the mounting kit and secure it with screws.

  5. Reconnect the negative battery cable and turn on the new headunit to test if it’s working correctly.

  6. If everything is working fine, connect any additional audio components like speakers and amplifiers.

Troubleshooting Common Issues

If you encounter any issues during or after the installation process, here are some common problems and their solutions:

  1. No sound coming from the speakers: Check the wiring connections and make sure that all cables are properly secured.

  2. Touchscreen not working: Make sure that the touchscreen cable is correctly connected to the headunit.
