If you’re planning on upgrading the head unit in your 2016 WRX, it’s important to have a good understanding of the wiring diagram. The head unit is the centerpiece of your car’s audio system and it’s responsible for controlling all the sound output. In this article, we’ll break down the wiring diagram and explain how each component works.
What is a Head Unit?
The head unit is the control center for your car’s audio system. It’s the part of the system that you interact with and it’s responsible for sending signals to the amplifier and speakers. The head unit is also where you can control things like the volume, bass, treble, and other equalization settings.
In the 2016 WRX, the head unit is located in the center console and it’s connected to the amplifier and speakers via a series of wires. These wires carry the audio signals from the head unit to the amplifier and then on to the speakers.
How Does the Head Unit Work?
The head unit works by receiving audio signals from various sources like the radio, CD player, or an external device like a smartphone or MP3 player. Once the head unit receives the signals, it decodes them and sends them out to the amplifier as an analog signal. The amplifier then amplifies the signal and sends it out to the speakers.
The head unit is also responsible for controlling the equalization settings. These settings allow you to adjust the volume, bass, treble, and other sound characteristics. The head unit sends these settings to the amplifier and the amplifier then applies them to the signal before sending it out to the speakers.
