Are you an Audi S4 owner looking to upgrade your sound system? One crucial component is the amplifier, which can greatly enhance your audio experience. However, installing an amplifier can be quite challenging, especially when it comes to the wiring. That's why we've created this ultimate guide to B8 Audi S4 amplifier wiring diagram to help you navigate through the process with ease.
Understanding the Basics of Amplifier Wiring
Before we dive into the wiring diagram, it's essential to understand the basics of amplifier wiring. The amplifier is responsible for boosting the audio signal coming from your head unit to the speakers. The wiring involves connecting the amplifier to the head unit, speakers, and power source.
When it comes to amplifier wiring, there are two types of configurations - series and parallel. In a series configuration, the speakers are wired in a chain, while in a parallel configuration, they are wired side by side. The type of wiring configuration you choose will depend on the number of speakers and the impedance rating of your amplifier.

Step 1: Disconnect the Battery
The first step in any wiring process is to disconnect the battery to avoid any electrical shock or damage. Locate the battery and disconnect the negative terminal using a wrench.
Step 2: Remove the Head Unit
The next step is to remove the head unit from the dashboard. You can use a trim removal tool to pry off the trim panel and unscrew the head unit from the dashboard. Be sure to disconnect any wiring harnesses before removing the head unit.
Step 3: Connect the Power Cable
The power cable is responsible for supplying power to the amplifier. Connect the power cable to the positive terminal of the battery and run it through the firewall to the amplifier's location. Be sure to use a fuse holder to protect the amplifier from any electrical damage.
Step 4: Connect the Ground Cable
The ground cable is responsible for grounding the amplifier to the chassis of the car. Connect the ground cable to a metal surface near the amplifier's location, such as a seat bolt or metal bracket.
Step 5: Connect the Remote Cable
The remote cable is responsible for turning on and off the amplifier. Connect the remote cable to the remote turn-on wire of the head unit. You can use a wiring harness adapter to make the process easier.
Step 6: Connect the RCA Cables
The RCA cables are responsible for transmitting the audio signal from the head unit to the amplifier. Connect the RCA cables to the preamp output of the head unit and the input of the amplifier.
Step 7: Connect the Speaker Wires
The speaker wires are responsible for transmitting the audio signal from the amplifier to the speakers. Connect the speaker wires to the output of the amplifier and the input of the speakers. Be sure to use the appropriate wiring configuration - series or parallel - depending on your amplifier's impedance rating.
