Enhancing the sound quality in your Audi A4 B5 Sedan, produced from 1995 onwards, is not just about replacing old speakers—it’s about upgrading to a superior audio experience. If you’re looking to breathe new life into your car’s audio system, a comprehensive speaker upgrade is essential. This article details the process and benefits of installing a 300-watt sound system with top-notch components for the Audi A4 B5.


Understanding the Existing Setup

The Audi A4 B5 Sedan originally comes with a 130mm 2-way front speaker system, including external tweeters in the front doors. The rear doors house 165mm full-range speakers, and in the sedan variant, there are two additional 165mm full-range speakers in the rear shelf. Over time, these factory speakers degrade due to exposure to moisture and temperature fluctuations, leading to diminished sound quality.


Why Upgrade?


Replacing the worn-out factory speakers with high-quality aftermarket options significantly enhances sound clarity and volume. The Audi A4 B5 speaker upgrade package includes the Hertz DSK 130.3 2-way front speaker system with external tweeters for the front doors, and Hertz DCX 165.3 2-way coaxial speakers for the rear doors and rear shelf. These speakers deliver up to 300 watts of maximum power and have an impressive sensitivity of 93 dB, ensuring loud and clear audio playback even from the factory radio.


The Upgrade Package


The upgrade package is designed to fit seamlessly into the Audi A4 B5, providing all necessary components for a straightforward installation:


  • Front System: 130mm 2-way speakers with external tweeters and crossovers.
  • Rear System: 165mm 2-way coaxial speakers for both rear doors and the rear shelf.
  • Mounting Hardware: Vehicle-specific mounting rings and adapter cables to ensure a perfect fit.
  • Connection Adapters: Included for connecting the new speakers to the existing car wiring.


These high-quality speakers are designed to handle higher power levels and deliver more detailed and dynamic sound, significantly improving the overall audio experience in your vehicle.


Installation Tips


Replacing the speakers in the Audi A4 B5 is relatively straightforward for those comfortable with DIY projects. The process involves removing the door panels, which are secured with screws and clips. It’s important to note that simply removing the speaker grilles is not sufficient as they are fixed to the door panels.


Our website, auto-lautsprecher.eu, offers a detailed guide with step-by-step instructions for installing the new speakers in your Audi A4 B5. This guide is available in the Auto Lautsprecher Einbau-Tipps section, providing valuable insights and tips to make the installation process as smooth as possible.


Additional Tools and Recommendations


To assist with the installation, our webshop also offers a set of plastic prying tools that help safely remove the door panels without damaging the clips. Additionally, we recommend using self-adhesive aluminum-bitumen mats for door insulation. These mats improve the vehicle’s acoustics by reducing vibrations and enhancing bass response, providing a more immersive audio experience.




Upgrading the speakers in your Audi A4 B5 Sedan with high-quality systems from brands like Hertz significantly improves the sound quality, offering greater volume and clearer audio reproduction. This upgrade not only enhances the music listening experience but also provides a more detailed and dynamic representation of vocals and instruments.
