Installation Guide Introduction

This installation guide is designed to help you upgrade your Mercedes-Benz C-Class W205 / C205 Coupe and GLC X253 with the 3D Rotating Tweeter Speaker system in a safe, efficient, and OEM-style way.

The 3D rotating tweeter speakers are engineered to replace the original factory tweeters while maintaining a seamless fit with your vehicle’s interior design. Once installed, the system enhances both sound performance and visual appeal, especially when paired with ambient lighting functions on compatible models.

Depending on your vehicle configuration, installation may vary slightly:

• Vehicles with factory ambient lighting can achieve full system synchronization through the original COMAND interface.
• Vehicles without factory ambient lighting or upgrading from 3-color to 64-color require additional OBD coding to activate the ambient light menu after installation.

This guide will walk you through each step of the installation process, including component identification, removal of factory parts, proper wiring connection, and final system testing to ensure everything functions correctly.

Before starting, please confirm your vehicle model compatibility (W205 / C205 / X253, model years 2015–2022) and ensure all necessary tools are prepared for a smooth installation process.
