The GLADEN SoundUp BMW S676-BASIC-C is a plug-and-play sound upgrade designed specifically for BMW models with a factory-installed hi-fi sound system (optional extra 676) and center speaker. Designed to improve the sound of the standard hi-fi system without requiring complex modifications to the vehicle, it delivers noticeable results.

The set focuses on replacing the front speakers with high-quality GLADEN components. This significantly improves detail resolution, dynamics, and precision in the front area. Additionally, the center speaker is actively controlled and integrated into the sound image.

This creates a more stable soundstage with a clearer focus on voices and central sound components. The result is a cleaner, more balanced sound that is particularly impressive for the driver and front passenger.

The integration process uses vehicle-specific plug-and-play cable sets so the original wiring harness remains intact. Installation is straightforward, reversible, and gentle on the vehicle while continuing to use the existing hi-fi signal structure.

The SoundUp BMW S676-BASIC-C is the ideal solution for anyone looking to significantly upgrade their BMW's hi-fi system, offering a clear front stage, enhanced speech intelligibility, and precise spatial representation.
