The GLADEN SoundUp MB-177-SUB is a plug-and-play sound upgrade designed specifically for Mercedes-Benz 177 series vehicles. Designed to enhance the standard sound system, it does so without altering the vehicle's structure or the original wiring harness.

The upgrade focuses on two key steps:
First, the tweeters are replaced with high-quality components. Second, an integrated 12 dB crossover ensures clean separation and controlled interaction with the existing system. The result is significantly better resolution, greater clarity, and more precise reproduction of voices and details.

Second, the kit adds a subwoofer to the system and integrates it into the OEM installation area. This creates a more stable foundation with greater depth, pressure, and control without altering the interior or sacrificing space. The bass sounds more confident and blends harmoniously into the overall sound, especially with modern music and higher volumes.

The integration is vehicle-specific and retrofittable. All components are tailored to the 177 series installation situation, allowing for clear, service-friendly, and vehicle-friendly installation.
