Purpose and vehicle placement

The presented speaker is dedicated to installation in the rear right part of the cabin, which allows for the precise reproduction of the soundstage intended by the vehicle manufacturer. Its placement in the rear axle zone on the passenger side ensures proper acoustic coverage for passengers sitting in the back, while maintaining balance between the left and right sides of the audio system.

Thanks to the factory design, the speaker installation does not require any modifications to the upholstery or electrical wiring – the component is ready to work within the existing Mercedes sound system, which reduces the time and complexity of service work.

Technical and functional characteristics

The speaker has been designed as an integral component of the Mercedes audio system, taking into account the electrical and acoustic parameters specific to this model. Properly selected frequency response and tuning with other transducers in the vehicle allow for consistent, comfortable sound without distortion or unwanted resonances.

Key benefits of using the original rear right speaker:

• preservation of the factory sound characteristics in the rear of the cabin,
• secure fit to factory mounts and wiring harnesses,
• stable operation under automotive operating conditions (temperature changes, vibrations),
• consistent appearance with other interior trim elements.

Integration with interior and decorative elements

The speaker works with elements from the Cladding, trim strips, and decorations group, ensuring that after installation, the whole remains aesthetically integrated with the door upholstery or body panel. The properly selected shape of the basket and grille (if provided in the given equipment variant) allows for maintaining a uniform stylistic line of the Mercedes interior, without visible modifications or non-factory adjustments.

Such a solution is particularly important in premium class vehicles, where visual and acoustic consistency has a direct impact on perceived driving comfort and the vehicle's value on the secondary market.

Component condition and service application

The offered speaker comes from the original used parts segment, which allows combining compliance with factory specifications with a more favorable repair cost compared to new components. It is a practical solution both for workshops specializing in the Mercedes brand and for users who independently maintain the technical condition of their car.

The element will prove useful in situations such as:

• repair after mechanical damage or flooding of the factory speaker,
• restoring full functionality of the audio system after interruptions in the rear right channel,
• replacing a missing component after previous non-factory interior modifications.
