Purpose and vehicle placement

The presented speaker is designed for installation in the rear doors, on either the right or left side. This placement allows for a balanced soundstage in the cabin and proper distribution of the audio spectrum between the front and rear of the vehicle. The component is compatible with the factory electrical installation and door structure, facilitating installation in the location specified by the manufacturer.

Construction and integration with door trim

The speaker has been designed as part of the system mounted within the Door trim, ensuring it fits original mounting points without requiring any modifications to the panels. The basket design and mounting points are adapted to the factory holes in the doors, which minimizes the risk of improper fitment and unwanted resonance.

The factory connector geometry allows for connection to the wiring harness without the need for soldering or adapters. This solution helps maintain stable electrical and acoustic parameters throughout the entire sound system.

Performance characteristics and installation benefits

As an original audio system component, the rear door speaker for W212 and W218 models provides:

• consistent sound quality with other speakers in the vehicle,
• correct impedance matching for the factory amplifier or head unit,
• stable mounting within the door structure, reducing unwanted vibrations,
• preservation of the factory interior character without interfering with the upholstery.

By using an original component, you can restore the proper operation of the rear audio channel after a speaker failure, without the risk of compatibility issues or degradation in sound quality.

Component condition and service application

The speaker comes from the secondary market, making it an attractive service solution for users looking for a factory component at a reasonable price. This type of part is suitable both for replacing a damaged speaker and for restoring the completeness of the sound system after previous modifications or disassembly.
