Purpose and vehicle placement

The presented rear tweeter is designed for installation in the rear part of the vehicle, with the possibility of mounting on either the left or right side. This solution allows for flexible use of the component during audio system repairs – it can be used on either side, in accordance with the factory configuration of a specific vehicle. Its placement in the rear cabin area is responsible for completing the soundstage and improving the clarity of high frequencies for rear passengers.

Technical and functional characteristics

The rear tweeter in this model is responsible for reproducing higher frequency bands, which translates into better sound detail – clearer vocals, instrument details, and overall sound transparency. The construction is adapted to the factory Mercedes sound system, which ensures that:

• compatibility with the original electrical harness is maintained,
• there is no need to use additional adapters,
• acoustic parameters are consistent with the other speakers in the vehicle.

Such a fit reduces the risk of improper audio system operation and allows for maintaining a predictable, stable sound throughout the interior.

Benefits of using an original Mercedes component

Using an original rear tweeter in a Mercedes car allows you to maintain the factory sound quality standard without the need to modify the installation. The main advantages include:

• factory fitment with the mounting location in the rear of the body,
• preservation of the original acoustic characteristics of the audio system,
• reliable electrical matching to the vehicle's installation.

For the user, this means faster installation, no interference with the wiring harness, and a lower risk of unwanted interference or sound distortion.

Condition and service application

The item comes from the Parcel shelves and covers category, which in practice means it is intended for installation in the rear zone of the vehicle, in the immediate vicinity of the luggage compartment or rear shelf – depending on the specific body configuration. It works well both for point replacement of a damaged tweeter and for a comprehensive refresh of the factory sound system in Mercedes models with the V177 body type.
