Purpose and vehicle placement

The presented speaker is a component mounted in the rear part of the vehicle, within the door trim. The design is intended for installation on both the left and right sides, which facilitates the selection of the correct component during service or replacement of a damaged speaker.

Thanks to its compatibility with the factory Bose system in the Audi A7 4G, the speaker maintains the appropriate acoustic characteristics, and its installation does not require interference with the electrical system or modification of wiring harnesses.

Technical specifications and integration with the Bose system

The speaker has been designed as part of an integrated Bose sound system, which means its parameters are adapted to work with the factory amplifier and other transducers in the vehicle. Properly selected impedance, efficiency, and frequency response allow for maintaining tonal balance between the front and rear of the cabin.

Such matching translates into:

• stable, controlled reproduction of mid and selected low frequencies in the rear of the interior,
• no need for additional system calibration after replacing the component,
• maintaining sound consistency with the other Bose speakers in the vehicle.

Installation within the door trim

The speaker is designed for installation within the Door trim, which allows for aesthetic integration with the factory interior finish. The construction is intended for mounting in the original attachment points, making the replacement process predictable and possible to perform in a standard service or a workshop specializing in the Audi brand.

With proper installation, the tightness and rigidity of the door panel are maintained, which is important both for sound quality and for eliminating unwanted resonances and rattles while driving.

Product condition and benefits of using a used part

The offered speaker comes from the used parts group, which allows for an economical repair of the audio system while maintaining the manufacturer's original specifications. Using a component from disassembly enables the maintenance of installation consistency, without the need to use replacements with uncertain parameters.
