Purpose and fitment

The cover has been designed specifically for Audi S7 and A7 models of the 4G generation as part of the factory-fitted BOSE sound system in the front right door. The construction is prepared for standard mounting points, ensuring that installation is straightforward and does not require any modifications to the upholstery or the door structure.

Precise fitment with the door panel allows for a consistent interior look, which is particularly important in premium vehicles where both functionality and visual continuity of decorative elements are essential.

Construction, color and acoustic function

The speaker cover features a design tailored for the BOSE system, meaning it has a properly shaped surface and perforation that promotes optimal sound flow. The black color allows for harmonious integration with most Audi S7 / A7 interior configurations without introducing contrasts inconsistent with the factory design.

The element serves both a protective and aesthetic function: it secures the speaker diaphragm against accidental impact, dust, or minor debris, while visually organizing the entire lower section of the door upholstery.

Condition, origin and benefits of using OEM parts

The product comes from the line of original Audi components, which ensures compliance with factory dimensional and material standards. As a used part, it retains the mounting parameters specific to an OEM element, facilitating the replacement of a damaged or missing cover without the need to adapt aftermarket replacements with uncertain geometry.

Using an original cover in the factory location helps maintain the visual consistency of the interior, reduces the risk of unwanted resonances, and preserves the acoustic characteristics intended by the audio system manufacturer.

Practical application and replacement scenarios

The speaker cover in the front right door is particularly exposed to mechanical damage during daily vehicle use – entering, exiting, or transporting items in the cabin. Replacing it with a functional part allows you to:

• restore the aesthetics of the door upholstery after the factory cover has been cracked or scratched,
• protect the BOSE speaker from further damage,
• maintain a uniform look for all decorative interior elements.

For users who care about the visual condition of the vehicle and the proper operation of the audio system, installing a correctly matched cover is a simple and effective way to tidy up the door area.
