Description

This bracket was designed for a friends Audi B5 S4 Bose door speakers, this is for the front left door mounted speaker (mirror the model for the right side). The adapter allows a replacement speaker with a standard mounting method to be fitted. I do not know if this would fit a normal A4 or one without the Bose Speakers. I also do not know if there were any regional differences. The stock speakers use a propriety mounting system which wont take any standard size speakers. The speakers this was designed for can be seen here: The dimensions of the speaker fitment can be seen in the images. The groove in the face which touches the door card is designed for the TPU insert to prevent rattles, this could probably also just be filled with silicone or resin.
