Dash speakers upgraded today. Pleased with the sound enhancement. I don't have B&O.
I used the Dayton Audi speakers as per this Audi World forum post
The author of the post does adapter kits that come with all screws and plug connectors (with capacitor for the high frequency). Sent from USA was $81.20 USD for the kit. Probably a bit over the top pricewise but its well made and I definitely couldn't cut something so precise or have access to a 3D printer.
2 x 8ohm speakers for left and right sides
1 x 4ohm for the center.
Hoping to finish the full speaker upgrade soon as I have some Focals 16.5cm for the rear doors and Audison 20cm for the fronts.
