So you are saying the speakers in the doors for a Ford Fiesta have a Ford Pt No on them how weird?The door speakers were never B&O anyway so it's more honest to leave them without a logo.
There's a thread somewhere where someone has pictures of the speakers and the speakers are stamped with a Ford logo. I remember noticing that the Ford website has very careful language in the marketing material for the system too - they never mention that the speakers are actually B&O but more that the system is B&O tuned and things like that, which implies that B&O might have been more involved in the design and tuning of the soundsystem as opposed to actually supplying higher quality components.
Fwiw - I'm not sure if the center speaker or subwoofer are actually genuine B&O parts. They could be but I doubt it.
The soundsystem is pretty decent in my opinion for a small, relatively cheap car, but it uses standard cheap speaker drivers and in that regard it's a bit of a scam.
