Kenwood custom speakers in Arosa

[Smeagol]

Kenwood have a set of speakers marked as compatible with the Arosa, model KFC-P723EC. they look as if they need the tweeter surround to be taken out completely and I`m not sure how they fit the door speakers.

Anyone had any experience of these? How easy were they to fit etc.

Tried local Kenwood dealers and they had none in stock so I could look at them.

thanks
