57 Plate Fiesta Door Speaker help please.

[Tibs]

Been trying to help a mate with his Fiesta Zetec S, and upgrading his front door speakers.

Any help welcome on this from the Ford boys and girls.

What size apeakers have been used by people? We have 165mm upgrade speakers for the car, as we were advised that these are 'listed' for it, but the mounting holes are nowhere near and the likes of Autoleads do not do an adaptor plate for it.

Any ideas on this folks?
