Replacement Orion Ghia Si speakers

[TheRedOnion]

Hi All,

I have a J reg Orion Ghia Si that is in need of some replacement speakers all round. I have the boot version not the hatchback so the rear speakers are not of a standard size. Does anyone know of suitable speakers that I will be able to fit in place of the Ford ones? As I understand it I can replace the front ones with standard 10cm ones if I get some adapters, hopefully they won't get in the way of the windows though!

I'm not after anything boy racer-ish, just something half-decent to replace the crackly buggers that are in there at the moment.
