Rear speaker size

[kaptain_k]

apologies if this has been brought up but I did a search and just seemed to get very confusing results, I want to replace my rear speakers because i've blown the origionals, does anyone know what size they are to replace? I've got one out but I don't know whether to measure the cone or the whole bracket?

any help appreciated.

from memory there 6.5", pretty sure your meant to measure across the brackets from the centre of each hole which i have just done and got 6.5"
