Anybody who knows?: I have a 3 door mk6 fiesta zetec. I would like to know some things; what size are the four speakers in it? how easy are they to replace? is the facia for a cd player from autoleads available to take two DIN size products (eg CD player and monitor?) or is there another that does? What size wheels can you get on without having to make mods to arches and with which I don't have to worry about clearance. And finally Has anyone fitted an induction kit? how easy is it? thanks
