Fabia front speaker's size

Hi,

I'm an italian boy, I'm sorry for my bad english.

I'm looking for some information about front speaker size of skoda fabia.

There is problem of depth?

I'd like to install Focal 165 a1. Can I put a 25 mm tweeter in the original predisposition?

how much deep must be the woofer?

howmuch large must be the tweeter?

Thanks

Excuse me for my english, but I'v not found information on italian web site

Thanks

Cristian
