Will focal 165A components be ok for my Fabia VRS - 66mm deep?

Hi folks, I've noticed the rear tweeters especially on my fabia are breaking up at moderate volume and the sound in general isn't that great. I have a good alpine head unit installed but want to upgrade the speakers. Having had a wee search it seems depth is an issue and I'm not sure the focal 165A components I was going to get will be ok. The mid is 66mm deep and I don't know the size of the tweeters but presume there is not much of an issue fitting them to the oe slots. Are both front and rear speakers 165mm components? Hope you can help!
