Replacment speaker help

[Painted Pilgrim]

I've taken some kit out of my Defender which I'd like to reuse in the T5 if I can, The main thing being the Focal ibus 2.1 sub/amp which I'm going to fit under the drivers seat.
Could anyone tell me what a good speaker kit for the front would be please to run of the focal ibus? From what I' ve read the speaker set up is different to a standard T5? and there is tweeters in the dash?
I also have the focal es100 k speakers with crossovers and tweeters I'm wondering if I can use, maybe in the back locker??
Any help much appriciated
