Well definitely the Focals at the front, (components). You dont need four full range speakers unless you watch films or the speakers are for the rear seat passengers. I didn't want to lose the boot space so used Genesis 6X9 free to air subs in the rear parcel shelf. Probably at least as good as one 10" enclosed sub in the boot of a saloon. YMMV sound deadening in the doors makes a lot of difference if you aren't too anal about weight reduction. The Genesis are newish speakers so most shops haven't even heard of them. The shop that fitted mine is a Genesis dealer and they haven't but now they're convinced.
