Cup stereo set-up - advice needed

[The_Notorious_C.U.P]

Got uprated components in the front, 200w amp and bloody awful 6x9's in the parcel shelf. Now before some chav smashes through my back window all for the sake of some £20 6x9's, I need to fit some uprated speakers in the door pods in the back (and obviously get a new parcel shelf!)
Any ideas on what ones are best? Like the loudness of the 6x9's and they handle the bass pretty well but need something a little less in ya face!
Any clues peeps?? :S
