As long as you use the zenclosure spacer rings any 5 to 6 3/4 would fit your z most just use 6.5. The polk db series are able to be ran off your stock head unit but if you are going to run higher end component speakers you might want to think about getting a amp.
But you will hav to either cut out or make a bracket for your new 1 inch tweeter up on your dash but it goes in the factory location.
