Good start! Get the head unit and the front soundstage set. Then if you decide you need more lower end (bass) which you prob will, you can add a sub for the bottom end. Now as to rear speakers, you can add them later BUT you dont need to run them full range (50hz~20,000hz) you can use them for midbass. I run 2 inifinity kappa 62.5i woofers only and filter them from 90hz~250hz. The Z32 has a incredible soundstage using the stock speaker locations with just a bit of tuning the front speakers and you dont have to get wild with a subwoofer array to get good bottom end. One quality sub in the right enclosure can be more then enough for casual listening and sound competitions.
