Chicago94Z28

I have a 94 Z-28 with the Bose system. It is a great system but the CD player stopped working and I am gonna get an aftermarket head unit. How can I hook up rear speakers with my new unit and still use the Bose sub? And does this system already have an amp or should I put one in. I am new to the whole car audio thing. I usually like to hear my engine but recently i love to just crank any kind of great music.
