Sound System/Head Unit

Ok I plan on bying a 08 or 09 mazda speed 3 and needed some advice what i should do with the stero, sound, etc. I actually already bought a amp, sub, ad head unit. The store was closing down so I decided to get them since they were so cheap. Do you think the car would need any more power with Bose package? If I install what I own if they actually work, would it voi my warranty?
