FIREWARRIOR90

Ok so I want two front components and two 2 ways in the rear. I don't want to have to add a amp or change speaker wire, I just want something more than what's in it. I've seen the infinity primus 6500, are they good? Or for my two rears, could I go with mid drive woofers and a small amp. I will be changing the head unit to a in dash aswell. I want something that can be powered by the head unit really. No I don't want no custom this and that, just want to replace what's there for presentable tunes. So give me some ideas or some speakers that I can pick up at a local best buy or brandsmart. Something that won't hinder the Windows going down. Thanks. Vino
