dvd/mp3 setup

i am planning on puttin a panasonic dvd/mp3 deck in my car in the summer time, and my plan is to have 69’s in the front and in the back, i know that the stock speakers in the back are only 4", so is it possible to be able to have 2 69s put in instead? also i want to have just a little 10" sub for a little extra bass, do i need a amp for this??? if i do what kind of amp is good one to get for my setup??
