You gotta have speakers in the back! When you back the car up in a parking lot and all your friends are there, you open all the doors and blast the music! Only 2 front speakers would be terrible!
I can only speak of what I know, I have 4 alpine 5x7s in the doors and they sound beautiful. I couldn't be happier. I bought them for around $110/pair. Another guy in a different thread said he found infinities for $79/pair. I have never heard infinities so I cant say if they are good or bad...anyway good luck!
