You must be a tall guy with long legs and have the front seat back towards the rear. On the other hand, my legs are short so I seat close to the steering wheel. I'm getting my Infinity's tomorrow and plan on swapping out only the fronts. I already have the fader putting the sound mostly upfront, as I don't have rear passengers very often.
Nope! Only 6' with regular legs. I am tall in torso so I do lean back a bit, as well as a former musican so that might have somethng to do with it. Point is, replacing the the two front speakers wouldn't cut it for me. I did that once in an older car I had and the difference in quality between the fronts and the rears annoyed the hell out of me.
