If it's just for music, the rears are not recommended. Here's my analogy i use everytime. At a live performance either concert/bar, are there ever speakers behind you? Always in front.
By doing this, you can use the money you were going to spend on the rears and buy better components up front or a better amp etc. Upgrading the components will drasticaly improve the sound. Infinity brand tend to be very harsh. I know of a few people that set the crossover to -4. Overall, very good. A lot of people on the 350z boards like them.
Hope this helps. Let me know if you have any other questions.
