Let me rephrase: 4 way, 5 way, etc coaxial speakers are unnecessary. They will never sound like a good set of components. I'd take a 2 way component set over a 4 way coaxial any day.

Not even close to the same thing. Surround sound systems have that many speakers because each speaker has its own discrete channel and produces sounds independent of eachother. It'* meant to create realism and "put you in the action."
Music is meant to be listened in stereo with the speakers in front of you. So, really the proper way to put speakers in your car would be to have none at all in the rear (save for the subwoofer, because the low frequencies can't be localized). People who have high quality setups in their homes used for strictly music listening would never have speakers all around them. Like this:
Go look into some SQ setups in cars and see how many use speakers smacked here and there all over the car. They put a lot of time and energy into getting the sound image in the correct spot, and it ain't in the back of the car.
That being said, a lot of people prefer the sound of having rear fill and in the end it'* all about preference. But, that doesn't mean it'* the "right" way.
