When people are talking about car stereo systems - or any stereo systems for that matter - they tend to miss out on the big picture. People focus on one particular aspect of car audio. Usually, it is the speakers. Most people who are getting expensive car audio systems are young people. They want big, loud, and low. The bigger, the louder, and the lower, the better. Although it is possible to get some really tremendous booming sound with car subwoofer speakers, just having the speakers doesn't give you a good car stereo system. If you want really good sound, you can't neglect any aspect of it. The receiver, the speakers, the wiring, and even the car design play some role in it.
