When we say car stereo, it would of course automatically mean that you would have to have car sound setup done to your vehicle. If you really want things to go great in terms of sounds, make sure that you do something with the head unit. As much as possible, get one that has CD players rather than cassette players for better sound. It should only cost you around $200 for a nice player. Another to remember is to make sure that the speakers produce sounds where they should. Call a mechanic to adjust your front speakers to crossover and blast 2 kHz instead of having the back speakers sounding louder. This way, you could enjoy the sound better. But the main important thing that you have to remember is to install a good security system for your car because no matter how good of a system you may have, the moment that crooks decided to take them, it would just be a waste of time and money on your end.
