The way I feel about it is this: I put a lot of time and money into designing, planning, and purchasing an audio setup. I want it to sound good inside my car, and that's it. I couldn't care less if the people outside my car can hear it, or how it sounds to them. It wasn't their cash and time that went into building my setup. Being able to hear the music outside is just a byproduct. And, OP, if you are using a sound system to call attention to yourself and to "show off", then you are part of the reason the average citizen complains about loud stereos, and you are part of the reason why there are fines for playing music too loud.
