OK guys this is sort of a general question to car audio enthusiasts. It seems to me like every person with an aftermarket stereo with subs I meet is proud of how the subs shake and rattle the whole car. My friend is way into rap and I hate riding in his car because all I can hear is rattling windows and license plates. The thing is that he and almost every other car audio enthusiast I've ever met seems to think that this means they have a good system. I don't understand why they like this. Isn't the whole reason they make stuff like Dynamat and sound deadening kits for license plates because rattling ruins the sound quality of the music? Am I the out of touch on here?
