that telling someone he has shitty taste is somehow equivalent to infringing upon his personal freedom. It's not. Putting sub enclosures and 50 speakers in the interior of a car is something generally done by lower income people (basically, young people)...same goes for ''body kits" and the like. Used Z's are now in the hands of lower income people, hence the proliferation of ugliness. At least thats the operating theory here.
In any case, nobody is telling him he can't do it. So stop whining.
