I have the Bose system, the car I test drove had the standard system, I like the upgraded system better. Some members of this forum and the Csportscoupe forum have flamed the Bose System. A lot of the people who own these cars are 20 and under and they’re looking for Super Mega Ultra Bass, I listen to Blues, Classical, Jazz, and Rock and find the Bose sound very good. I also consider a car to be the most imperfect listening space there is, so $600 or $700 is all I would ever consider for a car sound system.
