Competition Hertz : the culture and practice of car audio competitions

The present paper explores extreme car audio systems and the culture and practices that surround car audio competitions. I begin by examining whether, and how, car audio can be thought of as a 'music scene' and in what ways the culture and practice of car audio may fit within post-subcultural discourses. Following this, I offer a description of car audio competitions, revealing some of the practices that define this aspect of car audio scenes. In particular, I concentrate on sound pressure level (SPL) competitions and some of the interesting aspects of the SPL scene. Finally, I briefly examine how the powerful effects (and affects) of bass frequencies are an important part of the attraction of loud car audio systems and how car audio systems contribute to the territorializing of urban spaces.

Portrait of Heinrich Stahl (1868-1942 ).

H.Stahl was the last president of the Jewish Community in Berlin. He is seated in a chair with wooden arm supports. He seems a small man, an impression emphasized by a large expanse of plain, tan background. The facial expression is tense, with deeply furrowed brows.
