Sursa.During the late 80’s, several interests in the car stereo industry promoted the formation of sanctioning organizations to provide common rules and to move the focus to sound quality. The most important of these were CAN (formed by Alpine) and NACA (supported by shop owners and amp manufacturers). Both organizations sanctioned countrywide regional events and hosted National Championship events in the late 1980's. They merged to form IASCA in 1990. Despite the move to "quality" based judging, volume was still a significant portion of most early 1990's competitions. Since then, he two styles -- SPL vs. sound quality -- have become almost mutually exclusive. The loudness competitions have become known as dB drag racing. Currently, MEASQ conducts Sound Quality Competitions nationally in Australia. This back to basics competition format was developed by Marc Rushton, the founder of one of the largest enthusiast organisations known as Mobile Electronics Australia.
