Abstract
In vehicle audio entertainment systems are fitted to most new vehicles and are considered one of the most important car accessories. Primarily, car audio sound systems are designed to fill the enclosed vehicle cabin space with sound at moderate sound pressure levels sufficient to allow for listening pleasure and to reduce the intrusion of road and vehicle( related sounds at open road cruising speeds. Over recent times a trend has developed whereby high power sound systems are being installed in some vehicles by audio enthusiasts which provide high interior sound pressure levels, with ensuing effects on exterior vehicle noise levels
