Abstract
Abstract A standardized chassis for installation of a sound system in an automobile is adapted to receive a component selected from one or more of several groups of components to permit variations in complexity and quality of the composite automotive sound system commensurate with the desires of a user. A face plate, selected from a group of face plates and conforming with the requirements of the components selected, is attachable to the chassis and provides an aesthetically pleasing appearance. The chassis and components include wiring harnesses interconnectable with one or another to eliminate all chassis external leads other than leads for the antenna, electrical power and speakers.
