Automotive audio system
First Claim
1. An automotive audio system comprising:
- an amplifier housing including a plurality of amplifier slots and a plurality of amplifier sockets each associated with one of said amplifier slots;
a plurality of amplifier components inserted within said amplifier slots, each component including a plug end fitting within one of said amplifier sockets when said component is installed within the associated amplifier slot;
an amplifier output circuit including speaker output terminals electrically connected to said amplifier sockets;
a controller housing including a plurality of controller slots and a plurality of controller sockets each associated with one of said controller slots, said controller housing further including audio signal bus means for delay-chaining said controller sockets together enabling an audio signal to be serially routed to said sockets;
a plurality of signal processing components insertable within said controller slots, each component including a plug end fitting within one of said controller slots when said component is installed within the associated controller slot, said signal processing components being physically interchangeable within said controller slots;
a communications bus within said controller housing and connected to said controller sockets enabling communication with components plugged into said controller sockets; and
a controller component within said housing and connected to said communications bus, said controller component including means for determining the location and type of signal processing components installed within said controller slots, said controller component including means for configuring said system in response to said determined signal processing components, said controller component further including means for issuing control signals to said determined signal processing components.

Abstract
A modular automotive audio system includes a controller housing and an amplifier housing to be mounted within the vehicle trunk and a remote control for use within the passenger compartment. Modular signal processing components are received within the controller housing, and modular amplifier components are received within the amplifier housing. A controller module within the controller housing provides control for all signal processing components. The controller module polls all positions within the controller housing to determine which components are installed, and then the controller module configures itself via software to provide the control functions. Optionally, non-audio electronic components can also be received within the controller housing for common control by the system.
