Automotive audio system
First Claim
1. An audio amplifier system comprising:
- an amplifier housing, said housing including a plurality of pairs of channels opening toward one another and a plurality of sockets each associated with one of said pairs of channels, said housing further including an interior chamber, fan means for moving air through said chamber, and a plurality of air vents permitting air to flow through said chamber when said fan means is operated; and
a plurality of amplifier modules within said housing, each of said modules being uniquely associated with and positioned adjacent one of said air vents, whereby air is moved individually over each of said amplifier modules from one of said air vents when said fan means is actuated, each amplifier module including a one-piece heat sink having a pair of opposed flanges, said opposed flanges on each amplifier module slidably interfitting within a pair of channels in said amplifier housing, whereby said modules may be slid into and out of said housing, each of said amplifier modules further including a circuit card supported solely by the associated heat sink, each circuit card including a plug portion connecting with the associated socket as said component is slid into said housing.

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.
