Amp rack

Amp rack is short for amplifier rack and is a term used mostly in reference to professional audio applications to describe any furniture, fixture, or case where amplifiers are mounted by their faceplates or in slot grooves, mostly synonymous with rack mount.

Examples include use in recording studios, mobile DJ setups, or live stage events. Each of these instances could require more power or more output channels than a single amp could provide, but necessitate portability of all amps at once.

The term is also sometimes used to describe the mounting fixture of an amp or amps used in car audio applications, though usually not the 19" rack mount variety.

Vehicle audio

Vehicle audio is equipment installed in a car or other vehicle to provide in-car entertainment and information for the vehicle occupants. Until the 1960s it consisted of a simple AM radio. Additions since then have included FM radio, CD players, navigation systems, Bluetooth telephone integration, and smartphone controllers like CarPlay and Android Auto. Once controlled from the dashboard with a few buttons, they can now be controlled by steering wheel controls and voice commands.

Initially implemented for listening to music and radio, vehicle audio is now part of car telematics, telecommunication, in-vehicle security, handsfree calling, navigation, and remote diagnostics systems. It is also used to create fake engine noise. For the 2015 Ford Mustang EcoBoost, an "Active Noise Control" system was developed that amplifies the engine sound through the car speakers. A similar system is used in the F-150 pickup truck. Volkswagen uses a Soundaktor, a special speaker to play sounds in cars such as the Golf GTi and Beetle Turbo. BMW plays a recorded sample of its motors through the car speakers, using a different samples according to the engine’s load and power.

Jim Fosgate

James M. "Jim" Fosgate (born c. 1945 in Indianapolis, Indiana) is an American inventor, engineer and businessman. The self-taught son of a television and radio repairman, Fosgate invented the first car amplifier in 1973 and founded Fosgate Electronics, now called Rockford Fosgate. Since his departure from Rockford Fosgate in 1981, Fosgate has remained active in the audio world, running Fosgate Laboratories and leading the team that created Dolby Pro Logic II. He received a special Emmy for that invention. Fosgate was also the developer of one of the finest quadraphonic decoders, the TATE II 101A (see the SQ section of the article pointed to by the previous link, for details), in collaboration with Peter Scheiber and Martin Willcocks, which was superseded by his 3601 decoder.
