Car audio has expanded from a market that originally consisted of simple radio-cassette and CD players to one which now includes MP3 players, iPods, DAB Digital Radio, DVD players, speakers, subwoofers, amplifiers and more.
Car Audio Equipment
Traditional stereo systems consist of a main head unit fixed in the dashboard of the car, with speakers attached. A standard head unit generally includes a radio and cassette player/CD player.
However, the latest generation of in-car head units now come with a whole host of features including CD players/changers that can handle CDs 'burned' on a home PC, including playback of MP3 files, sleek LCD displays, built-in Bluetooth connectivity, a DAB digital radio turner, USB ports and an SD/MMC card reader.
Most stereo systems are also compatible with MP3 and iPod players, while the most expensive high-end units even come with a fold-out DVD player with touchscreen display and built-in satellite navigation.
In terms of sound, many car stereos now include a sophisticated equaliser, an active crossover, surround sound processor and other digital tricks, in addition to simple tone controls, to provide excellent audio quality.
