China Wholesale Car Audio

Car audio is a term used to describe the sound system fitted in an automobile. A stock car audio system refers to one that was specified by the manufacturer when the car was built.
The most common and familiar piece of audio equipment is the radio / tape player / CD player / DVD Player which is generically described as a Head unit, which also can be called a head deck, after older tape decks. It is also the most likely component to be upgraded with an after market item. A recent development in head unit technology has been the addition of CD players with MP3, Ogg(a standard format which allows digital multimedia such as podcasts to be streamed efficiently over the internet), WMA, AAC, and USB, Wi-Fi support. Even with the rampant ubiquity of solid state MP3 players, car audio systems with line-in jacks and other standards are only in their infancy, and that since tape adaptors are often used with tape players, people are now viewing car radios with built-in CD players as "misfeatures" of the audio system since people now often "rip" their CDs onto their computers. Other types include the video touch screen capable of controlling; navigation, DVD movies, mp3 players back up camera and other accessories.
Most modern cars include at least a CD player / CD recorder, and some have the option for a CD changer, which holds multiple discs either in the head unit itself or in a separate unit usually located in a trunk or console.
