The sound systems fitted in automobiles can be described by the term of car-audio. Little difference there is in the stock car audio system which refers to one that was specified by the manufacturer when the car is built. On the other side custom car audio installations can involve everything from the upgrade of the radio to a full customization of a car based around its audio equipments like car stereos and CD changers.
The audio equipment commonly used is the radio, tape player, CD player, DVD Player. These are generically described as a Head unit. The addition of CD players with MP3, WMA, AAC, and USB, Bluetooth and Wi-Fi support are new developments in head unit technology.
CD players/ CD recorders have become standard inclusions in most modern vehicles, with the option to add a CD changer, which holds multiple CDs either in the main unit or in the trunk or console. The most common types of CD changers are External Cartridge, Internal Cartridge and Carousel CD changers.
Stereo (short for stereophonic sound) uses two or more audio channels to reproduce sounds to create natural impressions. The idea is that, as with natural hearing, sound appears to come from various directions. Car audio stereos typically use two channels, each providing data for several speakers at the same time.
Before stereo radio, speakers were often located in the middle of the dashboard through perforations pointed at the front windshield. When stereo systems became available, car audio speakers came to be located in doors and in the rear of the vehicle in parcel shelves. In modern cars, kick panel enclosures are used for high-end and competition stereo systems and allow for larger drivers and better driver placement.
To drive the speakers you got to have an amplifier. This gives power to the music you are listening. A good car audio speaker system must have an amplifier, which is its very important component. Be sure that the total handling capacity of the speaker which is connected to the amplifier is greater than the power amplifier.
