The term “car audio” is an umbrella term describing the sound system fitted to an automobile. Somewhat different but quite similar is the “stock car audio system,” which refers to a system specified by the manufacturer when the car rolled off the assembly lines. At its extremes, the installation of custom car audio can involve anything from the upgrade of a radio to the radical full-blown customization of a vehicle around its audio equipment to include features such as car stereo CD changers.
A head unit usually consists of a combination of a radio, tape player, or CD/DVD player. Newer head units are now emphasizing on digital music support (MP3, WMA, and AAC formats) and USB, Bluetooth, and Wi-Fi connectivity.
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.
Stereophonic sound is commonly referred to as stereo and it is the reproduction of sound wherein two or more andependent audio channels are used to create the same effect as hearing natural sound heard from different directions, same as that heard in natural hearing. Car audio stereos usually employ 2-channel sound recording and sound reproduction using data for more than one speaker at the same time.
When car audio systems had only one speaker, it was placed in the middle of the dashbaord, with perforation through the front of the dashboard allowing the music to be heard. Now that stereo systems are standard, car audio speakers are placed in less standardized positions, such as in the doors and under the rear shelves. A higher end system should place speakers in kick panel enclosures, to allow the driver more comfort with better sound.
Amplifiers are used for driving the speakers. They provide the necessary music power that is measured out in watts. An amplifier is a really important part of a good car audio system. You should always be sure that the power handling capacity of the speakers that are connected to the amplifier / head unit is larger than the power of the amplifier or head unit itself.
Car audio is a sound system fitted in a car. The car manufacturer fits the basic system whereas the owner can fit and customized system of minor/major changes including car stereo CD changers installation. Head units refer to radio/tape/CD/DVD Player and with recent developments CD players are provided with WMA/MP3/AAC/USB/Bluetooth/Wi-Fi. CD Changer holds multiple CDs and facilitates continuous viewing. They can be External/Internal Cartridge or Carousel type. Car audio stereos use two channels to reproduce sounds with directional effect. The car audio speakers are positioned in doors/rear parcel shelves. A good car audio speaker system must have an amplifier and the speaker’s capacity should be higher than amplifier.
