Car Stereo Cd Changers, Speakers And Amplifiers
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.
Most modern cars include at least a CD player/ CD recorder, and some have the option for car stereo CD changers, which hold multiple disks either in the head unit itself or in a separate unit usually located in a trunk or console. The main 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.
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.
The amplifiers are used to drive the speakers. These provide the necessary music power, which is measured in watts. An amplifier is a very important component of good car audio speakers system. One should always ensure that the total power handling capacity of the speakers connected to the amplifier or head unit is greater than the power of the amplifier or head unit.
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.
