All About New Car Stereo Technology

People were considered lucky when they used to have a radio in the dashboard and two speakers in the front doors. Thanks to the latest car stereo technology, car stereos now can compete with even home audio systems. Analog has long been transformed into digital format. Some of the latest car stereo technologies are surround sound, Dolby Pro-Logic, Digital Signal Processing, MP3 technology etc. Similar to the home stereo system, improvements in technology has resulted in improved sound performance and clarity.

The composition of a car stereo system is based on four basic components. These are amplifiers, speakers, head units and input devices like graphic equalizer, CD changer etc.

The head unit, as the name suggests, is the core of any stereo system. The head unit or radio is called the central processing equipment of the device. It controls all the functions of the application like turning the volume up and down, adding more bass etc. Every manual sound adjustment is made by the driver through this head unit or radio. Behind the dash of the head unit, there are dozens of wires connected to power, speakers, antennae, and so on.
