Origin, development and history of the car stereo
Since the car was used, various appliances, custom fans use their cars. The commercial launch of the car stereo system installed in the form of radio from the 1930 Galvin Manufacturing Corporation.
Production was Galvin is owned and operated by Paul V. Galvin and his brother, Joseph E. Galvin. The Galvin brothers purchased a battery eliminator in 1928 and the first company product was a battery eliminator that allowedbattery-powered radio to work with standard household electrical current.
This was in 1930, was the Galvin Corporation, the first commercially successful car radio, Motorola model 5T71, which for $ 110-130 dollars, sold and can be installed in almost all cars popular.
The name was created by Motorola's founder Paul Galvin and Joe Galvin and his company started manufacturing car radios. prefix Motorola car was chosen because the initial focus wasAutomotive Electronics.
The development of the car stereo was then held in different parts of the world.

It was the beginning of the development of the car stereo.
The first car stereo systems, radio receivers used for the battery voltage is 6.3 volts when the strands to implement andcreated to provide the necessary high voltage with a vibrator step transformer stations. The receivers required more stages than the typical home receiver and sufficient profit to ensure that the AGC has been available to mask signal fading when the car was driven around. Shortly after, when the cars go to 12 volt batteries, the system uses the same where, instead of stove pipes used 12 volts.

search function allows users to adjust from one station to another with the touch of a button. After this followed the introduction of semiconductors. Allowed to change the output stage transistors in a semiconductor, which quickly led to the removal of the vibrator, and use of space charge tubes only12 volts needed for their plates.Thus, there was another advance in technology.
With the promotion of electronics with time allowed for new additions to the basic radio and Motorola. This result reel tape players used to provide equipment. Phillips, along with the introduction of the compact cassette players are also beginning to be used in a car.
In 1978, the amplifiers were introduced in the market, and they did not look back. Today, car stereo systemsA revolution with the launch of CD and DVD. Now the modern cars have radios, cassette players, CD and DVD players, and even MP3 or MP4. Although the video system was gripped by it.
