A car stereo is a sound system that is fixed inside an automobile. Nowadays we do not have to buy and install a car stereo; most of the time it is pre-built inside a car. It includes a number of equipment like amplifiers, speakers, and CD or cassette player. The features include specially designed in built items to go with the design and components of the car.

The demand for car stereos is rising so much that manufacturers of home audio system are investing in this field. This resulted in tough competition that compelled the makers to update the technology and provide similar features at a much cheaper rate.

Before buying the audio system, one should consider some points. It is important to see whether the car stereo fits in the car or not. Car stereos are bought for great sounds, so checking the sound quality before buying is also a good idea.

People used to put their battery operated music system inside the car for the listening experience; however, it was before the invention of car stereo. The drawback was the inability to cope with the high temperature and the shake inside the car. The first car stereo speaker that came to the market was a radio fitted in the dashboard with two speakers in the front door.

Motorola was the first to bring this kind of car stereo to market. The battery of the old car stereo was not of superior quality and could not be played for longer hours. It could only play audiocassettes. Moreover, the sound quality was not up to the mark. The longevity of this old car stereo was poor too. Compared to new car stereo the old car stereo was quite big in size.

Other than the looks of the car stereo, the products are always valued for sound quality. The new car stereo has a DVD player and pop up display LCD screens. The LCD screens can be either slide out or folded, though that depends on the head unit. Nowadays, new car stereos can fit in traffic signal messages and has a memory card with huge space. Some of the new car stereos include MP3 players, CD system, etc.

An MP3 car stereo is a kind of stereo that can play audio CDs, MP3 files, etc. and that too for longer hours. One of the distinguishing features of this stereo is programmable track memory. The memory also comes with digital anti skip facility and digital standard headphones. In addition, they are endowed with AM/FM tuners where one can store FM and AM stations.

Loud car stereos are quite a craze among the young generation and can play music above 140 decibels. However, this kind of stereos can cause hearing problems. In fact, loud music inside the car can make one unaware of the surroundings that may cause severe accidents.

CD car stereos have become an essential car necessity. This new kind of car stereo is provided with radio. It is helpful in many ways because it allows the user to access or go through the latest updated news, information regarding travel, etc. They can also play MP3.

Presently, car stereos are not only entertainment equipment but, to some extent, they have become a status symbol also.
