Having a good car stereo provides you the best sound for your ears while you are driving. Whether you listen to the radio in the morning on your way to work, or you enjoy a fast electronic music, car stereo is a necessity for every person who spend a lot of time in the car because it makes the travelling more pleasant. Some automobiles have build in car stereo from the manufacturer itself that can be quite good. But for the passionate sound addicts these car stereos are never good enough, and they always upgrade the existing one or completely change the car stereo with a new one or very often even with a custom made car stereo.
Car stereos usually have three components, the head component where all control buttons, the radio and CD player are placed, and speakers which are usually built in the doors on the car to save space. Custom made car stereos apart from these two parts usually have subwoofers which are specifically loud speakers which the sound addicts like to put in their cars. Custom made or modern car stereos except the head unit, the speakers and the subwoofer, also have build in an amplifier, capacitors and duping on deadening materials for reducing the excess vibration of the panels in the car in response to loud subwoofer bass tones.
The head unit is the primary control, multi-purpose device in a car stereo.
The most usual components are a tuner with AM and FM bands as well as a small amplifier for bringing an audio signal to speakers. Other potential parts that can be included are diverse media devices, like tape player in older cars CD and DVD player, USB ports, even a portable hard disk drive might be built in. Many primary control devices in a car stereo also introduce a DSP and equalization components, as well as an interface for controlling another device that is build in the car like a parking camera, navigation system, odometer, etc.
Car stereo speakers are same like other loudspeaker with the same key components specialized for use in mobile settings. In most modern systems, speakers are based on certain parts that are common for all cars. These common places are the front and the rear deck, than the kick panel or the doors. The subwoofers are commonly based under the seats or in the trunk. Each position has its own assets and weaknesses in the quality of sound, and the viewpoint of the manufacturer itself.
Extremely loud car stereo sound systems in some countries and cities are restricted or even completely banned. The loud sound decibels can be dangerous and prevent the driver from being concentrated on the road which might lead to accidents.
