The car audio system may not seem like it is an important feature in your vehicle, but spend a little time without one and you will soon see how important it really is.  The car stereo has the ability to make a long trip seem short and get you through all those traffic jams when your patience is wearing thin.  A car audio system is a complete unit that is comprised of a number of components.  Each of the components is important for the enjoyment of your music.  Here is a rundown of each of the components in a car audio system. 

The most important part of the system is called the head unit.  This is the part of the system that will actually play the music.  Most head units have an am/fm tuner, CD player and newer systems also include MP3 capabilities.  Some other head units will include a satellite radio, DVD player, LCD screen and even a connection for your Ipod. 

The next component is the preamp.  This is used to amplify weaker signals and adjust the sound on your system.  This part of your car audio system is where the volume, balance and tone is adjusted on your system.  It is here that you will make your subwoofers speakers thump and roll. 

The amplifier on your car audio system will boost the signals that are sent by the preamp.  This is what will make sure that your speakers are able to handle the power that is coming from your system.

Finally, the speakers are where the audio is emitted from your car audio system.  The speakers can be located in a number of places in your car.  Most of the time they are placed in the doors of the car and in the rear window area.  Subwoofers speakers are included on most modern high end cars today, but if you have an older car, you will have to add these to your system. 

Choosing the correct components for your car audio system will ensure that you are able to hear the music in the way that it was intended to be heard.  If you like rap or techno music, you should consider getting a good pair of subwoofers speakers to enhance the bass of the music.  Your musical taste will play a large part in the components that you choose for your car system. 

There have been a number of innovations in the car audio system that you will find available today.  Some systems include wi-fi, DVD players, LCD screens, and a number of other features that you may find useful in your car audio system. 

Shop around before you choose the components for your car audio system.  You can often find a good deal on an entire system that is complete with all the components included.  However, if you have some special requirements for your system, you may consider shopping for the components that you want included in your car system.  For example, if you would like more bass in your music, you might choose to install two subwoofers speakers in your car instead of just one.
