A standard car stereo (also called a head unit) usually includes an auto-reverse tape deck, a cd player and sometimes the optional changer – a device which automatically changes the cd in play. On newer car models, the car stereo can also play mp3s and other digital audo file types like WMA and AAC, whether on a cd or a memory device which can be hooked up to the head unit.

The car stereo head unit is connected to several speakers. Older car models usually just had one speaker mounted underneath the dashboard, pointing through perforations towards the front windshield. The standard for car stereo nowadays is a pair of “tweeters” (used to bring out high treble) on the driver side/front passenger side dashboard, a pair of normal “mid” speakers on both doors, sometimes even the backseat passeger doors if it’s a large car and larger speakers capable of bringing out low ends at the back protion of the backseats.

Your car stereo is probably ok as it is, as car manufacturers ensure that the audio products that come with their cars can handle most dirver’s listening demands. But if you think that what you have isn’t enough, you can always CUSTOMIZE.
