It is a must for cars to have car stereo systems we are told. Not for the entertainment value but because it is one of the pieces of electronics that is considered to be a standard part of a modern vehicle. Every car usually comes with stock audio systems, but they are mostly models that offer mediocre sound quality and have features that are quite limited.
You might get used to inferior quality, but most likely you and your passengers would enjoy journeys more with higher quality musical entertainment. You don't have to stick with the original automobile sound system, you could choose to replace it with something better that could add value and appeal to your car's interior. A good idea, but before you go out and buy a new car stereo system you need to know about the basics first, and hopefully you'll understand how they work properly.
How Car Stereo Systems work
As soon as you turn your car's audio on you will hear a sound that comes from the head unit. The head unit is the part that controls the frequency of the radio, controls the CD or MP3 player that you have in it, as well as controlling the balance and equalization. The signal from the head unit is then boosted or amplified by the audio amplifier and finally it is sent to the speakers. The signal that travels from the head unit to the speakers tells whether the car stereo systems have a bad sound or a great sound. If you're radio sounds bad, it's not really the fault of your speakers; it's your amplifier which is not working properly. Stock stereos have their amps at the back of your radio. But if you buy high quality car audio systems, the amp is located elsewhere and is just connected to your unit via a cable.
If this is your first time looking for a car music system I would say that the first characteristic that you need to consider is the power of the system. The amplifier power is measured by wattage per channel. So when you're buying one, you should be particular that you don't pick those advertised with all the wattage added together. A system with 50 watts total actually has two channels, meaning 25 watts for each channel.
Another thing that you could look for is its compatibility with modern devices
