Most cars have a stock audio system installed on the assembly line, but they may be lacking in appreciable features. You can install an aftermarket audio system that plays the formats you want while offering you more options for adjusting the sound quality to your tastes. Professionals can install an audio system for you, but if you know what you're doing, you can perform the operation yourself.
Instructions
1. Locate the negative terminal of your car battery, and disconnect it. Never attempt to install an audio system in your car when electricity is still flowing--it's extremely dangerous.
2. Unscrew the dashboard cover with a screwdriver and pull it free of the surrounding car body. This should expose the old stereo system and allow you to work on it freely.
3. Disconnect the old stereo system from the frame and gently pull it forward. Look carefully at the wires connecting it to the electrical system and note which one goes where. You can use a pencil and paper to write it down if necessary.
4. Uncouple the wires one by one and remove the old stereo from the car.
5. Install the wiring harness for the audio system. This will allow you to connect all of the wires very easily. A few aftermarket stereos don't include a wiring harness, in which case you will need to connect the wires one by one, according to the instruction manual (this is the moment where marking the connections on the old audio system comes in handy).
6. Slide the new audio system into place, but leave it loose and unsecured. Check that everything is functioning before you finish installing it.
7. Reconnect the car battery and perform another check on the audio system. Make sure everything is functioning as it should, and that you are happy with the quality of the sound.
8. Screw the audio receiver into place and reattach the dashboard to the car. In some circumstances, you may need to increase the size of the hole in the dashboard to fit the new receiver, which you can do by measuring the needed space and cutting with a hacksaw or similar cutting tool.
