Some of the important things you will require is a new stereo, some tools such as screwdriver and a manual of how to remove your car’s dash panel.

2. Removing the old stereo

Before you install a new audio system into your car, you need to remove the old system. In order to do this you need to first disconnect the negative (ground) wire from the battery of the car. After disconnecting the wire, you need to remove the dash panel of the car so that you can access the old stereo system. After opening the dash panel you will find many wires attached individually.

3. Connecting the wires

After finding the bunch of wires you need to unplug them one at a time so that you do not confuse among them. After disconnecting all the wires you need to connect each wire yourself. You need to connect the positive wire from each speaker to the positive connecter which is on the back of the stereo first. After connecting the positive connector you can connect the negative connector on the back of the stereo.

After you have connected the positive and negative connectors you need to connect the ground wire of the stereo to a screw or bolt near where the radio is mounted in the dash. Ensure that the ground wire is attached to the metal.

4. Putting in the car stereo

After connecting the wires properly on the back of the new stereo, you need to slide your new stereo into the mounting bracket. If you have not received the mounting bracket with the new stereo system, then you have to use the old one to do so. There will be one lone wire left from the old stereo. This is the antenna. Plug that wire into the new audio system.

Now you need to slide the stereo system into the correct slot in the dash. Screw it only after testing the stereo.
