Disconnect the Battery

Uninstall the Old Car Stereo System

Here are the steps to uninstall the old car stereo system from its frame:

  • Remove the cover of the car stereo. It is the part where the button was placed. Some car stereos have a pop-off type cover, which you can remove easily by applying pressure. However, if you have a car stereo system that uses a bolt, make sure to remove the bolt first.
  • Remove the protection collar, which is the frame that goes around the cover, and protect its edge.
  • Use the release key to unlock the whole car audio system from the audio system bracket. The release key comes with the new car stereo system you bought or in the car maintenance kit you have.
  • Remove the old car stereo system by pulling it off the bracket. You can use pliers to pull it out if you have difficulty doing it with your hand.
  • Please, pull the car stereo gently, because all cables are still connected on the back of its body.
  • Once you pull all the car stereo bodies from the socket, remove all the cables, starting from the antenna cable (the black and thick cable) and the speaker and power connector (multi-color cables).

  • Connect those cables to the new car stereo system. Make sure you connect them firmly, so it can work without any problem.

Things to Remember Before Installing New Car Stereo

Thus, you might want to remove some parts of the dashboard to remove the bracket and install a new one that fits with the new car stereo system.

Also, if you are not confident to do all the steps yourself, you can always ask for help from experts. That will help you to save more time. Moreover, it reduces the risk of mistakes that can ruin your car audio system.


In conclusion, changing your old car stereo is doable without help from the expert. Follow our guide on How to Install an Aftermarket Car Stereo System to do it smoothly. So, try it now
