One of the common mistakes car owners make in radio installation is not being focused.
You have to be careful when matching wire colors because you might not be able to use the car radio otherwise.
And by the time you realize your mistake, you’ll have already installed the new radio into the dashboard. It means taking it out again and checking each wire one by one.
So, to save yourself from this hassle, see the wiring diagram for your radio attentively before making any wire connection.
