Great one!Read the owner’s manual carefully. Usually, you can get a good idea about the specific quirks of the model you’ve chosen, how it works, and how to install it.
Now collect your tools. You will likely need wire cutters and wire strippers, a screwdriver (usually Phillips head), and some electrical tape. Other tools and materials are often included with your unit.
Unhook the negative or black cable from your car’s battery. You do not want to get shocked, so by doing this you take the power out of your car’s electrical system.
Remove the dashboard and your old unit. This can usually be done with just the screwdriver, but when you are having problems consult the owner’s manual for the car or unit you are removing.
Check to see if the wires go into the old unit one by one or through a wiring harness. When it is a wiring harness, you can use another harness for your new unit and simply connect them all in one shot.
Connect each wire for each speaker (each should have a positive and negative) one by one. Connect the ground to a metal connection on the back of your new unit.
Connect the power wires to your new CD player. They are both red, and your manual should indicate where they are connected to the back of your CD player.
