Installing a stereo into the stereo dock of the Chevy Monte Carlo is a task that can be easily performed by a professional car audio technician. The stereo's wiring connections can be simply plugged into the related inputs on most aftermarket stereo decks. You can also install a new deck with little previous experience. Purchase the necessary tools and adapters for the job and you can have the new unit installed in less than an hour.
Open the hood of the Monte Carlo by pulling the hood release lever located on the driver's side of the Chevy, below the dashboard. Move to the engine compartment.
Disconnect the negative battery cable from the Monte Carlo's negative battery terminal. Use an adjustable wrench or pliers to loosen the bolt securing the cable to the lead post. Move the battery cable away from the battery until the stereo has been installed. Return to the inside of the vehicle.
Open the glove compartment. Remove the screw at the top left corner of the compartment with a Phillips-head screwdriver.
Pry the cover over the ignition with a trim pry removal tool.
Remove the two screws located on the dash panel under the steering column with a Phillips-head screwdriver. Remove the lower dash panel and set it aside.

Pull the factory stereo from the Monte Carlo's dock. Disconnect the stereo wiring connectors from the back of the stock radio. Unplug the antenna cable from the back of the unit.

Plug the wiring harness adapter lead connectors into the outlets on the right side of the new stereo. Plug the antenna adapter lead into the outlet on the left side of the new aftermarket unit.
