Removing the stereo from your car is normally a job reserved for professionals, but in some vehicles, the procedure is simple enough to complete at home, regardless of your automotive expertise. The 2005 Nissan Altima is an example of a vehicle with a fairly straightforward stereo removal process. A simple dash layout makes removing the factory stereo a 10 to 15 minute job. If your Altima has an aftermarket stereo, however, the removal procedure may be quite different.
Open your Nissan Altima's hood. Disconnect the black cable from the car's battery with a pair of pliers or a wrench.
Grip the rectangular trim panel under the radio firmly. This panel is around the air-conditioning knobs. Pull the panel firmly to remove it.
Remove the four screws behind the panel with a Phillips head screwdriver. The bottom two screws are for the knobs; the upper two screws are the lower stereo screws.
Grip the panel above the knobs around the radio on the lower edge of the stereo panel. The panel also extends above the air vents. With the knob panel removed, you'll be able to get a good grip on the lower edge. Pull it firmly to remove it.
Remove the four screws behind the panel you removed to detach the stereo. Pull the stereo forward and unplug the two connectors from the back.
