How to Install a Stereo in a Pontiac Grand Prix

by Editorial Team

The sporty Pontiac Grand Prix has been around for generations and many of the older cars are ready for a new stereo. Installing a new stereo in the Pontiac Grand Prix allows you to add options like subwoofers and iPod docks. Swapping out the stereo in the Grand Prix requires removal of several large dash panels and some basic tools. These instructions cover the model years 1992 to 2000.

Step 1

Open the hood and disconnect the negative power cable from the battery. Place it safely where it won't come in contact with any metal parts.

Step 2

Locate and remove the two screws that hold the lower trim under the steering wheel. Drop the trim to the floor and set it aside. Find the two screws that hold the instrument panel cover and remove them. Pull the instrument panel forward and disconnect the gauge wire. The cluster and trim surrounding the stereo will now pull out.

Step 3

Remove the two screws that hold the head unit in place, one on each side. Pull the stereo out of the dash and disconnect the wires from the back of the radio.

Step 4

Connect the wiring harness adaptor to the original harness and slide the GM antenna adaptor over the original wire. Secure the new stereo into the GM radio mounting kit.

Step 5

Plug the wiring harness adaptor and antenna wire into the back of the new head unit. Slide the entire assembly into the Pontiac Grand Prix dash, taking care not to pinch the wires.

Step 6

Reconnect the negative battery cable and turn the radio on. Test the speakers and stereo controls to endure they work properly. Secure the stereo into the dash with the two original screws, connect the gauge wires and replace all of the trim.
