If you take your car on long family road trips, having headrest DVD players for backseat movie viewing for the kids will make those trips easier. If your vehicle didn't have these DVD players originally installed, you can install aftermarket models into the headrests. This will take some cutting up of your headrests but can still be easier to install that an overhead player by comparison.
Remove the headrests from the front seats and take off their upholstery covers. Draw the front outlines of the DVD player holding frames on the back sides of the foam cushioning with a permanent marker.
Cut out the holes drawn on the headrests. Using a razor knife, dig and hollow out the hole until it is deep enough for the frames to fit into. Use the frames themselves as a guide to gauge the needed depth.
Insert the frames into their holes, gluing them into place with contact cement. Insert them while the cement is still wet, wait for the cement to set and then push them all the way into their holes.
Poke another hole into each headrest where the hole in the bottom of each frame is. The hole can be made with the tip of a large Phillips screwdriver.
Return the upholstery covers onto the headrests. Cut the upholstery away where it covers the frames, slicing an "X" down the middle and then cutting away each flap you created. You can glue the edges of the remaining upholstery to the frame with more contact cement to hold it in place.
Fit each DVD player screen into its frame once you know all the contact cement has dried and hardened. Run the wires through the holes in the bottom and attach the headrests back onto the car seats. Connect each screen to the player's central console with audio/video cables and store the console somewhere safe, like under a seat.
Connect the DVD player wires to the vehicles electrical system. If the system needs to be wired directly, the cable should include three wires. Usually, the red wire connects to the car starter, the yellow wire connects to a constant 12-volt source like the battery and the black wire is mounted to a metal ground.
