Installing a TV set with a DVD player in a car has become common for many people. The next level is installing a game system. There isn't a standard method for installing one, but it is possible. Once your car has a TV inside it, you can load your PlayStation or Wii into your car for game playing on the go. The most important things are finding a secure location for the game system in the car and a way to connect its power supply to the electrical system.
Install a TV set in the car if it doesn't have one. The TV needs input ports that will work with your game console; most use RCA composite plugs. Most car TVs go into a seat headrest; cut a hole in back of the headrest and fit the TV frame within it.
Mount the game console in a secure place. If there is enough clearance, under the passenger seat is good. You can also mount it on the dashboard if it's not in the driver's sight or in the way of the airbags. Adhesive Velcro strips will hold it in place. If nowhere else, try storing it in the glove compartment.
Connect the console to the TV set using RCA cables. If the TV is within a seat headrest, route the cables up through the seat upholstery. This works best if the console is under the seat. If it's in the front, route a long enough cable underneath the seat and up through the upholstery.
Connect the console's power adaptor to the car's electrical system with a DC inverter. Place the inverter within a corner of the passenger floorboard and plug it into a cigarette adaptor. Run the console's power cord from underneath the seat (or along the edge of the dashboard) and plug it into the inverter.
Store your system's games and controllers in a secure container. A car organiser from an auto supply store will work and usually mounts onto any floorboard with Velcro strips.
Keep an eye on the inverter, as it may require up to 400 watts for the TV and console. Many inverters will warn you if the car battery is getting low.
