Would would need an Inverter, kinda looks like an amp. This will allow you to convert your cars dc power into household ac current. Then you will need to find a suitable place to put it. I know that your car is kinda small so I would recommend the trunk. Then nyou would need a place to view it. A nice place might be sunvisor tvs. You may find this easiest to accomplish if you let a shop install thetvs but the game system should be no problem.
good luck
