Anyone know how to connect a playstation 2 to a car TV??

May be...

we have a tv in our car but obviously the playstation has to have power.

Is there a cable that goes connected to the car or something??

If so, where can I buy it? Walmart?

You have to find in your car the spot where the cables go (just like the back of your TV, red, white, and yellow ports) after you plug it in you have to have a power converter (you can buy them a Wal-Mart, Target, etc.) it looks like a car charger but it has an outlet just like the one on your wall at your home. After that you turn it on play till your hands fall off! lol

Yea, for our van w/ a tv, we had to buy this adapter thing for the power, prolly just have to ask about it at best buy where we got ours, cuz there is multiple ones that give you an outlet to plug it in, and the audio/video cord i believe should just be somwhere on the car if the car came with the tv.

You can use a simple power inverter like this... http://www.walmart.com/catalog/product.d...

yah theres this thing that looks like a car charger but it has the power outlet instead of a wire and yea i saw it at walmart

no idea!
