You'll have to run new wires for the DVD player. The stock wiring is built to handle just one unit, if you have more than that, there's the risk of frying the whole electrical system-not pretty.
You could run new wires directly to the battery or even the main fuse panel in this case for the dvd player. Don't forget an inline fuse somewhere in the constant battery line. Then ground it to the nearest bare metal (usually the seat bolts work well).
