Hooking up multiple car tv's but they keep going out

[george1975]

I hooked up 9 car tv's and when I turn them on they play about 5 minutes then 1 or 2 would cut off. When I cut my subwoofers on more tv's cut off and the others ones picture would jump. What do I need to do to make them stay on. Please help
