Grounding multiple TV’s

I am getting ready to install 4 tv's in my 2004 Duramax. 2 6.5" in the visor, and 2 7" in the headrest. My question is how do I go about grounding all 4 of these tv's. Should I ground them as short as possible separately, or should I ground them all at the same point? Also, what is the best kind of video jacks to use on these tv's?

What is a Duramax? It is normal to ground components with the shortest length possible. In the case of a short, current will travel to the shortest path to ground. A fuse will help on each power wire, too. Commonly, all your video signal wires will be run in one cable. This will have the 2-CH Audio, 1 Video, Power and Ground. You could splice all the grounds together and solder the connection to one larger wire (12-14 Ga would work well), then properly terminate to ground. Video has optimal carry on a 75-Ohm cable. This is what you would need. Not sure about connection material, though. DXAV

Excellent. I figured it was a truck. DXAV Wussy posts like this one (mine) shouldn't really count, huh?
