selecting the proper a/v eguip

I have 4headrest monitors, a ps2, backup camera and a jvc in dash dvd player/ screen. I'm trying to figure out what size switcher,power inverter, video amplifier and connectors I will need so please help me out. BTW, the connection for reverse is hooked up for the backup camera. I pretty decent I just wanna make sure i'm buying the right stuff haven't done an install of this magnitude before. Thank you!

Well you would need a video signal booster capable of supplying at least four screens, the inverter's only use here would be that of powering the playstation, so once it's capable of supplying a couple hundred watts you should be good! You would need rca cables for all the screens and for the reverse camera!commit your way to jehovah and he will act in your behalf. psalms 37:5
