I started having more and more issues. It was all centered around that 12V - 5V step down converter. DO NOT USE IT IN YOUR INSTALL! I have now removed it. If you battery changes in voltage, it goes crazyyyyyyyyyyy. Ive decided to just by individual 5V 2a adapters. Also I am going to go with a dual relay for controlling the screens. When I would turn one on, then the other, they both shut off. So I must have done something wrong with the diodes, so to save hassle, I am adding the dual relay. Also its not my amp that has the channel acting up.... Its actually the soundcard. I think it may be the PCI to PCIe bridge. I may have to get the PCIe version of the card. It just sucks though because I bought all the cables for it. The screen that had the brown tint now works. I think its the KVMP switch and the 12v to 5v converter.
