Probably already discussed, BUT I don't see it anywhere's so, I want to buy a KGXS20G+, and I want to keep it simple for power supply. The radio comes with a lighter socket plug, but there seems to be some confusion on if it will work properly in a vehicle. My Toyota Tacoma has a lighter socket with 12 volts 120 watts direct to battery as per Toyota service dept. I also have a color generator with a similar setup. Will these work, or do I need a dedicated power supply? Thanks one and all.
