The RGB bars will be wired up in parrellel with each LED getting 3 resistors. So I don't think I would need the resistor in front of the pot, because there is resistors on the LEDs.. There will be 4 wires going into the Bar, with one red, one green, one blue, and a ground. With a pot on each of the RGB wires. If this does any good please respond or ask more questions of what you need to know, all I need is 3 potentiometers that can resist the flow of 12V DC.
Thanks
