Yes. The board doesn't power all three (R, G, and B) at the same time - only one at a time. They're separated by the 3-position slider switch - so if you still want light on each sound bank, they would have to be connected. You won't fry the board, but you won't get a lot of power out of the LED.
As for the neg, I pulled the wires off mine a long time ago - but it's labled "GND" for ground.
just a thought... would this be considered multiple sound banks?
