You wouldn't cut into any wires, you just tap into them. Look for tap connectors at any auto parts (autozone, pep boys) store, even walmart sells them.
As far as the wire colors, I'm not sure, but once I find a list I'll post it. The easiest way to find out is to look at the speaker itself. You'll see what the wire colors are.
