With all due respect, you should not have cut the wires. I think wal-mart has the wiring harnesses for like $7. I know that doesn't help you now, but I just wanted to mention it for anyone else that reads this thread.
As for your situation, you should be able to pull up the wire colors on google, or you could get them from a local stereo shop. (they might charge you for the info) But remember, if you wire the + & - wrong, the speakers will be out of phase and you'll lose all of your bass.
