Color organ+opamps=?

Hello everyone, I was recently watching a video by Collin Cunningham when he made an LED color organ. It was cool, but could it be taken a step further? Instead of resistors and LED's, what would happen if that signal was used as an input to an array of opamps? There are 3 outputs in his video, one for bass, mids, and treble, so could those same outputs be used to power an amp with a subwoofer, midrange, and tweeter? It was just a thought, and has already been used to make surround sound equipment, but could I make my own? Thanks.
