matt is correct, you'll have to do the set-up manually. If I'm not mistaken, the RB-991 is a stereo (2-channel) amp but you're looking to hook up four speakers. You could connect the speakers in parallel to the amp, as it can handle a 4 ohm load, and as long as you don't crank it up the amp may be able to handle it. Otherwise, you may want another stereo amp or a single multi-channel amp.
