Don't do that, you'll fry those speakers. When you bridge speakers (or subwoofers) you half the impedence (ohms) going to the amp. So bridging two 8ohms would give a 4ohm load, bridging 4ohms would give you a 2ohm load and so on. Anyways, sense your amp gives out 1100RMS x1 @ 4ohms, that means when you hook up a 4ohm load, you will be giving out 1100RMS, or 550RMS to each speaker. 550RMS will fry a 200RMS speaker in no time. You need more powerful speakers or a less powerful amp. As far as bridging, it will not hurt the amp at all, just the speakers. That is with the speakers you have. You don't say at what ohm level your amp is. Is you connect a lower ohm load than your amp is stable, you will fry your amp.
