Can an iPhone 4s be connected to more than one wireless stereo at once?

I just bought an iHome stereo that connects to the iPhone wirelessly. I really like it, but I don't think it's loud enough. Is it possible to connect my iPhone 4s to more than one wireless iHome at once?

No. Then it would lose connectivity. I mean you can give it a try. I know I haven't. But it's best and more efficient one at a time. Why do you need to connect to 2? If one isn't loud enough, then don't use it. I believe I'm right. You can only connect to one at a time.
