Wireless iPod Speakers are quite amazing and can save you wiring and more.

Wireless iPod Speakers
We used to suggest EOS but do not anymore. There are many others to provide wireless speakers and/or functionality. Using wireless speakers is a huge time saver, you can simply plug in your iPod. Then place the other speakers anywhere in your home/business and that’s it. You now have music throughout, without any wires to install. There is also no static, if you have tried wireless speakers before you know that can be the biggest issue.
