Battery Powered Speakers

The louder the better but you have to balance the size of the speakers vs what you can realistically place inside the suit. I searched for the loudest battery powered speakers that could run off an MP3 player I could find. In 2005 these were the best I could do on-the-cheap. I dismantled them and placed one speaker in the left breast and one in the right. To make that happen I had to extend the wires which was easy with a soldering gun and some patience.
