EMICS 2 Questions

I recently purchased the EMIC 2 but am having problems grasping a few things. When I read the tech stuff I didn't see any answers and what I found on the web was basically useless.
First - it needs a wall wort to power it, 5V if memory serves. However I do not find any information on the size of the barrel jack, or if a specific amperage is needed. If the amps doesn't matter than finding a 5V power source is easy, however to many amps will melt a board, wire, component, or worse, start a fire. Once the magic smoke is out, you can't put it back.
Second - how do you power a speaker? Little buzzer speakers are basically pointless, but I can't find anything about how to drive a larger speaker. It wouldn't be hard to run something to a transistor and power larger speakers, but then how does the line signal make it to the speakers?
Third - What about hooking it to a Propeller? How do you do that? Is there any reason why I can't just have a pin on the Prop activate the EMIC?

There is no power barrel jack on that product. The jack is for headphones or a powered speaker. I use the emic2 with my Activity Board and use the 5v header on that board to power the EMIC.
Here is a post where I explain how I used the emic 2 with my Activity Board programmed in C.

In this post I use Blockly to program it. https://forums.parallax.com/discussion/166190/blockly-emic-2-text-to-speech-demo
Hope this helps

So can I use a external speaker and pull the signal from the EMICS?
Second can the tonal qualities to be changed to improve vocalization?
This is nothing like the speech work I did before so its like learning all over again.
