You can use anything, even pretty thin wire. Generally 22 ga is a happy middle ground for that sort of thing. It doesn't really matter if you use solid core or stranded, but you'll find the stranded easier to work with.. It's more flexible.

Looks like it can run on 3.6v up to 12v

Hi guys, I'm the fella chookaboom is referring to. I've been working on an amp kit for some time, trying to make it as flexible as possible, while having it be as easy to install and use as possible. I think I've come up with a pretty good solution, but will let other weigh in on that. Unfortunately, it's not as easy as TKinTraining suggests. The amp has to be powerful to drive the speakers, and you can't just connect a simple electret mic to a small amp.. it just wont' work without a pre-amp. I do use the amps he refers to in other projects, but they won't work alone in this sort of implementation. I have a thread in the ongoing sales forum.
