DIY stereo stim - switching from transformer output to speakers?

[canonman]

I am hoping someone can help me out here, I'm wondering how I can switch between stero speaker output and the transformer out puts. I think I'll need some kind of changover switch but havent got a clue which type to buy or how to wire it up. Because there are 4 wires coming from the amp does this mean I need a 4 way switch?

The reason for this is I would like to use a pair of old computer speakers and mount the stim amp and transformers into one of the boxes and use a switch to change them between normal speakers and stim output.

I'm not sure if this can be done or not - help please!
Thanks!
