Thanks Reelsore.
A few years back I picked up a homemade prop that consist of a small black wooden box with a couple small 4" car speakers on the sides, (I know car audio usually is a 12v set-up), and then this cable coming from inside the box.
In order for me to get inside to look, I would need to basically tear the thing up, and wanted to avoid trashing it. So after googling what was printed on the cover, I didn't have any luck find out more about this bulk cable.
So what puzzles me is that I figured to run two small car speakers, it probably would need to be hooked up to a small lawnmower battery, but after seeing the 3 wires, it looks like the wires that are found inside any regular extension cord.
My gut told me that if I added a 3 prong plug and plugged it it, I probably would either electrocute myself or at least get the famous poof of blue smoke.
Does that help out?
Thanks again,
PB
