Remember that wire I was talking about?

So, I dunno. This is making me nervous.

The wire that I touched with another wire. Well. There were two power wires coming from the car for power. There were two wires coming from the stereo for power. I tried each with each. They were both supposed to be power wires. So, I got genius and I decided to connect the two power wires from the stereo to the one power wire from the car.

And it worked.

Should I be concerned that I connected two power wires to one? Suddenly I am.
