I got my basement built recently and i got them to do some inside the wall wiring so i can set up a home theater. I bought a receiver now and i want to put my speakers in. The problem i'm facing is how to tell the difference between a red and a black wire(positive and negative). If you need more information please ask i will answer your questions so you can help me out. Are there any tricks to tell which side is positive and which is negative.

Touch the wires to a 1.5v battery, so that you can see the cones move outward. If they move inward reverse the wires so that they do move outward. The wire touching the + pole of the battery is positive.
