Hey, found this site on Google, was wondering whether anyone could help me. Basically, I'm trying (unsuccessfully) to wire up some old headphone wire to a pair of stereo speakers, but I don't know how to do it properly! The wires that I stripped back from the headphones are red and copper, and green and copper, but the two strips of wire from stereo speaker are just silver. One strip is coated with white plastic casing, the other is black. Which wires should I connect up to which headphone wire? Hope someone understands this question and can answer it for me! Thanks very much, Kerry

Use the copper as the + and the red and green as the - legs.
" ... but the two strips of wire from stereo speaker are just silver."
The speaker wire probably has some form of identification, look for a ridge or a white stripe on the insulation of one leg of the cable. Use that leg as your + feed. If you can find no identification, use a small voltage battery and touch the two legs of the cable to the + and - terminals of the battery. The connection that makes the woofer move forward is the right orientation for + and - legs.
I have a similar question. I'm trying to wire my sister's pet hamster directly to the mains. Which is the best place to put the crocodile clips... On the ends of it's ears, or up it's ar$e?
