I have very little skill or knowledge in this area, so please be patient, and don't assume I will understand the terms you use. I'd like to set up speakers in other rooms, to listen to my computer music files. I have a pair of inexpensive Cambridge Soundworks GCS300 speakers that came with my computer. I salvaged a couple of speakers from a discarded home entertainment system in the trash, and planned to use old speaker wire to splice them into one of the lines from the computer speakers. I've tested these old trash speakers, and I know for a fact that they do work. I was first surprised when I cut one of the wires, to see that it wasn't just bare copper wire under the outer insulation. There was also a second tube of plastic inside, surrounded by the copper....it appears to also be a copper line. I'm figuring that if I also strip THAT, then the system won't work...I'm guessing this interior portion has to be kept insulated from the other wires. Spliced all tothether, and nothing is working. Any advice in repairing the wire to the one now-useless computer speaker would be appreciated. I'm guessing that I'm doing this wrong? I'm guessing that what I need to do is get a cable that will hook the audio output of the computer to my stereo, and instead of splicing the computer speakers, splice into the stereo speakers. But I don't know what this cable would be called, or where to get one. Thanks for looking.
