I'm not really sure what you mean about in parallel or in series. There's only one resistor endpoint, the speaker. Then there are 3 speakers, each in a different room. There are two black and two red wires going into each speaker. I don't really understand why one red and one black doesn't suffice, but anyway the two red ones are next two each other and the two black ones are next to each other at the two points where they connect to the speaker. These four wires are connected to two red and two black wires coming out of the wall. I just labelled the eight wires so I could match them up again later and undid the four nuts, leaving one nut on each end of the live wires coming out of the wall. Then I just shoved the speaker assembly back in place, and you can't tell from the outside that it's disconnected. I hope that was clear? I didn't short any wires together, I put the wire nut back on a live end to be paranoid. One speaker is apparently wired like this: RWin - Rnut - RSin - speaker - RSout - Rnut - RWout BWin - Bnut - BSin - speaker - BSout - Bnut - BWout where R = red, B = black, W = wall, S = speaker. But I don't think you can tell about series vs. parallel from that relative to the other speakers. Except this: it's perhaps in parallel since there are two red and two black; in series you would only need one red and one black, right?
