13. Press down on the spring loaded terminals to open the holes at the top. Observing the correct polarity, (, wire to , terminal and . wire to . terminal) insert the twisted wires into the relevant open holes (see figure 10) and release the springs to secure. Push any loose wire through the plate on the wall mount assembly and back into the wall.

CDo not connect the speaker terminals to one channel in parallel (together) with those of the other channel.
