1. Binding Posts
The subwoofer has one pair of binding posts for connection with speaker wire to the
output posts of the Sunfire HRSIW8AMP or Proficient M3 amplifier.
Always use high quality connections and speaker wires, and make sure there are no
loose fittings or stray wire strands. The spring connections accept bare wire or pins.
Connect the positive speaker-level output of the amplifier to the positive (red) input
of the subwoofer. Connect the negative speaker-level output of the amplifier to the
negative (black) input of the subwoofer.
Make sure that the positive and negative connections do not touch, or this may damage
your power amplifier.
2. Speaker Wire Channel
To ease installation, the speaker wiring are passed through these channels to the
binding posts. This is recommended as the channel will support the weight of the
speaker cable, so it does not pull on the binding posts.
3. Clamps
Once the subwoofer is pressed into an opening in the sheetrock, screws on the front
panel are turned to pull the clamps out and down to press against the sheetrock, and
secure the subwoofer in place.
