1. Firstly, remove the cardboard pad from inside the supplied template to mark the position for the mounting hole at the selected location.

2. Before cutting ceiling speaker holes, it is suggested that the area is tested for clearance by making an L-shaped probe from strong wire (see
illustration below), drilling a small hole in the target area, inserting the probe and slowly turning. Any obstructions will be immediately obvious, and
the target area can be moved to a more suitable position.

3. Cut the mounting hole with a drywall, or keyhole saw. Be sure the mounting surface is between 10 and 30mm (0.39 - 1.18”) thick, and that there is
at least 80mm(3.15”) of clearance behind the mounting surface.

4. Use 16 gauge minimum speaker cable to connect between your amplifier and your speakers. Ensure that speaker cables are routed away from any
electrical cables and that any amplifiers/sources are switched off during installation.

5. Use a wire stripper to strip 10mm of insulation from the end of each speaker cable and twist the strands together.

6. When connecting speakers pay extra attention to polarity ensuring that red (+) terminals on your amplifier are connected to the red (+) terminals
on your speakers, and that the black (-) terminals on your amplifier are connected to the black (-) terminals on your speakers.
