terminals of the amplifier. Always check to ensure polarity is correct:
L(left) to L, R(right) to R, “+” to “+”, and “-” to “-”.

Installation
The loudspeaker can be installed both on the ceiling and on a vertical
surface. It is strongly recommended that the mounting surface is flat (not
curved).
Ensure that the mounting surface is free from obstructions, pipes or studs,
either in front and behind the surface.
The cable runs and cable pipes shall be set according to the loudspeaker
system configuration. The cables must be of adequate quality, suitable for the
installation’s environmental conditions and with proper copper section to
minimize power loss.
- Remove the grill from the loudspeaker and keep it in a safe place.
- Position the cutout template and mark the surface accordingly.
- Drill a pilot hole, then cut all of the way around the circular outline with a cutting saw.
- Pull the speaker wire out of the hole and connect it to the loudspeaker.
- Insert the loudspeaker into the hole and tighten all the clamp screws with a Phillips #1 screwdriver.
- Reposition the grill on the loudspeaker.
