PCI 45DC Back Can Installation
WARNING: To avoid potential damage to your loudspeaker, ensure that the power amplifi er is
switched OFF prior to connecting or disconnecting any cables.
WARNING: Make sure that there are no power lines, other cables, or plumbing such as water,
sewer, gas lines in the chosen location.
The procedure below describes the installation of the back can into a typical 2" x 8" joist ceiling
with 16" centers, with drywall/plasterboard already installed.
After the PCI 45DC back can is installed and wired, the paint mask can be added for painting
and finishing. The loudspeaker can be installed into the back can later .
Procedure
Follow the procedure steps below in the order in which they are presented. Read all the instructions
before starting.
1. Locate a suitable mounting position for the speaker, using a stud-fi nder. WARNING: Make sure
that there are no power lines, other cables, or plumbing such as water, sewer, gas lines in the
chosen cutout location. Also make sure that the location is far enough from ceiling joists so that
all the clamping mechanisms can operate without interference.
2. Carefully mark out a square in the desired location and carefully cutout a hole in the drywall/
plasterboard. Remove any dust and debris from the hole (Fig. 12).
3. Run the speaker wire from your amplifi er to this location, leaving enough slack to allow for the
connection (Fig. 13).
4. If the loudspeaker assembly is already fi tted to the back can (during shipping for example) then
remove it from the back can by undoing the screws holding it in place (Fig. 14).
5. Remove the block of shaped foam inside the back can. This is used to protect the speakers
during shipping.
6. A square sheet of acoustic foam is supplied with the packaging. Install this foam to the inside of
the back can. (Note that the foam is not shown in the illustrations below.)

Wiring the Back Can
WARNING: To avoid potential damage to your loudspeaker, ensure that the amplifier
is switched OFF prior to connecting or disconnecting any cables.
WARNING: Before switching the amplifier ON, double check that all connections are
secure and that the polarity is correct.
Note that the speaker wire connections are made to the two screw terminals on the
outside of the back can.
We recommend the use of insulated speaker wiring of between 12 and 18 AWG.
1. Pull out the ends of the speaker cables from the cutout aperture, and strip off
approximately 8 mm (¼ ") of the outer protective layer from each conductor.
2. With the help of an assistant, hold the back can up near the aperture.
3. The speaker cable may be wrapped around the bar near the screw terminals on the
back can (Fig. 15).
4. The positive wire from your amplifi er should connect to the positive terminal
of the back can. The negative wire from your amplifi er should connect to the
negative terminal of the back can. Secure both wires by tightening the two small
screws. Make sure that the polarity is correct and the wires are secure.
5. Make sure that the speaker cables are secured to the ceiling joists so they will not
move and rattle about during operation. Also make sure the cables are not near
any screws or sharp metal edges that may cut the insulation.
Installing the Back Can
1. With the back can wired correctly as shown above, connect a secondary safety
cable to the metal mounting loop on the rear of the back can. The other end of the
secondary safety cable should be secured to suitable strong mounting point in the
ceiling (Fig.16).
2. With the eight back can mounting clamps in the stowed (inward) position, press
the back can into the drywall aperture. Be careful not to pinch the speaker wires
or your fi ngers (Fig.17).
