PREPARING FOR INSTALLATION
Map out the wiring paths from the speakers to the amplifier. We recommend 16-gauge wire for
runs up to 25 feet, and 14-gauge wire for longer runs. Be sure the speaker wire does not rest or
rub against any sharp or pointed objects.
The speakers should be mounted on a flat surface to form a good seal between the speaker
flange and the mounting surface.
When connecting more than two speakers per amplifier channel, you should use series/parallel
wiring. In all cases, make certain that the total impedance does not fall below the amplifier’s
rating. If you are not sure, contact your Snell Acoustics dealer.
You will Need:
1) A utility knife, an electric jigsaw, or other means of cutting a hole in the mounting surface.
2) A #2 Phillips screwdriver.
3) A wire cutter or stripper for preparing the speaker wires.
With the supplied hardware, the speaker can be installed in existing walls or ceilings from 1/2”
(12mm) to 1
1
/2” (38mm). For thinner walls, you will need to use spacers for the mounting legs
(contact your Snell dealer for this optional rubber part).
INSTALLATION
For convenient installation, the Snell AMC720, AMC760, AMC 800 and AMC 900
THX
use a dog-
leg mounting system (see illustrations below). This provides a quick and clean install. Further-
more, the dog-legs can be removed if a particular situation requires to speaker to be directly
attached to a stud.
Note: As an added security feature, the speaker tubs can be pre-mounted without the baffle,
drivers, and crossovers installed. This will allow you to protect the delicate speaker components
from debris if significant construction work is being done near the speaker installation location.
1) Make an appropriate size speaker mounting cutout in the wall material.
2) Run the wire from the amplifier to the cutout. Allow an extra foot of wire at the cutout.
Strip 1/2” (12mm) off the wire, and tightly twist the wire strands together.
3) Remove the speaker grille.
4) Insert the speaker wires into the spring
terminal binding posts.
Important: Typically, one side of the wire is
smooth. Connect this side to the – (black)
speaker terminal. The other side has a rib or
stripe. Connect this to the + (red) speaker
terminal. Connect wire at the amplifier in
the same way. Failure to do so will result in
degraded sound.
Warning! To prevent electrical shock, always
switch off the amplifier or receiver when
making connections to the speaker system.
