5. If you have not already done so, run the speaker

wires to the source, or local room volume control.

6. Locate the speaker wires and strip 3/8" of insulation

from the ends. The stripped ends can be directly

inserted into the spring-loaded terminals on the

speakers once the terminal tabs are depressed.

Note:

It is important to maintain the polarity of the

speaker wiring between all of the speakers in the

system. Speaker cable usually has some means of

identifying the two conductors, either by color, a

molded in stripe, or markings on the jacket.

Familiarize yourself with the method used for your

cable, and be consistent with all the connections

within the system. On the MC300IW loudspeakers,

the Red terminal is used for “+”, and the Black ter-

minal is used for “-”.

7. Locate the speaker in the cutout. Using a

#1 Phillips screwdriver, or #1 Philips bit in an elec-

tric screw gun, tighten the six Phillips screws that

are along each edge of the speaker. The x-swing

arms will extend and grip the rear of the mounting

surface. Be careful to not over-tighten, only moder-

ate force is necessary to secure the MC300IW in-

wall speaker to the mounting surface.

Note:

A smooth, flat surface is desired for the most

secure installation and best air seal. If you are

mounting the MC300IW in-wall to a rough, uneven

surface such as stucco or brick laminate, use a

strip of foam gasket tape, or a strip of bead caulk,

along the back surface of the speaker’s mounting

flange. This will provide a good air seal and prevent

a loss of bass response. No gasket is needed on

smooth surfaces.

8. Finally, install the speaker grille. If desired, the

grille and frame may be painted to match the room

ecor. Use the piece you removed from the center

of the template as a painting mask to protect the

drivers and black baffle surface.
