Preparing for Installation

Map out the wiring paths from the speakers to the amplifier. We recommend 18-gauge wire for runs up to 25 feet, and 16-gauge or thicker 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.

Each speaker is 8 ohms nominal. When connecting more than two speakers per amplifier channel, you should use series/parallel wiring or line transformers. In all cases, make certain that the total impedance does not fall below the amplifier’s minimum rating. If you are not sure, contact your Boston Acoustics dealer.

Use the cable clamp supplied to secure the speaker wire to the housing. Press the clamp into one of the holes on the printed circuit board.

You Will Need

1.A utility knife, an electric jigsaw, or another means of cutting a hole in the mounting surface.

2.Phillips and flat-blade screwdrivers.

3.A wire cutter or stripper for preparing the speaker wires.

4.An awl or a small screwdriver to remove the speaker grille.

With the hardware supplied, the speaker can be installed in existing walls and ceilings from

38" (9.5mm) to 112" (38mm) thick. For thinner walls, you will need to use spacers (not provided) for the mounting bracket. In walls greater than 112" (38mm) thick, you will need longer screws.
