Preparing for Installation
Map out the wiring paths from the speakers to the amplifier. We recommend
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. Affix the clamp to one of the screws used to hold the printed circuit board to the housing.
You Will Need
1.A utility knife, electric jigsaw or other means of cutting a hole in the mounting surface.
2.Phillips and
3.A wire cutter or stripper for preparing the speaker wires.
4.An awl or small screwdriver to remove the speaker grille.
With the hardware supplied, the speaker can be installed in existing walls and ceilings from 3⁄8" (9.5mm) to 11⁄2" (38mm) thick. For thinner walls, you will need to use spacers (not provided) for the mounting bracket. In walls greater than 11⁄2" (38mm) thick, you will need longer screws.
