Follow the wiring diagram on the back of this page. Carefully map out the wiring path from the amplifier to
the AT-780S and from the AT-780S to the main speakers. We recommend a minimum of 16 gauge wire for this
installation. Be sure that the speaker wire does not rest or rub against any sharp or pointed objects. The speaker
should be mounted on a flat surface to form a good seal between the speaker flange and the mounting surface.
Make a 225mm(8.858") square cutout and run wire from the amplifier to the cutout. Strip approximately 1/4"
off the wire ends, and tightly twist the wire strands. Connect the wire to the speaker, carefully observing polarity (+
and -). Mount speaker in the wall using the included screws.
