Connections

Before connecting the iWS to your system, it is important that you turn off the power to all components to avoid
damage. Before installing the iWS, map out the wiring paths between the enclosure and the A1 amplifier. Make
sure that the speaker cable does not rest on sharp or pointed objects.
The iWS is designed for use with the A1 amplifier and X1 crossover. As it does not have an internal crossover and requires
these components, or it will not function properly. Proper wiring of the subwoofer is essential to good sound. At a mini-
mum, 14AWG 2-conductor speaker wire is recommended for runs of 10 feet or less, with heavier special purpose speak-
er wire used for longer runs. When permanently installing wire inside walls, be sure to use cable that is rated for
in-wall use and has special jacketing for fire prevention. In the U.S., the U.L. standard is CL-2, CL-3 and CM cable,
and in Canada the CSA standard is FT4 wire. The wires should be run in accordance with National Electrical Code
and any applicable local building codes. Prepare the wire by stripping 1/4" to 3/8" of insulation from the ends and twist-
ing the exposed wire strands tightly. The 5 way binding posts accept all types of wire ends.
Be sure to wire the subwoofer "in-phase." That is, the Positive (red) terminal on the amplifier output must be
connected to the corresponding Positive (red) terminal on the subwoofer. Likewise with the Negative (black)
terminals. All speaker wires have some sort of marking along one or both conductors to help you make the correct
nections. Take care to wire the subwoofer correctly in-phase, because once the wall is sealed there is no access to the
terminals.
