WIRING
The most difficult part of installing in-wall loudspeakers
is running the wire. Pre-wiring new construction is
strongly recommended, but this is not always possible.
Access to a basement, attic, or crawl space can simplify
the task of getting wires to the appropriate locations. If
you are a do-it-yourself homeowner, you may wish to
hire a professional for the purpose of running the
wires, even if you are planning on mounting the
speakers yourself.
The terminals used on the MC300IW loudspeakers will
accept up to AWG #12 speaker cable. We recommend
using the largest wire that is practical to run in your
installation. A minimum of AWG #16 should be used
for runs up to 50 feet, with AWG#14 for runs from 50-
100 feet. Runs longer than 100feet should use AWG #12.
