CONNECTIONS
With the speaker placed at the desired
location, measure the distance from the
speaker to the amplifier. Use 18-gauge
speaker wire for a distance of 50 feet or
less. For a distance greater than 50 feet,
use heavier 16-gauge wire.
For the maximum bass response and
overall best performance, connect the
speaker in phase (– to – and + to +).
Speaker wire is either color-coded, with
a different color on each side, or coded
with a ridge or stripe on one side to iden-
tify the wire’s different sides, making the
connection easier. RadioShack stores
sell speaker wire to meet most needs.
Follow these steps to prepare the wire
and connect the speaker.
1. Separate the wire conductors for a
length of about 2 inches, then re-
move about
1 /
2
inch of insulation
from the wire’s ends using a wire
stripper.
2. Turn the speaker’s negative (–) ter-
minal counterclockwise to loosen it
and insert one of the wire ends into
the opening. Then turn the terminal
clockwise to tighten it.
3. Turn the speaker’s positive (+) ter-
minal counterclockwise to loosen it
and insert the other wire end into the
opening. Then turn the terminal
clockwise to tighten it.
4. Using the speaker wire’s coding as
a guide, connect the other end of
the speaker wire to the amplifier’s
corresponding (+ or –) speaker ter-
minals.
