Speaker wire has two individual conduc-
tors (wires) covered with insulation, and
is often marked to help you make the
proper connections. Insulation on one
side of the wire mi
g
ht have a rid
g
e or
colored stripe. Or, the two conductors
mi
g
ht be different colors (silver and cop-
per, for example).
For the best bass response, be sure to
connect + on the speaker to + on the
amp, and – on the speaker to – on the
amp.
1. Separate the conductors at each
end for about two inches, then strip
1
/
2
inch of insulation from the end
of each conductor.
2. Unscrew the speaker’s positive (+)
terminal and insert a conductor’s
stripped end into the hole on the
side of the terminal post.
3. Hand ti
g
hten the terminal to secure
the wire in place.
4. Connect the conductor’s other
stripped end to the amplifier’s posi-
tive (+) terminal.
5. Repeat Steps 2–5 to connect the
speaker to the amplifier’s ne
g
ative
(–) terminals.

dioShack Cat. No. 42-2470) to connect
