12 Connecting Inputs
CONNECTING SPEAKERS
You can connect four speakers, two speak-
ers and a subwoofer, or just two speakers to
the amplifier and your auto sound system.
Important: Before you make the connec-
tions, make sure both
BRG/ST switches (on
the left and right sides of the amplifier) are
set to
ST .
Preparing the Speaker Wires
Caution: You must connect a separate wire
to each speaker terminal as described in the
following procedures. Only use a common
ground wire or chassis ground if your auto
sound system is wired for it.
Notes:
• Use 16- or 18-gauge marked or color-
coded wires to help you correctly con-
nect the speakers to your amplifier.
• Color-coded wires have a stripe running
down one of the conductors or different
colored insulation for each conductor.
Your local RadioShack store has a wide
selection of speaker wire.
• For the maximum bass response and
the best overall performance, keep your
speakers properly phased (connect + to
+ and – to –).
1. With the speakers placed in their
approximate locations, run one wire
from each speaker to the amplifier.
If you are connecting a subwoofer, run
two wires from each of the subwoofer’s
terminals to the amplifier.
2. Separate each wire’s two conductors at
both ends for a length of about 4 inches.
3. Strip the insulation from the ends of
each conductor to expose 1 / 4 inch of
wire. Twist the ends to secure loose
strands.
