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.
