INPUT CONNECTIONS

Connect the front and rear RCA input jacks of the Amplifier to the outputs of the Source Unit (i.e.,
radio, cassette player or CD player). If line level output is not available, connect the speaker out-
puts of the source unit to the Speaker Level input of the amplifier.

Figure 9: High/Low Impedance Inputs
Note: Connect the black ground wire to the source unit ground only if alternator noise is
present.
Connect the Amplifier to the Speakers. Use thicker speaker wires (e.g. 8 - 10 gauge desirable) for
these connections.
FOR STEREO MODE
Note: We recommend a total speaker load of 2, 4 or 8 ohms per channel
1. Connect the front left negative ("–") speaker output of the amplifier to the negative terminal of
the left speaker.
2. Connect the front left positive ("+") speaker output of the amplifier to the positive terminal of
the left speaker.
3. Connect the front right ("–") speaker output of the amplifier to the negative terminal of the right
speaker.
4. Connect the front right ("+") speaker output of the amplifier to the positive terminal of the right
speaker.
5. Repeat the same for the rear channel speaker connections.

FOR BRIDGED (MONO) MODE
Note: For bridged mono mode, we recommend a total load of 4 or 8 ohms.
1. Connect the front left positive ("+") speaker output of the amplifier to the positive input terminal
of the speaker.
2. Connect the front right negative ("–") speaker output of the amplifier to the negative input termi-
nal of the speaker.
3. Repeat the same for the rear channel.
4. Make sure that ALL RCAs (front and rear left/right) are plugged in, other wise bass response
and output will suffer.
