Electrical power connections to the amplifier are made using a removable
connector located on the back of the amplifier case. Communication between
the control head and the amplifier are made via a special communication cable.
CAUTION: Please note that this cable IS NOT a standard telephone cord and
CANNOT be replaced with one. You should make all electrical connections to the
power connector before installing the connector on the unit. If the unit needs
service, both the communication cable and the power connector can be easily
removed without unwiring the connector.
The power supply of the unit must be capable of delivering peak currents up to 50
amps for adequate short circuit protection and reliable operation. The preferred
source is directly at the vehicle battery. The unit is internally fused. A wiring diagram
on the next page shows detail of how to wire the power connector on the amplifier
to the vehicle. The communication cable has both ends identical, and should have
one end plugged into the amplifier (RJ11 port) and the other end plugged into the
control head (RJ11 port).
Electrical Connections
AMPLIFIER
CONTROL HEAD
Electrical power connections to the control head are made using one male and
one female spade terminal. Communication between the control head and the
amplifier are made via a communication cable with an RJ11 connector. The black
wire included in the kit with the female terminal should be plugged into the male
spade terminal on the back of the control head. The red wire included in the kit
with the male terminal should be plugged into the female terminal on the back of
the control head. The communication cable has both ends identical, and should
have one end plugged into the amplifier (RJ11 port) and the other end plugged
into the control head (RJ11 port)
Please Note:
This is NOT a standard telephone cable.
