Using 18 gauge wire, connect the
speaker leads (58W speakers to SPEAKER LO
POWER or 100W speakers to SPEAKER HI POWER)
as shown in Power Cable Wiring Diagram, figure 3-6.

Radio.
To allow incoming radio messages to
be rebroadcast over the outside speakers, connect the
two brown zip cord leads (pins 9 and 12 of the power
cable) across the two-way radio’s speaker.
3.
Horn Ring.
In order to utilize the horn ring control
of siren tones (Tap II) and other features of the siren,
the following procedure must be performed.
a.
Locate the wire that connects the
vehicle horn ring switch to the horn or horn relay.
Cut this wire.
b.
See figure 3-7. Splice the white/

A.
Power Cable Connections.
The power cable included in the carton is
equipped with a twelve-pin plug that mates with the
connector on the rear of the Amplifier Unit (see
figure 3-5). The cable is supplied with a 20-ampere
in-line fuse. Additional wire (the same gauge or
heavier) may be spliced to the leads as required. The
various wires on the connector must be connected as
follows:
1.
Speaker.
The unit is designed to operate with
one 11-ohm impedance speaker or two 11-ohm
impedance, low power (58W) or high power (100W),
speakers connected in parallel and in phase. On
Federal speakers, this can be accomplished by
connecting the two speaker leads marked “1” to the
SPEAKER COMMON power cable lead and the two
speaker leads marked “2” to the SPEAKER HI
POWER or SPEAKER LO POWER power cable
leads. See figure 3-6.
