Mounting:
1. Locate a suitable mounting
location. The vertical wall
between the trunk and the
passenger compartment is often
a good choice and is the method
described in this manual.
2. Be sure that the remote amplifier
fits properly and does not
interfere with any parts of the
trunk lid or seat back.
3. Position the amplifier onto the
mounting location. Using an awl or
other suitable tool, scribe the
mounting surface where the
mounting holes are to be drilled.
4. Carefully drill the mounting holes using a #16
drill bit.
5. Using the supplied #10 x 3/4” sheet metal screws, secure
the remote amplifier to the vertical trunk wall.
Wiring / Power:
WARNING! All customer supplied wires that connect to the positive
terminal of the battery must be sized to supply at least 125% of the
maximum operating current and FUSED at the battery to carry that load.
DO NOT USE CIRCUIT
BREAKERS WITH THIS
PRODUCT!
1. Extend the two (2)
RED wires along the
factory wiring harness
to the POSITIVE +12VDC battery terminal.
2. Connect the RED wires to one end of a user supplied fuse block.
Do not connect this fuse block to the battery yet.
3. Extend the two (2) BLACK wires along the factory wiring harness to
the NEGATIVE battery terminal.
Control Switches:
This siren amplifier has six control inputs available, however; not all
control inputs will need to be wired depending on the “Mode of Operation”
chosen by the user. Five of the control inputs (CNTRL 1-3, air horn and
horn ring) are activated by applying positive voltage (Vbat) to them, the
RED/WHITE wire (pin 14) is a current limited output that can be used for
this purpose (see wiring diagram).The last input (CYCLE) is activated by
applying ground to it. Refer to the Air bag warning on Page 1 before
extending any wires into the interior of the vehicle.
Speakers:
1. Extend the ORANGE, YELLOW and BROWN wires along the factory
wiring harness towards your speakers.
2. Connect YELLOW wire to POSITIVE (+) terminal of speaker #1 and
ORANGE wire to POSITIVE (+) terminal on speaker #2.
3. Connect BROWN wire to NEGATIVE (-) terminal on both speakers.
Operation:
Siren in use: This output will become active (+VBAT) whenever a tone is
being produced by the siren.
Modes: There are 3 modes of operation. Mode 1 is the factory default
mode. See “Mode Programming” to change the mode of operation.
