1. Locate a suitable mounting location for the amplifier. The vertical wall
between the trunk and the passenger compartment is often a good
choice and is the method discussed in this manual.
2. Be sure that the amplifier fits properly and does not interfere with any
parts of the trunk lid or seat back.
3. Position the amplifier on the proposed mounting location. Using an
awl or other suitable tool, scribe the mounting surface where the
mounting holes are to be drilled.
CAUTION! As mounting the amplifier will require drilling, it is
absolutely necessary to make sure that no other vehicle components
could be damaged by the drilling process. If any vehicle component
could suffer any potential harm, select a different mounting location.
4. Carefully drill the mounting holes using a drill bit sized for a #10 sheet
metal screw.
5. Using the supplied #10 x 3/4” sheet metal screws, secure the remote
amplifier to the vertical trunk wall.
Wiring
Connecting to Power:
1. Using appropriately sized wire, extend the RED and BLACK wires
from the Main Power Connector, through the firewall and into the
engine compartment (refer to the Wire Gage Calculation Chart
located on the last page of this manual to determine the proper wire
size for your application).
2. Follow the factory wiring harness towards your vehicle’s battery.
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!
3. Install a user supplied 20A fuse block on the end of the RED wire.
Connect the fuse block to the battery using no more than 2 feet of
wire. Do not install the fuse into the fuse holder yet!
4. Connect the BLACK wire directly to the NEGATIVE battery terminal.
Connecting to your Speaker(s):
1. Route the ORANGE, and BROWN wires from both Siren Connector
#1 and Siren Connector #2 along the factory wiring harness towards
your speakers.
2. Connect the ORANGE wire from Siren Connector #1 to the
POSITIVE (+) terminal on speaker #1. Connect the ORANGE wire
from Siren Connector #2 to the POSITIVE (+) terminal on speaker
#2.
3. Connect the BROWN wire from Siren Connector #1 to the
NEGATIVE (-) terminal on speaker #1. Connect the BROWN wire
from Siren Connector #2 to the NEGATIVE (-) terminal on speaker
#2.
Hands-Free Siren (optional):
Refer to the wiring diagram for all wiring information for this optional
connection.
Radio Rebroadcast (optional):
The two (2) BLUE wires are used to connect your two-way radio’s external
speaker for radio rebroadcast. This is an optional connection and will not
effect the other operations.
Note: Radio rebroadcast will NOT work with amplified remote
speakers! If your remote speaker is amplified (I.E.: contains a power
amp circuit in the speaker assembly), do not enable the radio
rebroadcast feature.
Installation will be complete after a 20A fuse has been installed in the Main
Power Connector fuse block. Now inspect the fuses at the back of the
amplifier and at the battery. If either of these fuses are blown, carefully
inspect all of the circuit wires and make sure they are wired correctly.
Replace the blown fuses with ones of an identical amp rating. If these
fuses blow after installation or activation, contact Whelen Engineering
Technical Support.
