CAUTION
Before installation, disconnect the battery neg-
~
alive (-)terminal to prevent damage to the unit,
fire and/or possible injury.
~CAUTION
Avoid running
power
wires near the low level
input cables, antenna, power leads, sensitive
equipment or harnesses. The power wires car-
ry substantial current and could induce noise
into the audio system.
1. Plan the wire
routing.
Keep RCA cables close together but isolated
from the amp I ifier's power cables and any high power auto accessories,
especially electric motors. This is done to prevent coupling the noise
from radiated electrical fields into the audio signal. When feeding
the wires through the firewall or any metal barrier, protect them with
plastic or rubber grommets to prevent short circuits. Leave the wires
long
a
t this point to adjust for
a
precise fit at a later time.
2. Prepare the RED wire (power cable) lor attachment to the amplifier by
stripping 1/2" of insulation from the end of the wire. Insert the bared
wire into the B+ terminal and tighten the
set
screw to secure the cable
in
place.
NOTE:
The B
+ cable
MUST be fused 18" or less from the
vehicle'
s battery.
Install the fuseholder under the hood and ensure
connections
are water
tight.
3.
Trim the RED wire (power cable) within
18"
of the battery and
splice
in
a inline fuse holder (not
supplied).
See Specifications for the rating of
the
fuse
to be used. DO NOT install the fuse at this
time.
4. Strip 1/2" from the battery end of the power cabl
e
and crimp an
appropriate size ring terminal to the
cable.
Use the ring terminal to
connect to the battery positive terminal.
5. Prepare the BLACK wire (Ground cable) for attachment to the amplifier
by stripping 1/2" of insulation from the end of the wire. Insert the
bare
wire into the GROUND terminal and tighten the set screw to secure the
cable in place. Prepare the
chassis
ground by scraping any paint from
the metal surface and thoroughly clean the area of all dirt and grease.
Strip the other end of the wire and attach a ring connector. Fasten the
cable
to the
chassis using a non-anodized
scre
w and a star washer.
NOTE: Keep
the
length of the BLACK wire (Ground)
as
short as possible.
Always less than
30".
6. Prepare the Remote turn-on wire for attachment to the amplifier by
stripping 1/2"
of insulation from the end of the wire. Insert the bared
wire into the REMOTE terminal and tighten
the
set screw to secure the
wire in place.
Conne
ct
the
other end of the Remote wire to a switched
12 volt
positive
source.
The
switched voltage is usually taken from the
source unit's remote amp on lead. If the source unit does not have this
output
available, the
recommended solution
is
to wire a mechanical
switch in
line
with a 12 volt source to activate the amplifier.
7. Securely mount the amplifier
to
the vehicle or amp
rack.
B
e
careful not
to mount the amplifier on cardboard or plastic
panels.
Doing
so
may
enable the
screws
to pull out from
the
panel
due
to road
vibration
or
Installation
sudden vehicle stops.
8. Connect from source signal by plugging the RCA cables into the input
jacks at the amplifier.
NOTE: All "ACTIVE" inputs must have RCA jacks connected. Switch in
2CH. position,"ACTIVE" - Front channel inputs
only.
Switch in 4CH.
position,"ACTIVE"- All Front and Rear channel
inputs.
When connecting
to the 4-Channel inputs, be sure to route both front and rear RCA cables
tightly together.
~CAUTION
Always ensure power is
off
or disconnected at
the amplifier before connecting RCA
cables.
Failure to do so may cause damage to the am-
plifier and/or connected components.
9. Connect the speakers. Strip the speaker wires
1/2"
and insert into the
speaker terminal and
tighten
the set screw to secure into place. Be
sure to maintain proper speaker
polarity.
DO NOT chassis ground any
of the speaker leads as unstable operation may result.
10. Perform a final check of the completed system wiring to ensure that all
connections are
accurate.
Check all power and ground connections
for frayed wires and loose connections which could cause problems.
Install in line fuse near battery
connection.
NOTE: Follow the diagrams for proper signal polarity.
