LOC90
ADD-ON AMPLIFIER ADAPTER
INTRODUCTION
The
LOC90
converts speaker wire (high-\eve\)
to
RCA
outputs (low-level)
for
the purpose
of
adding a 2-channel
or mono amplifier
to
an existing factory
or
aftermarket
stereo system. The
LOC90
features
up
to
4 volt output
and signal sensing turn-on with ability
to
drive a relay.
The
LOC90
also includes a convenient remote
mountable volume control for precise control over

ALL
manufacturers
warnings
regarding

bagsandelectricalsystems
in
your
vehicle.
We
recommend
the
use
of
a
volt-ohm
meter
or
computer-safe
LED
probe
when
checking
wiring. A
test
light
or
grounded
light
probe
if
used
improperly
can
cause damage
to
the
vehicle's
computer
and/or
diagnostic
system.
RECOMMENDED TOOLS
(not
included)
TESTING/DIAGNOSIS: Digital volt/ohm meter or electron-
ics-safe volt probe

WIRING
INSTRUCTIONS
TIPS:
For
easier installation,
connections
can
be
made
at
the
rear
speakers
in
many
vehicles
without
the
need
to
remove
the
stereo! The
LOC90
adapter
module
will
output
a +12V
remote
output
on
the
Blue/White
wire
when
signal
is
detected
from
the
car
stereo•s speakerwires. Wire
colors
on
the
LOC90
may
differ
from
the
wiring
codes
found
on
your
car
stereo/vehicle.
1. Connect the black wire
to
chassis ground (vehicle
metal).
2. Connect the yellow wire to a +12V constant
(continuous) power source.
TIP:
If amplifier is
installed nearby, tap the yellow wire from the
LOC90
into the amplifier•s +12V battery terminal
or
wire.
3. Connect the left speaker•s
+1-
input wires
to
the
white and white black input wires
of
the
LOC90.
This can be performed at the vehicle•
s
speaker
location
or
behind the stereo itself.
4. Connect the right speaker•s
+1-
input wires
to
the
gray and gray/black input wires
of
the
LOC90.
This
can be performed at the vehicle•s speaker location
or
behind the stereo itself.
5.
Connect the blue/white wire
to
the amplifier's
"remote turn-on"
or
"REM" input. Always refer
to
your amplifier's owner's manual forwiring details/
functions
of
your particular amplifier
(remote output: 500mA).
6. Connect the RCA audio outputs
of
the
LOCIO
to
the amplifier's inputs
{RED
=right channel, WHITE
=
left channel)
NOTE:
Some
mono
(monaural)
sub
amplifiers
may
have
only
a single RCA input. You can
choose
either
the
left
or
right
signal
from
the
LOC90,
but
it
is
advisable
to
use a
y-adapter
to
combine
together
for
maximum
signal level.3

WIRING COLOR CODES
NOTE: The wire colors on the LOC90 may differfrom
the wiring colors found on the car stereo I in vehicle.
Always refer
to the stereo owner's manual for wiring
details/functions for your particular car stereo. The
wire color codes used on the LOC90 conform
to the
standards set
by the E. I.A. (Electronics Industry As-
sociation).
White = Left front positive input (LF+)
White/black= Left front negative input (LF-)
Gray = Right front positive input
(RF+)
Gray/black = Right front negative input (RF-)
Yellow = +12 volt power input
(constant battery power)
Black= Chassis ground (vehicle metal)
Blue/white = +12V remote output (amp turn-on)
REMOTE SUBNOLUME CONTROL
The LOC90 includes on optional remote-mount volume
control to attenuate/control the newAMP/SUB system
level. Choose a location accessible
to the driver, pas-
senger or both. See Figure 1 on page 6 for
suggested locations.
TIP: Check for obstructions at the chosen location
before mounting/routing the volume control.
Recommended: Use the included adhesive strip for
non-permanent mounting. Optional: For permanent
mounting, use (2) small % •• screws (not included).

REMOTE SUBNOLUME CONTROL
FIGURE 1
ADHESIVE STRIP
1. Choose the desired location for the remote volume
control (Figure 1
).
2. Route the control cable from the selected location to
the LOC90 main unit.
3. Plug the male 3.5mm control wire into the female
3.5mm input
of the LOC90 module.
4. Peel the backing strip from one side of the adhesive
and attach to the remote volume control case. When
ready
to mount, peel away the remaining strip and
press the unit
to the mounting surface.
Optional: For additional support use 2 small screws
(screws not included). 6

ADJUSTING
THE
OUTPUT
LEVEL
NOTES:
The
LOC90
can output up
to
4 volts, a slight adjustment
can change the volume dramatically. The adjustment pots
rotate one complete turn,
do
not over-turn
or
use
too
much pressure.
Adjust gains with caution.
Too much volume or distortion
can damage your hearing
and the audio equipment.
1. Carefully break away the
screwdriver tool from the side
of
the
LOC90
case (Figure
2).
2. If using the remote volume control,
ensure that it is connected
to
the main
unit with its knob turned all the UP
(Figure
3).
3. Use the included tool at the
LOC90
module and turn both gain controls
aU
the way down (counterclockwise
until they stop -Figure
4).
4. Turn stereo on and adjust volume
up
to
%(or
just above loudest listening level)
5.
Carefully turn upthe left and right gain
controls (turn clockwise) on the
LOC90
until the sound is as loud
as will ever need
to
be or near
distortion (when sound becomes
garbled, unclear, or breaks up).
6.
Turn back each gain
level very slightly from
step #5 and then
immediately turn
down stereo volume.
7.
Ifyou hear a "hum"
or
excessive "hiss" sound
between songs then the gain
levels may still be adjusted
too
high.

TROUBLESHOOTING
NO
SOUND:
• Check and verify all electrical and signal connections.
-Speakerwire connections
to
LOC90
input
-Audio RCA cable connections from
LOC90
output
to
amplifier.
• Checkthat amplifier is turning on when stereo is on.
-Verify remote turn-on output (blue/white wire) from
LOC90
is connected
to
amplifier
-Verify that
LOC90
is receiving
+
12Von yellow wire and
black wire is connected
to
chassis ground.
Note:
If all
of
the above conditions are met, it may be
necessary
to
connect the
amp
lifer•s remote turn-on
terminal/wire directly
to
the carstereo
or
ignition.
• Check gain adjustment levels on
LOC90
• (If using remote volume control) check that the knob is not
turned all the way down.
