LOC2SL
ADD-ON AMPLIFIER ADAPTER
INTRODUCTION
The LOC2SL converts speaker wire (high level) to
RCA (low level) outputs for the purpose of adding a
2-channel or mono amplifier to an existing factory or
aftermarket stereo system. The LOC2SL also includes
a convenient remote-mountable volume control for
precise control over subwoofer amplifier level from up
front in the vehicle.

PRELIMINARY
BEFORE BEGINNING:
READ THESE INSTRUCTIONS!
**CAUTION**: Disconnect negative battery terminal to
avoid short circuits. Read ALL manufacturers warnings
regarding air bags and electrical systems 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
WIRE SPLICE/CONNECTIONS: Wire crimper/strippers,
soldering iron/heat shrink or buttsplice crimp connectors,
cable ties
SPECIALTY: Vehicle panel popper, trim removal tools, wire/
cable fishing puller tool

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 LOC2SL
adapter module will output a +12V remote output on
the Blue/White wire when signal is detected from
the car stereo's speaker wires. Wire colors on the
LOC2SL may dier 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 LOC2SL
into the amplifier's +12V battery terminal or wire.
3. Connect the left speaker's +/- input wires to the
white and white black input wires of the LOC2SL.
This can be performed at the vehicle's speaker
location or behind the stereo itself.
4. Connect the right speaker's +/- input wires to the
gray and gray/black input wires of the LOC2SL. 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 for wiring details/
functions of your particular amplifier.
6. Connect the RCA audio outputs of the LOC2SL to
the amplifier’s inputs (RED = right channel, WHITE =
left channel)
NOTE: Some mono (monaural) sub ampliers may
have only a single RCA input. You can choose either
the left or right signal from the LOC2SL, but it is
advisable to use a y-adapter to combine together
for maximum signal level.

WIRING COLOR CODES
NOTE: The wire colors on the LOC2SL may differ
from the wiring colors found on the car stereo / 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 LOC2SL conform
to the standards set by the E.I.A. (Electronics Industry
Association).
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 SUB/VOLUME CONTROL
The LOC2SL includes on optional remote-mount
volume control to attenuate/control the new AMP/SUB
system level. Choose a location accessible to the driver,
passenger 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 ¼'' screws (not included).

REMOTE SUB/VOLUME 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 LOC2SL main unit.
3. Plug the male 3.5mm control wire into the female
3.5mm input of the LOC2SL 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 LOC2SL gain controls are sensitive, 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 LOC2SL 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 LOC2SL
module and turn both gain controls
all the way down (counterclockwise
until they stop - Figure 4).
4. Turn stereo on and adjust volume up to
¾ (or just above loudest listening level)
5. Carefully turn up the left and right gain
controls (turn clockwise) on the
LOC2SL until the sound is as loud

as will ever need to be or near
distortion (when sound becomes
garbled, unclear, or breaks up).
Turn back each gain
level very slightly from
step #5 and then
immediately turn
down stereo volume.
If you 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.
- Speaker wire connections to LOC2SL input
- Audio RCA cable connections from LOC2SL output
to amplifier.
• Check that amplifier is turning on when stereo is on.
- Verify remote turn-on output (blue/white wire) from
LOC2SL is connected to amplifier
- Verify that LOC2SL is receiving +12V on 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 amplifer's remote turn-on
terminal/wire directly to the car stereo or ignition.
• Check gain adjustment levels on LOC2SL
• (If using remote volume control) check that the knob is not
turned all the way down.
•
If still no sound call tech support at 1-800-363-4490 x1.

ADAPTATEUR SUPPLÉMENTAIRE
D'AMPLIFICATEUR
INTRODUCTION
Le LOC2SL convertit le fil du haut-parleur en des sorties
(niveau élevé) à RCA (niveau bas) pour pouvoir ajouter un
monoamplificateur 2-canaux à un système de stéréo du
fabricant ou de marché secondaire existant. Le LOC2SL
comprend aussi une télécommande-montage commode
pour contrôler le volume; soit pour un contrôle précis
au-dessus d'un niveau de haut-parleur d'extrêmes graves à
partir du devant du véhicule.
