Scosche LOC2SL Line Output Converter
Scosche is a consumer electronics and car audio product company that specializes in creating various accessories for mobile devices and vehicles. The company was founded in 1980 by Roger and Scotia Alves and is headquartered in Oxnard, California, USA.
Scosche offers a wide range of products designed to enhance the functionality and convenience of mobile devices and vehicles.
The LOC2SL converts speaker wire (high level) to RCA (low level) outputs to add 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 the subwoofer amplifier level from up front in the vehicle.
READ THESE INSTRUCTIONS!
CAUTION: Disconnect the negative battery terminal to avoid short circuits. Read ALL manufacturer’s warnings regarding airbags 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.
- TESTING/DIAGNOSIS: Digital volt/ohm meter or electronics-safe volt probe
- WIRE SPLICE/CONNECTIONS: Wire crimper/strippers, soldering iron/heat shrink or butt-splice crimp connectors, cable ties
- SPECIALTY: Vehicle panel popper, trim removal tools, wire/ cable fishing puller tool
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 the signal is detected from the car stereo’s speaker wires. Wire colors on the LOC2SL may differ from the wiring codes found on your car stereo/vehicle.
- Connect the black wire to the chassis ground (vehicle metal).
- Connect the yellow wire to a +12V constant (continuous) power source. TIP: If the amplifier is installed nearby, tap the yellow wire from the LOC2SL into the amplifier’s +12V battery terminal or wire.
- 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.
- 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.
- 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.
- Connect the RCA audio outputs of the LOC2SL 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 LOC2SL, but it is advisable to use a y-adapter to combine 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 the 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 an 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
- Choose the desired location for the remote volume control (Figure 1).
- Route the control cable from the selected location to the LOC2SL main unit.
- Plug the male 3.5mm control wire into the female 3.5mm input of the LOC2SL module.
- Peel the backing strip from one side of the adhesive and attach it 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).
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.
- Carefully break away the screwdriver tool from the side of the LOC2SL case (Figure 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).
- Use the included tool at the LOC2SL module and turn both gain controls down (counterclockwise until they stop – Figure 4).
- Turn the stereo on and adjust the volume up to ¾ (or just above the loudest listening level)
- 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 the sound becomes garbled, unclear, or breaks up).
- Turn back each gain level very slightly from step #5 and then GEKED immediately turns down the stereo volume.
- If you hear a “hum” or excessive “hiss” sound between songs then the gain levels may still be adjusted too high.
- 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 the amplifier is turning on when the stereo is on.
• Verify remote turn-on output (blue/white wire) from LOC2SL is connected to an amplifier
• Verify that LOC2SL is receiving +12V on yellow wire and the black wire is connected to chassis ground.
• Note: If all of the above conditions are met, it may be necessary to connect the amplifier’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 down.
- If still no sound call tech support at 1-800-621-3695 x3.

FAQS About Scosche LOC2SL Line Output Converter
Is power required for a line output converter?
To generate the current required to operate the turn on circuitry and produce a dependable remote signal, the LOC must be connected to 12v+ and Ground.
What impact do line output converters have?
They also facilitate the production of sound with higher quality.
A speaker to line level converter is what?
Speaker Level Outputs to Line Level Signals Converter
Is a ground required for a line output converter?
The shield of the RCA output cables to the head unit is grounded using these wires.
What voltage does a converter become necessary?
If your device only operates on 110 to 130 volts
What is the voltage on the line?
Peak to peak 2 volts
What is the converter’s primary purpose?
DC to AC power conversion.
What distinguishes a LOC from a high level?
In essence, a LOC takes a high-level signal—typically from a factory source—and lowers it to a level that your aftermarket gear’s inputs can safely tolerate.
What distinguishes line input from line output?
Line inputs have an impedance of 10,000 ohm (10k ohm), whereas line outputs commonly have signal impedances between 100 and 600 ohm.
What level of output is there?
The rating for consumer line level is -10dBV.
