Features

Overview: This is a versatile adapter that allows for multiple applications. If your receiver doesn't have preamp outputs and you want to connect it to an amp that doesn't have speaker level inputs, this adapter can be used to convert you receiver's speaker level outputs into preamp outputs. With this adapter, you can hook either a 2-channel or 4-channel amplifier to this adapter, and not lose fader control. This adapter also allows you to add an aftermarket receiver to either a common ground audio system in your vehicle, or an audio system that has factory amplifiers (like many of the Premium, JBL, and Bose audio systems). There are gain controls for both the line outputs and the factory amp inputs. Which gain controls you use depends on your application. Note: There is a plastic screwdriver that is physically attached to the adapter, and must be broken off to use. It is used to adjust gain controls and screw down the speaker terminals.

Speaker-Level-to-Line Level Conversion: The adapter can convert car stereo speaker outputs to RCA outputs so an external 2 or 4 channel amplifier can be added to a car audio system. There are line output controls that allow you to adjust the output level going into your amplifier(s). The adapter can handle up to 80 watts of speaker level input.

Interface with Factory Amplified Systems: This adapter allows the matching and installation of an aftermarket receiver with most factory amplified systems like the Premium/JBL/Bose systems.

Subwoofer Application: The adapter will allow for the integration of a subwoofer or subwoofers to nearly any audio system. There are line output controls that you can use to adjust the output level going into your amplifier(s).

Common Ground Audio Systems: With this adapter, you can add an aftermarket receiver to a common ground system in your vehicle without having to run new speaker wires. There are factory amp gain controls that you can use to adjust the input levels.

Common Ground/Factory Amp/Line Out Switch: Depending on how you are using the adapter will depend on what position the switch will be in. If you are adding a new receiver to a common ground system, then the switch is put into the "Common Ground" position. If you are adding the receiver to a factory system that uses Premium, JBL, and or Bose, then the switch is put into the Factory Amp position. You can also add an external amp to a receiver that does not have line outputs; in this case the switch will be in the "Line Out" position. There are factory amp gain controls that you can use to adjust the input levels.

Great Little Device September-13-16
Reviewer: Ben S from Thomasville, NC  
This was originally one of those add-on items I really didn't know what was for. After installing the radio by directly connecting the wiring harness to the stereo, I noticed that I was getting some mild distortion at higher volumes. I called Crutchfield support, and this little device (which I previously wasn't sure what was for) solved all of my problems. It connects between the two wiring harnesses, and allows the user to adjust the gain sent to the factory amp.


 
Not Even Worth It For Free September-12-16
Reviewer: Kevin from Pittsboro, NC  
The Scosche SLC4 cannot do what it was intended to do.  This is solely the fault of the connection scheme, which cannot stay fastened no matter how hard you tighten the screws.  If you think you have it tightened enough, you don't:  it can't survive being smushed in to the dash cavity without something coming loose.  Cars by definition move and twist and bump, they have forces that act on them in all directions.  You can't use a product that you can't rely on staying connected once you've reassembled the dash.  Don't be fooled by the low price; it still isn't worth it if was free.

In its place I used the Posi-Products Connector Kit from Crutchfield, and two PAC SNI-35 Two Channel LOCs with two Rockford Fosgate RFI2SW RCA to Speaker Wire Adapters from another vendor.  The PAC product I think sounds better (for the minute or two I had the Scoshce connected properly), but the bottom line is it has a reliable connection, and that is what matters most.  The Scosche product could solve its problem entirely by skipping the screw connectors and going with hard wired internal connections that you can twist connect with products like the Posi connectors or other crimping or soldering methods.


 
Works fine - easy to install September-12-16
Reviewer: EngineerBill from Los Altos, CA  
This adapter works just fine to connect my new JVC radio to the existing Bose system in a 97 Mercedes C280.  The screw connectors for the input wires are just fine if you pay attention to how they work before you start turning the screws too much.  The screws push down on a metal strip that grips the wire very firmly.  Make sure the screw is backed off enough to open up the space for the wire then insert wire and tighten down the screw until you can't pull the wire out of the jack.
