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.

Other than being bulky in an otherwise tight compartment, the SLC4 was relatively easy to install. However, making changes to it was not as easy as advertised. Regardless, I figured it out with the help of Crutchfield. It was a necessary evil.

works as expected especially since it came pre attached only could have done a better job of securing the wires in their respective locations


 
Works just fine October-20-16
Reviewer: Tom from Folsom, CA  
Application: 1999 Mercedes Benz SL500.  I read many of the reviews about this product before I purchased and was a little concerned about the durability of the unit.  It's true that you need to take care not to over-tighten the wire connection screws but, if you're careful and take your time, you shouldn't have any problems.  A couple of tips: 1) after you've connected the speaker wires to the unit, put a zip-tie or 2 around those wires for added stability. 2) if you're putting this on a Benz, remove the climate control module above the stereo cavity to give yourself more room in maneuvering the unit into a safe place back behind the receiver/stereo unit. I was able to get my hand back in the cavity to guide this unit to a "safe place" behind the receiver/stereo 3) there is a selector switch on the side of the unit (line out, factory amp, common ground); ONCE YOU'VE DETERMINED THE CORRECT SETTING FOR YOUR VEHICLE, apply some duct tape or clear silicon caulk to keep that selector switch in it's appropriate position because it's a tight fit behind the receiver/stereo and it could move from the correct setting.


 
Necessary evil October-16-16
Reviewer: Anonymous person from Austin, TX  
Used in my 2004 BMW with HK sound system between new headunit and factory amp & speakers. I'm not sure of an alternative to work with this old set up, so it is a necessary evil. In general, it works and is inexpensive. Things to keep in mind:
* This thing is Huge (relatively speaking). I could not fit it behind my headunit so it took hours of extra time and wiring to find it a new home.
* Wiring connections for speakers are fragile and insecure.
* Adjusting the gain pots is imprecise at best.
* Sound quality from it is marginal.
That all said, I'm not sure of an alternative for this setup.
