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.

Does the job July-13-15
Reviewer: PhilH from New York  
Crutchfield included this in my installation kit to interface between my JVC KD-R660 and my 07 Pontiac Vibe with the factory Monsoon audio system. The Scosche SLC4 was necessary to adjust the line output from the receiver going into the factory amp.

Works as advertised. Paired this with a alpine frv300 amp for mids and highs and made a huge difference over Stock head unit.


 
Didn't know I needed it, Crutchfield did June-24-15
Reviewer: da from Florida  
Researching the stereo for a non-specified vehicle, I saw the install kit.  When I specified the vehicle, the kit price jumped to twice as much and this device was included.  I didn't think I needed it, but Crutchfield knew better.  Glad I trusted them, because if I had just bought the stereo, I'd be pulling my hair out, scrambling to find a way to properly run the stereo to the factory amp.


 
You will need this June-21-15

You will need this to wire a stock radio to a RCA amp.


 
Simple and effective, but a warning! June-21-15
Reviewer: John from Kansas City, Mo  
I needed this unit to wire my alpine head unit to a 5 channel amplifier.   The head unit only had RCA outputs for the subwoofer, and just the wire harness for the rest of true channels, and they were amplified by the internal amplifier, so this unit was the converter I needed.    

The instructions were very straight forward and easy to understand, and taking my time I had zero issues with the connections required.    

WARNING:  Make sure you adjust the levels on this unit BEFORE you stuff it in the dash and install your cosmetic trim, or you'll get zero sound from your new amplifier, causing at least 3 minutes of confusion and head scratching.  Derp.    

Overall, an excellent product that performs well.   Crutchfield's tech support and customer service are, as always, TOP NOTCH!  5 stars all around.
