More details on the EFX Remote Level Control

Mark G.

Product Research


Remote Level Control: The Scosche EFX RLC is a universal remote level control for your amplified car stereo system. It allows you to adjust the level of your amplifier from the front seat. This remote level control is simply connected between your car stereo's RCA output and the RCA input on your aftermarket amplifier, using a stereo RCA cable (sold separately). The Scosche EFX RLC only has a stereo left/right input and output, so its perfect for a sub-channel level control. If you need it to control additional channels, then you will need to purchase Y-adapters (sold separately). All channels connected to the RLC will share the same level control.

Mounting Options: The Scosche EFX RLC includes two screws to mount the remote level control under the dash.

Customer Q&A

Crutchfield asked: Why did you buy this?
The amp I chose did not come with a bass knob or have an option for one. [ Marco  Dec 30, 2018 ]
I don't have a eq so volume in bass is in radio and some music change on bass An to hard to drive an change bass setting In radio setting so I like this one because RCA PLUG IN AN DON'T NEED EQ BECAUSE RADIO HAS ONE THANK YOU [ Marty  Sep 23, 2018 ]
I really wanted a way to control the bass of my daily driver just so I'm not bumping in my neighborhood when I leave at 3AM and when I arrive at work. But when I leave out of the office, I can crank my bass back up and enjoy the ride home. [ Tyler  Jun 29, 2018 ]
RCA in-line volume control. Variable attenuator. Needed this to adjust the volume running to my RCA input amplifier that has no volume control built in. Another product I bought on amazon gave me terrible buzz/hum. Hopefully this one is of better quality! By the reviews, it looks to be a winner! [ Alex V.  May 10, 2018 ]
Works very well to control bass level for different types of music. I have one in my truck and I love it. A whole lot better an easier than having to go in the menu on my head unit to adjust bass level this is the fourth one I'm buying, one for me two for my 2 younger Son's vehicles An now one for my older boy. Good product. [ Rodney  May 05, 2018 ]
I have used this knob before,,it is cleaner than the LC-1,,and no problems with it [ dennis  Sep 12, 2017 ]

I Needed extra volume between the stereo head unit and the preamps [ David  Sep 04, 2017 ]
I wanted a bass knob for my subs in my car [ Anthony  Aug 21, 2017 ]
Hv a turntable with a preamp directly into powered studio speakers...but they have individual volume controls. [ Gregory  Jul 09, 2017 ]
Looking for a remote volume control for the subwoofer in my pick up. This looks like I can remove the case and mount the control using a simple hole in the dash for a cleaner install. [ Legs  Apr 24, 2017 ]
To control the gain of the subwoofers. [ Michael  Mar 27, 2017 ]
My amp didn't come with a level control so I got two rca cables to utilize this level control [ Colin  Mar 17, 2017 ]
Wanna be able to quickly turn down my sub. [ cody h.  Jan 30, 2017 ]

Want to be able to control my bass. [ scott  Jan 04, 2016 ]

My car does not have RCA outputs. Will this product still work?
[ Bbraught  May 17, 2019 ]

I use this as a patch through from my radio to my sub amplifier. It works like a volume/cut off when I wish to throttle down the lows in certain situations or songs. It could work for any addon amplification. But the signal has to come into and go out. If you don't have RCA outputs you will have to either try another product or rig it differently than I explained above which is what they are intended for. Sorry
[ Ivan  May 24, 2019 ]
Can I use this in line after the amp (speaker outputs) to control volume to a set of speakers?
[ Joe  Aug 23, 2018 ]
1 answer
No, you'll need a volume control for that. This is only to control the line level voltage-
[ AVI  Aug 31, 2018 ]
My Kenwood amp doesn't have a plug in for a remote like most other amps have . Is this basically the same thing as the other bass level remotes ?
[ Billy  Jan 05, 2018 ]

Yes, it just controls level coming into the amp. I found it easier than the ones amp specific, because you can just install it in-line right at the head unit where it going to be mounted anyway. Works great
[ Cody  Jan 10, 2018 ]
Yes it is. It works fantastic for the price
[ Bruce  Jan 09, 2018 ]
Is this actually cutting power the the sub channel or is it more of an eq knob?
[ DEAN  Aug 30, 2017 ]
1 answer
This is not cutting the power the amp gets, but it is cutting down the level, or the power, of the audio being fed into the amp. And that cuts its volume levels of the bass audio you hear. HTH! My Bio:
[ Paul  Sep 02, 2017 ]  Staff
How would you connect this to use this as a master control for the car stereo volume instead of as a subwoofer level adjustment?
[ Michael  Apr 18, 2016 ]
2 answers
I have actually used this with the rca Bluetooth receiver. the BT plugs into the input on this volume control and the out goes right to the amp bypassing any need for a head unit. I just use my ipod, phone as the music player.
[ ezekiel  Apr 19, 2016 ]
I'm not sure that is even possible seeing as it is made for adjusting the level of power being sent to the amp via the RCA wires. I purchased a receiver that comes with a remote control so I can control volume without focusing on the deck while driving, It's right in the palm of your hand!
[ Jonathan  Apr 19, 2016 ]
how many watts is it rated for? What is the impedence? How many Ohms?
[ Donald  Sep 18, 2015 ]
2 answers
This is just plugged into the RCA jack in line and run to your amp, it's not powered by your amplifier. Hope this helps.
[ James  Sep 18, 2015 ]
This doesn't require rating on Watts or Impedence. It simply attenuates the Pre-amp signal from your stereo head unit. If turned all the way up it allows the full strength signal produced by your head unit to pass. If you turn the dial down it reduces the signal from your head unit before it gets to the amp. It's like a volume control for select channels
