JL Audio amplifiers feature bass-boost circuitry to help you adjust low-frequency impact in your vehicle. The RBC-1 wired remote bass control works with all of JL Audio's A-Series, G-Series, RD Series, mono JX-Series, and most Slash v2 amps. You can mount the RBC-1 controller in the front of your vehicle and dial in the amount of bass you want from the driver's seat — mounting instructions, hardware, and a 18' cable are included.
Connect the RBC-1 to your amp, and it converts the amp's selectable bass boost (0 or 6 dB) to a variable boost (0 to 12 dB). With the Slash v2 amps, the RBC-1 takes the place of the amp's boost knob, allowing you to adjust your bass boost from 0 to 15 dB. With RD Series and JX-Series mono amps, the RBC-1 controls the amp's subwoofer level, from full mute to full volume.

Everybody needs this component with any amp..
Nice feature to have with the sub
Pros: Glad I made this purchase with the sub!
A definite must to go with the amplified subwoofer .
Great knob, always nice to be able to adjust the amp. For the JX amp it controls the level of the amp and not the bass boost which is what I prefer. Oh, the customer service when ordering this knob was awesome.
Highly recommend, A lot easier than adjusting the amplifier when you're going down the road.
This is a nice way to adjust bass control on the fly without having to get at my amp in the backseat. I only wish that, when turned all the way down, there wasn't still so much bass. The full spectrum from one end to the other is not all that great. I'd suggest dialing it in about where you want it set to the middle so that you can go a little up or down as needed.
Pros: Convenient Easy to set up
Cons: Limited power adjustment
Great accessory, I have no complaints other than I believe it should have come with the amp. But it doesn't, so purchase it anyways cuz u will enjoy its function
Pros: Easy installment. Does it's job.
Cons: Fact that it doesn't come with the amp upon purchase.
Easy install and works great
JL Audio Best of the best...
Pros: JL Audio #1 all the time...
Helps in being able to turn up or turn down the gain or volume on the subwoofer with out having to go to the controls of the amp or your head unit, thus for keeping you safer as you drive, because some music doesn't need as much bass but some music does, so you can adjust it from this switch. Also this switch can be placed any where inside your vehicle.
Pros: Easy access to volume, keeps you safer by keeping your eyes on the road.
excellent way to remotely control your bass, easy to install anywhere in your dash
Pros: works great
Simple to install and fits in most places. Plugs right into JX 500/1 and I use it to lower the bass; not as a volume control. You can use pretty much any phone cable instead of the super long one they provide. It is in the manual, but they use like pt 2 font so I missed it when I looked for that info...
Does have to go boom? No, no it doesn't. Love this little thing. Easy to install.
Pros: What is there to say? It is pretty cool to have that little knob to control the bass.
Cons: I wish there was some kind of resistance to it. Little clicks or something to indicate level.
If you have an amp, you gotta have this. Makes adjusting the bass boost extremely easy
Pros: Small, easy to mount, easy to use
This is a great addition to a PowerWedge+ that I installed with a factory head unit. Since the factory head unit has no subwoofer level control, being able to turn the bass down when listening to a podcast instead of music.
Pros: Great control of bass. Easy installation.
This little control knob makes it quick and simple to adjust the subwoofer up or down to fine tune the system to different music.
Pros: Easy to install and use.
Cons: Needs a colored mark or a notch to mark the subwoofer level, so it's easy to see in low light or nighttime.
Works great. Makes it very easy to adjust sub to different types of music to keep music from having too much or too little bass. A must with any sub/amp
I got this for my JL Audio JX250/1 amp, and I wouldn't want to have my system without it. It's great especially when passengers don't have the same appreciation for bass that I do :-)
Pros: Gives great flexibility to a powerful sub Easy installation
Bass is obviously song dependent and having this knob at your fingertip can save your sub. With all the loudness war and having compressed music that's a brick wall one can never be too careful. While dialing down the bass and turning up the volume your able to achieve more "punch" at freeway speeds. But it's also nice to have a lower volume and increase the bass knob to still get that "feel" when rolling through quieter neighborhood without announcing that you have quality subs. This is a MUST HAVE.
Pros: Quick easy control. Possibly save your sub. Cheap insurance.
Cons: Wish they would put a physically RAISED nub on it instead of the white hash tag. This way at night you know where the setting is or great to feel it when you don't want to take your eyes off the road. I took one of my daughter "diamond" stickers and super glues it there.
works with my JX500 to control the gain. It is nice as song types change to control the amount of bass that you are hearing.
Easy to follow installation instructions. GREAT remote control for Bass control from drivers seat; mounting where you are comfortable adjusting. Easy to hide or display as OEM, very small and unobtrusive. I don't know how someone could have one of the awesome JL amps and not have one of these!
Pros: Small, unnoticeable, easy to install without visible wires, great detailed instructions
Cons: None, not one
Bought this to control the output of a JL powermax subwoofer. Up to +12 db, works fine.
Pros: Ability to control subwoofer output up to +12 db or down to baseline.
This knob is pretty basic and works well. It's thoughtfully designed in that it has a small housing right behind the actual knob allowing for easier placement. Also, there is no gaudy branding or faceplate. When installed, you only see the knob. It mounts flush.
Pros: Simple, thoughtful design. It comes with spacers for a perfect flush mount. The cable is not proprietary, a standard phone line could be used. An optional metal knob is available from JL Audio.
Cons: The knob has a hash mark but it needs to be painted white. You can't see it in dim light. Also, it would be nice if it had a tactile detent at the mid-point. That said, you don't need either feature. You simply turn it down or up and can use your ear for that.
Pros: Tottally usable
This is an absolute must have for any subwoofer. Installed, you turn the gain completely up on the amp unit itself and then control the bass from a touch of a button at the front of your vehicle. Every song is different, has different types and amount of bass. This unit allows you to easily modify each song so that you have the perfect amount of bass every time. I only wish this invention was around for the older slash series of amplifiers. It is a TRUE bass control switch and you can install it anywhere you want that is easy for the driver to access.
Pros: Controls your bass output at the front of your car
Awesome. Simple install Plenty of cord to run or bundle!
Pros: Easy, works Great A++++
This remote switch makes adjusting the amplifier bass boost so easy and is so inexpensive that it should have been included with the the amplifier rather than as an option. Easy to connect using included RJ-11 phone connector and wire; is a simple attenuator, but very effective. Just turn your bass boost all the way up on your amp and use the RBC switch to find the right level or even mute it. The only problem I had was finding a location to install the knob. I might use velcro rather than drilling into my dash as a previous poster alluded to. Well worth the purchase and would recommend.
Pros: Easy to connect and use; adds convenience to bass boost adjustments rather than using a screw driver to turn the switch at the amp's location.
Cons: Having to run another wire.
Straight forward item. Connect to your amp, run the "phone" line to the front of your vehicle, or where ever you want the knob, and your done.
Cons: Should be part of the amp, not an add on.
great product. Easy to use. Very nice to adjust sub volume on the fly.. Then going into deck to change it. While driving..
I love having the ability to quickly and easily adjust the amp to give me the bass levels I want; however, with the price of the amp, this should have come with it. Build isn't particularly well throughout and executed, and it is a but difficult to place because of the awkward design.
Pros: I can easily make amp adjustments
Cons: Should have come with the amp, and the design could be better.
Makes controling your sub a lot easier
This RBC is a Great Thing to have if you are adding an JL Amp you can turn up the BASS or Turn it Down ...
Pros: very useful..
If you are purchasing a JL Audio amp to be used exclusively for a subwoofer, do yourself a favor and pick up one of these handy knobs. It's great or be able to adjust bass volume by song or by preference. For example, say your wife is riding with you and she,s just not that keen on a lot of bass. Simply dial it down and you can keep the volume.
Pros: Easy control of bass volume, great convenience, simple use.
JL has 2 remotes for there amps I didn't realize this until I had installed the wrong one ! Make sure to check which amp you have and what remote is compatable before ordering
Pros: does what it claims
I got this to control my JL Audio Slash 500/1v1. It works perfectly but is a little over priced for what it is. Would be nice to have some illumination so you could see what level it is set at night but I guess with this you should be tuning my ear anyway.
Pros: Works, plenty of cord length
Cons: pricey, lack illumination
this is a must have when dealing with a nice system ..my system is all jl audio w7 13.5 inch sub slash 1000 v1/2 amp 2 setrs of jl coponents ...each song has a different sound ...this bass control knob is awesome ..to adjust the bass on the fly ....awesome product
Pros: adjust bass volume without going thru head unit...
Cons: having to run another wire under carpet
This very simple little gain control makes all the difference in the world when it comes to on the fly quick sound quality adjustment. Rather than drop the bass frequency from a head unit and kill the overall sound quality or augment an in-deck subwoofer volume, this is worth it's weight in gold. If I want to jump from making my friends ears bleed with as few Hz at as high Dbs as possible then switch over to a James Taylor acoustical set, I can do it with a swipe of my finger.
Pros: Very small and extremely easy to install.
Cons: You have to dedicate a small space for this and probably drill a small hole in your dash. May be improved upon if it were in a small plastic encasing with stick on capability.
I paired this with my jl audio jx500/1d and it works great. Its perfect if you have others that ride in your car that are not crazy about bass.
This remote bass control works excellently and has been extremely handy, especially for city driving when there's a lot of people around. Plenty of cord, functions flawlessly, install is easy.
great product, works flawlessly.
Well this control works just like expected. Great to have quick control over the amount of pass my JL 10W3 is putting out as I listen to all kinds of music on a regular basis. I did want to pass along a few notes for others who are thinking of installing this. To get this to work on the amps you must have a few settings on the amp right: 1. The low pass filter on the amplifier must be turned on. 2. The bass boost switch must be turned to the on position. ...seems pretty obvious but these instructions are not included with the RBC-1 but can be found in the actual amplifier's manual. Lastly, I'm running the G4500 4-channel in a 3-way setup. The front channels are powering a pair of JL VR components and the rear channels are bridged to a 10W3. A nice touch to this is that the Bass Boost w/ the RBC-1 only controls the rear channels which is perfect for anyone looking for this type of setup!
If you need to control the amount of bass your JL Audio 500/1 amp is kicking out, this is the device. If you play a variety of music genres, you'll need some bass control. This product does exactly that.
This knob is pretty helpful. I like to listen to a pretty wide range of music, so when I change over from Rap to Country, this makes it easy to leave the settings on the radio alone and to just turn the knob to get the bass where I like it. I had the knob custom installed in the ash tray, but honestly it was a pain, so I had it moved to just underneath the armrest. If you get this, make sure you give it some fore-thought, as it where your installer should put it; otherwise, you'll regret it.

The AudioControl ACR-3 should give you the control you need. It takes time to get the DQ-61 set up but it gives you tremendous control. Good luck, and enjoy. [ Anthony Apr 30, 2017 ]
Anytime you can make your adjustments prior to amplification it is better. I would go with the ACR3 [ Brian Apr 29, 2017 ]
I would place the AC3 control at at least 80% gain, fixed, them would only adjust bass volume from the JL audio knob Once the DQ controls are set to your liking, typically all at 70-80%gain, place masking tape over them so they do not move inadvertently- then it's all controlled by your head unit [ Catalin Apr 29, 2017 ]
I am not technically qualified to answer this question, sorry. [ KEN Feb 20, 2016 ]
I can't know for sure but I suspect it would work. It seems like they're both similar and for similar purposes. If it didn't work, Crutchfield would likely accept the return. [ Jason Feb 19, 2016 ]
I tried on my Rockford Fosgate 500a2 using my Jl Bass knob and it increased the boost past the limits of my subwoofer so I think somehow regardless of using the same type phone cable they are different and I would recommend using the one that comes with your amplifier [ carlos Feb 19, 2016 ]
As long as the wires are in line, it should work. Worst case scenario is that you'll need to crimp a new phone end on with the correct alignment. The knob is just a potentiometer so it's nothing very high tech. [ JOSEPH Feb 19, 2016 ]
The permanent cable as shown in the picture is about 7" long. The removable cable that runs from the pictured device to the amp is just a standard phone cable. I don't recall if that is supplied, or how long it is. [ BRIAN Sep 01, 2015 ]
Not sure i installed all ready but is 6 to 8 feet long [ ALEJANDRO Aug 31, 2015 ]

I forwarded your question to an Advisor and they responded with the following: Honestly not sure. We did not carry that amp, so we don't have a compatibility listing for it. Best bet would be to call JL Audio directly at 954-624-0113 to confirm compatibility. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy Nov 13, 2014 ] Staff
no [ AFRIM Sep 09, 2014 ]
Ono it only works with jl audio [ JASON Aug 31, 2014 ]
Yes, the knob can work for two amps. You have to hook the knob to amp one and then use the preamps from amp one to amp two. Hope this helps. [ FRANK Jun 25, 2014 ]
I imagine if u bought a y connection to connect the two... ie telephone or ethernet cable with enough pins and it would control both at the same time... Contact JL audio for more accurate support [ BRIAN E Jun 24, 2014 ]
I would not recommend splitting this parallel pair phone line, as its name suggests it's a parallel pair of 24 ga. conductors with little to no shielding effect. As you may understand low voltage signals in car audio are very conducive to propagating noise created by your cars charging system. Further splitting this barely shielded conductor could possibly invite that noise into your amplified system. Then there is the impedance matching of the rheostat that varies the pre -amp voltage of the amp, with a split conductor it is possible to allow feedback between amplifiers causing even more headache. I would not recommend using one RBC-1 for 2 amps. After all they don't call them RBC-2's. [ JOSH J Jun 23, 2014 ]
I use this controller on 1 amp only. I will tell you that I love the added tuning I have with this control. [ DALE Jun 23, 2014 ]
Sorry, but I don't I know. I've only used 1 amb. Call Crutchfield or JL [ GARY J Jun 23, 2014 ]
Not shuer but it's worth a shot . The controler works well on one amp. I would think that if your trying to adjust two speakers on separate amps, it would be best to have two RBC knob controllers. That way it could be fine tuned. Or get a amp to control two subwoofer and one controler. The outher thing is the controler carries voltages, and not shure if sinding voltages to another amp will short out amp. Good luck with your project. [ JAVIER Jun 23, 2014 ]
I would like to say yes but I have not personally tested it but I think it will work for you so try it and let me know how it goes. [ DILLON Jun 23, 2014 ]
Yes you can control two amps with the single control. What you need is a rj11 phone splitter. The only catch is that the splitter must be a four wire and not a two wire dual line splitter. [ RICHARD Jun 23, 2014 ]
Don't know about that one [ JASON Jun 23, 2014 ]
