Our take on the JL Audio RBC-1

by Buck Pomerantz
JL Audio

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, 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 JX-Series mono amps, the RBC-1 controls the amp's level, from full mute to full volume.

Should Be Included as Standard Part

Written By VistaBlueGT, Ashburn, VA on Thursday, April 03, 2014
Crutchfield Customer Review (What's this?)
 
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.
Pros:
Simple
Cons:
Should be part of the amp, not an add on.

Convenient Adjusting

Written By C, Hilo,HI on Tuesday, October 15, 2013
Crutchfield Customer Review (What's this?)
 
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.

Necessary Accessory

Written By BillE, Fort Worth, Texas on Saturday, July 13, 2013
Crutchfield Customer Review (What's this?)
 
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.
Cons:
None.

Good

Crutchfield Customer Review (What's this?)
 
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

Don't leave home without it!

Written By Anonymous, PC, FL on Wednesday, June 13, 2012
Crutchfield Customer Review (What's this?)
 
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.

Great addition to JL amps!

Written By Anonymous, Columbus, OH on Wednesday, February 17, 2010
Crutchfield Customer Review (What's this?)
 
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.

JL Audio Bass Knob

Written By mark, Livermore, CA on Wednesday, September 17, 2008
Crutchfield Customer Review (What's this?)
 
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.

1 question already asked

Can you use 1 rbc knob to control 2 amps? Example: 2 500/1 jl amps using a phone splitter and controlling the bass on both. [ Jonathan  Jun 21, 2014 ]
9 answers
  • 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 ]
