Our take on the JL Audio HD-RLC

The HD-RLC remote level controller works with JL Audio's HD Series and XD Series amplifiers and many marine amps, allowing you to manage your level settings from the front of your vehicle. The HD-RLC adjusts your amplifier's level, not its "bass boost," so you maintain the same bass quality as you turn the volume up and down.

The HD-RLC remote level controller works with JL Audio's HD Series and XD Series amplifiers and many marine amps, allowing you to manage your level settings from the front of your vehicle. The HD-RLC adjusts your amplifier's level, not its "bass boost," so you maintain the same bass quality as you turn the volume up and down.

It works equally well with subwoofer and full-range amplifiers, and you can control multiple amplifiers with just one remote by adding standard phone cable splitter (not included). When used with the HD600/4 4-channel amplifier, you can assign it to control all channels, or the rear channels only.

Product Highlights:

  • remote level controller for JL Audio HD series amplifiers
  • rear or full-range channel assignment with HD600/4 4-channel amp
  • multi-amp capable (standard phone cable splitter required — not included)
  • warranty: 1 year
  • Our 60-day money-back guarantee

What's in the Box:

  • Remote level control knob with attached 9" cord terminated by a female RJ-11 plug
  • 18' Cord terminated by a male RJ-11 connector on each end
  • 2 Flat washers
  • 2 Nuts

A definite must-have!! Price seems high for what you're getting, but for what it does, that makes it worth it. I do wish the JL mono M600/1 included this, but unfortunately does not.

Overview: The JL Audio HD-RLC Remote Level Control is compatible with JL Audio HD and MHD series amplifiers. The HD-RLC attenuates the level of JL Audio HD and MHD amplifiers equipped with a Remote Level Control connector. The HD-RLC can be used as a true subwoofer level control or as a master volume control. Multiple amplifiers can be controlled with one HD-RLC by adding a standard phone cable splitter (sold separately).

Note: The HD-RLC is not compatible with JL Audio amplifiers which feature a Remote Bass Port. In this case you would need the JL Audio RBC-1 controller, sold separately.

Good reviews [ David  May 21, 2016 ]
The idea of having a simple knob to control the intensity of my subwoofers instantly caught my attention. With one amp per sub(s) and one remote per amp, i could control the level of, say, two 10s, an 8, and a 13.5, all to varying degrees, right from my drivers seat! Great invention! [ Christopher  May 18, 2016 ]
I like that I can control the bass weather its for more or less right at my front seat [ John  May 13, 2016 ]
My amp will not be easily accessible once installed. (Removing the passenger seat to make adjustments just isn't practical!) [ Robert  Apr 19, 2016 ]
Nice acc. to go with the amp [ Jeremy  Mar 14, 2016 ]
Makes level adjustments super easy with no fuss. Crutchfield service and quality is always awesome. [ Tom  Mar 05, 2016 ]
It controls the JL HD Amps. [ Clifford  Feb 29, 2016 ]
Perfect for adjusting amp level from the drivers seat. [ Robert  Feb 10, 2016 ]
to have control of the sub woofer at my finger tips for when my son is with me [ rodney  Feb 10, 2016 ]
The HD-RLC will allow me to turn off the subwoofer channel quickly without the need of going through the menu of the headunit. [ Richard  Jan 29, 2016 ]
This product works as designed well. However, you really don't need it if you have a SW control on your head unit or unless your running so much bottom end you can't control it through the head unit. [ JAMES A  Jan 27, 2016 ]

Hey Chris. This only controls the level of your sub. The gain is controlled by the tiny dial located on the amplifier's control panel. If you are able to find a "sweet spot" where the sub sounds good for most of your music, you should be able to leave it at that setting without adjusting it again. Good luck! [ chris  Jun 21, 2018 ]
This is actually a gain control. It can be bad if not set up correctly. [ JAMES  Jun 20, 2018 ]
Your gain is still set on the amp itself. You can't go past the level set on the amp. You can however turn the sub channel or all channels down and up volume wise from this control, but not exceeding output gain originally set when tuning the amp. [ Jared  Jun 20, 2018 ]
This remote will only work with certain jl audio amps and what it does is control the subwoofer volume . Xd and hd series I have an xd series subwoofer amp and that is what I use it for. Most jl audio amps that have a dedicated subwoofer channel will have a jack for sub level control. Hope this helps. [ CLAUS I  Jul 28, 2014 ]
Im sure it will if the amp is designed to receive this remote [ ROD  Jul 28, 2014 ]
This remote is for JL Audio amps only. Ho many channels it will control depends on the model of amplifier you have. On my 6 channel amp, there is a switch on the amplifier that sets the remote level control for either 2, 4, or all 6 channels. Check the instructions for your JL Audio amp. [ JEFF A  Jul 26, 2014 ]
I am not positive. I would assume so. I use mine for my mono amp for my sub. But I will say it works great! Very convenient [ JEREL  Jul 26, 2014 ]
Yes it works on 2 or 4 channel and mono amps as well. Just make sure you get the right remote for your series amp. JL makes 2 different ones. [ CAMERON  Jul 26, 2014 ]
So this can be a used as a bass boost remote. controling only the woofers, or can be used a volume for all channels. I don't use a head unit, so I use this as a master volume. [ CHRIS  Jul 26, 2014 ]
Only work with 5 channel amp [ MARIO  Jul 26, 2014 ]
