JL Audio HD-RLC is a remote level control for JL Audio HD, XD, MHD and M series car amplifiers. It lets you reduce the connected amplifier’s overall level from the front of the vehicle. The package includes a rotary control with a black ABS plastic knob, mounting hardware and one 18 ft (5.5 m) cable. A satin-finish aluminium knob is sold separately.
JL Audio HD-RLC Level Control lets you adjust the overall level of a compatible car amplifier from the front of the vehicle. It attenuates the amplifier’s input gain, giving you a conveniently placed rotary control when a recording calls for a lower level or you want to turn down the part of the system that amplifier powers.
Which amplifiers is it for?
The HD-RLC is intended for all models in the JL Audio HD, XD, MHD and M amplifier series. It is an accessory for a car audio system in which you want a separate control for an amplifier’s level. Check the amplifier’s series first: the JL Audio name alone does not establish whether this accessory is suitable.
Find the exact model of the amplifier you own or plan to install. If it belongs to one of the listed series, consider whether adjusting its level from the front of the cabin would be useful. Other series are outside the compatibility list given here. Also consider what that amplifier powers, because the control changes the amplifier’s overall level rather than selecting a particular type of speaker.
What does the control change?
The rotary control changes the overall level of the connected amplifier. It can be used in a system with a subwoofer, but its function is not defined as bass-only adjustment. If the amplifier powers another part of the audio system, the purpose of the control remains the same: it changes the level of that amplifier.
Set the amplifier’s initial level while tuning the system. You can then use the HD-RLC to reduce that level to suit the recording or your preferred listening volume. Because it works by attenuating input gain, the remote control does not replace the amplifier’s initial setup. It is also not a separate tone or frequency control.
When setting up the system, treat these as two steps: adjust the amplifier itself first, then choose a comfortable position for the remote knob during everyday listening. Turn the knob gradually and listen to the part of the system powered by that amplifier. If the overall balance still needs changing after setup, review the amplifier’s settings instead of using the remote knob to compensate for an unsuitable initial level.
Positioning and connection
Plan a control position near the front of the vehicle, where you can comfortably reach the knob while seated. The package includes one 18 ft (5.5 m) cable and mounting hardware. Before mounting the control, work out the cable’s actual route through the vehicle’s trim to the amplifier. The length needed depends on where the equipment is installed.
Choose the cabin position with your normal seating position in mind, and plan the cable route around the amplifier’s real mounting location. A straight line between those points may be shorter than the route available inside the vehicle. Before fastening the control, check that the knob is easy to reach, the supplied cable reaches the amplifier along the planned route, and the included hardware suits your chosen mounting position.
The supplied cable is for connecting this control to a compatible amplifier. Use the exact amplifier model and its connection instructions when planning the installation. This description does not specify a connector type or the use of additional cables. For a new system, it helps to decide on the amplifier position, control position and complete cable route together before mounting any of them.
How it fits different systems
In a car stereo system, the HD-RLC is useful when you want the overall level of a compatible amplifier within reach at the front of the cabin. If that amplifier powers a subwoofer, you will hear the change in the bass produced by that part of the system. If it powers other speakers, their level will change instead. Decide which amplifier you want to control before buying; the speaker type by itself does not determine the accessory’s role.
If your vehicle has several amplifiers, note the series and role of each one. You can then decide which amplifier’s level you want to adjust from the front. The available information does not establish whether one HD-RLC can be connected to multiple amplifiers, so consult the instructions for the specific amplifiers before planning such a connection. This accessory is described for car audio systems; no home cinema compatibility information is provided.
Control and supplied parts
The supplied rotary control has a black ABS plastic knob. You will handle and see the knob when adjusting the level, so its appearance may matter when choosing a visible mounting position. A satin-finish aluminium knob is available separately; it is not included in this package.

FAQ
Does this control adjust only the bass?
No. It adjusts the overall level of the connected amplifier. If that amplifier powers a subwoofer, you will hear the level change in that part of the system.
Can the control replace the amplifier’s initial setup?
No. Set up the amplifier first, then use the knob to reduce its level while listening. The control attenuates input gain.
What if the cable does not reach the amplifier along the planned route?
Measure the full cable route before mounting the control. One 18 ft (5.5 m) cable is included. If it is too short, choose another mounting position or discuss the connection with an installer before buying.
Is this accessory suitable for a car stereo system?
Yes, if its amplifier belongs to one of the listed series. The control changes that amplifier’s level, so its effect depends on the amplifier’s role in the system.
Will the HD-RLC work with a JL Audio amplifier from another series?
Only the HD, XD, MHD and M series are listed as compatible here. If your amplifier belongs to another series, check the documentation for its exact model before choosing this accessory.
