HD-RLC

The HD-RLC kit includes the rotary control with a black ABS knob, mounting hardware and one 18 ft. (5.5 m) cable.

A satin-finish aluminum knob can be purchased separately.

The HD-RLC remotely controls the Bass Level of the following JL Audio amplifiers:

• HD-Series: All models
• XD-Series: All models
• MHD-Series: All models
• M-Series: All models

When the HD-RLC is connected to the above amplifiers, it acts as an attenuator on the input gain of the amplifier and is used to adjust the overall level of the amplifier from the front of the vehicle.
