JL Audio Water-Resistant Amplifier Remote Level Control and Cable (MHD-RLC) - 010-13839-00 (98121)

Overview

The JL Audio MHD-RLC is a water-resistant remote level controller designed specifically for JL Audio MHD and XDM Series amplifiers. Mounted up front, it lets you fine-tune overall amplifier output from the helm or driver’s seat without changing the amp’s base gain setup, making it ideal for high-end marine and automotive systems that need precise level control on the fly.

Key Features & Benefits

• Remote level controller for compatible JL Audio MHD and XDM Series amplifiers.
• Acts as an attenuator on the amplifier’s input gain, letting you turn system level up or down from the listening position.
• Supplied with a 16.4 ft (5 m) cable to reach from amp location to dash/helm or other convenient control point.
• Water-resistant design and hardware suitable for marine and other demanding environments.
• Multi-amp capable when used with a standard phone-cable style splitter (not included), allowing one control to manage multiple compatible amps.

Typical Applications

• Marine systems using JL MHD or XDM amplifiers where you want helm-mounted system level control.
• Automotive installs where amplifiers are mounted remotely (trunk, hatch, under seat) and front-seat level control is required.
• Multi-amp sub + full-range JL layouts where a single knob needs to manage overall output level.

What’s In The Box

• JL Audio MHD-RLC rotary remote level controller with knob.
• 16.4 ft (5 m) control cable.
