JL Audio MHD-RLC Amplifier Remote Level Control and Cable, For JL Audio MHD and XDM Amplifiers, Water-Resistant, 16.4 ft Cable

Overview

The Garmin 010-13839-00 is a JL Audio water-resistant amplifier remote level control and cable for adjusting bass level from a more convenient location on board. It is used with compatible JL Audio amplifiers, including MHD and XDM models, and works as an attenuator on the amplifier input gain so the overall amplifier level can be adjusted without reaching the amp itself.

This is a practical add-on for marine audio systems where the amplifier is mounted out of sight in a console, locker, cabin space, or protected equipment area. The included 16.4' (5 m) cable gives installers room to place the control where the operator or passenger can reach it, such as near the helm or cockpit audio controls.

Key features

• Remote bass level control for compatible JL Audio amplifiers, including MHD and XDM models.
• Acts on the amplifier input gain as an attenuator, making level changes simple from the control location.
• Water-resistant control suited to exposed marine audio areas where spray and damp hands are part of normal use.
• Includes a black ABS knob for a clean control point at the helm, console, or dash area.
• Supplied with a 16.4' (5 m) cable to support flexible routing between the amplifier and control location.
• Mounting hardware is included for a straightforward installation.

Installation and setup

The control is best mounted where it can be reached easily while the boat is underway, without placing it where it will be kicked, snagged, or constantly washed down. The cable should be routed with the rest of the audio wiring where practical, keeping it protected from sharp edges, moving gear, and high-heat areas.

Because the control adjusts the amplifier level remotely, it is especially useful when the amplifier is installed behind panels or inside storage spaces. After installation, set the amplifier gain correctly first, then use this remote for day-to-day bass level changes at the helm or listening area.

Compatibility and use on board

This remote level control is intended for compatible JL Audio amplifiers and should be matched to the amplifier series before installation. It is a good fit for boats where bass output needs quick adjustment as passengers move around, engine noise changes, or music volume shifts between dockside use and cruising.

For marine systems with subwoofers or dedicated low-frequency channels, this control gives the operator a simple way to trim bass without changing the main source unit settings. That helps keep the system comfortable at low volume and better balanced when the boat is running.
