The XDM400/4 provides 75 watts RMS x 4 channels at 4 ohms or 100 watts RMS x 4 channels at 2 ohms at 14.4V, with total harmonic distortion (THD+N) below 1% at 2 ohms per channel. In bridged mode, it delivers 200 watts RMS x 2 channels at 4 ohms. Its signal-to-noise ratio exceeds 104 dB at rated power (A-weighted) and exceeds 84 dB (A-weighted) at 1 W. It features an RCA input sensitivity of 200 mV to 4 V RMS.

Integration and Durability

This model includes variable active high-pass and low-pass filters with adjustable cutoff frequency from 50 to 500 Hz and a slope of 12 dB/octave. Connectivity is optimized with balanced differential inputs, reducing noise induced by cables. The chassis is weather-resistant with a black powder-coated finish, a sealed control cover, and stainless-steel hardware, ensuring durability in demanding marine environments. The amplifier features advanced thermal rollback protection, adjusting output power to prevent shutdowns in case of overheating. It is compatible with optional remote level controllers HD-RLC or MHD-RLC. For power, a 40 A fuse (AFS, AGU, or MaxiFuse™) is required, with minimum 4 AWG wiring for power and ground. Dimensions are 216 mm (width) x 52 mm (height) x 180 mm (depth).

Expert opinion

« Technical analysis: JL Audio XDM400/4, marine performance and durability »

The JL Audio XDM400/4 amplifier stands out for its versatility and robust design, making it suitable for reliable integration in marine or automotive environments. Its NexD™ Class D technology delivers 400 watts RMS in a compact format, a major advantage for installations where space is limited without compromising audio quality.

In terms of installation, the advanced thermal management (Advanced Rollback Protection) prevents unexpected shutdowns, a critical feature at sea. The balanced differential inputs are particularly relevant for minimizing interference and electrical noise, common on boats. It is essential to adhere to the wiring gauge (4 AWG minimum for power and ground) and the fuse location (less than 45 cm from the battery, or 18 cm for ABYC/NMEA standards) to ensure system safety and performance. Its ability to accept high-level signals (speaker-level inputs) and provide preamplified outputs simplifies integration into existing or scalable systems.

This model is a sound choice for cockpit or cabin audio, providing a solid foundation for a high-quality audio system without requiring complex installation thanks to its flexible configuration options (4 satellite channels, 3 channels with subwoofer, or 2 channels).

Frequently Asked Questions

Need help? Contact us

What is the output power of the JL Audio XDM400/4 amplifier?

The JL Audio XDM400/4 amplifier is a 4-channel model delivering a total power output of 400 watts.

Is the XDM400/4 amplifier designed specifically for marine use?

Yes, the JL Audio XDM400/4 amplifier is specifically designed for marine applications, offering robustness and compactness suited to this environment.

What are the main specifications of the JL Audio XDM400/4 amplifier?

The JL Audio XDM400/4 amplifier is a full-range 4-channel marine amplifier delivering 400 watts of power. It is designed to be robust and compact.

What does the status LED on the XDM400/4 amplifier indicate?

A green LED indicates normal operation with active audio output. A red LED signals a safety mode due to overheating, with reduced audio output. An orange (amber) LED indicates a safety mode due to overcurrent, a speaker/wire short circuit, or low impedance, with audio output cut off. If the LEDs are off, this may indicate a low-voltage condition (below 10V), causing the amplifier to shut down.

Is the XDM400/4 amplifier a full-spectrum model?

Yes, the JL Audio XDM400/4 amplifier is a full-range marine amplifier with 4 channels.

What filtering options are available on the XDM400/4 amplifier?

The XDM400/4 amplifier offers configurable filtering modes for each pair of channels (CH. 1&2 and CH. 3&4). You can select between:

Off: The filter is disabled, allowing the full frequency range to pass through.HP (High-Pass): Attenuates frequencies below the defined cutoff frequency.LP (Low-Pass): Attenuates frequencies above the defined cutoff frequency.The cutoff frequency is adjustable from 50 Hz to 500 Hz with a 12 dB per octave slope.

What are the important safety considerations before installing the XDM400/4 amplifier?

Use this product only with 12-volt negative-ground electrical systems.Mount the amplifier securely to prevent damage or injury in harsh conditions.A suitable fuse (or circuit breaker) on the main power lead is essential for safety and must be installed within 45 cm (18 in) of the battery’s positive terminal.For ABYC and NMEA applications, circuit protection is required within 18 cm (7 in) of the battery unless the cable is enclosed in a housing or conduit.

Where is the best place to install the JL Audio XDM400/4 amplifier?

The amplifier should be installed in a dry, well-ventilated location that does not interfere with factory-installed systems. Avoid the engine compartment, areas of extreme heat, or locations directly exposed to the elements.

Which type of wiring is recommended for powering the XDM400/4 amplifier?

For the positive power connection (+12VDC) and ground connection (GND), a 4 AWG wire is required (minimum 8 AWG for +12VDC). A 40A fuse must be installed at the battery's positive terminal.

Should the boat's battery be disconnected before installing the amplifier?

Yes, before any installation, it is essential to power off the audio system and disconnect the battery system from the audio system for safety reasons.

How to manage wiring when installing the amplifier?

Route all system wiring carefully away from moving parts and sharp edges. Secure it with cable ties or clamp bands and use grommets and sleeves where appropriate to protect wires from sharp edges.

Is professional installation recommended for this amplifier?

Yes, installing the JL Audio XDM400/4 amplifier requires appropriate tools and safety equipment, and professional installation is recommended.

What wire gauge is required for the XDM400/4 amplifier speaker outputs?

The XDM400/4 amplifier speaker outputs accept wires from 16 to 8 AWG.

What type of wire is required for the remote activation connection?

The remote activation connection requires an 18 to 12 AWG wire and a positive activation (+12V).

Is the XDM400/4 amplifier compatible with all boat electrical systems?

No, this amplifier is only compatible with 12-volt negative-ground electrical systems. It is not certified or approved for use in aircraft.
