Detailed description

The JL Audio XDM800/8 marine amplifier is designed for marine and automotive sound systems, delivering a total RMS power of 800 watts across 8 channels. Featuring JL Audio’s NexD™ class D switching technology, it provides high energy efficiency with minimal distortion, enabling high output power in a compact chassis.

Audio performance and versatility

This amplifier delivers 75 watts RMS per channel at 4 ohms or 100 watts RMS per channel at 2 ohms at 14.4 V, with less than 1% THD. In bridged mode, it provides 200 watts RMS across 4 channels at 4 ohms. Its frequency response ranges from 12 Hz to 22 kHz (+0, -1 dB), and its signal-to-noise ratio exceeds 104 dB. RCA inputs accept a voltage range of 200 mV to 4 V RMS. Variable high-pass and low-pass filters (50–500 Hz, 12 dB/octave) are available for each pair of channels and can be bypassed for flexible configuration.

Robust marine design and integration

The JL Audio XDM800/8 features a marine-grade construction with corrosion-resistant materials, a black powder-coated finish, a sealed control cover, and stainless-steel hardware, ensuring protection against marine elements and corrosion. It includes a dual-mode input filter and balanced differential inputs for effective noise suppression. Automatic turn-on offers multiple options (signal detection, DC offset detection, or +12 V control wire) for simplified integration with existing systems. Signal-processing potentiometers are protected by a sealed security cover.

Expert opinion

« JL Audio XDM800/8: Power and modularity for marine sound »

The JL Audio XDM800/8 amplifier is an advanced marine audio solution, particularly suited to installations requiring multi-zone sound distribution or powerful amplification for complex systems. Its 8-channel full-range design offers remarkable flexibility, allowing simultaneous control of multiple speaker pairs (e.g., cockpit, cabin, foredeck) or configuration of more elaborate systems including one or more bridged subwoofers. The NexD™ Class D technology is a major asset, enabling the amplifier to deliver significant power without excessive heat generation—a critical factor in the confined spaces often found aboard boats. This efficiency results in a compact chassis, simplifying integration into tight mounting locations.

The marine-grade robustness of its construction, featuring a powder-coated finish and stainless-steel hardware, is essential for ensuring longevity against humidity, salt, and vibrations. The variable filter system and balanced differential inputs are important features for an engineer, as they allow precise sound tuning and excellent noise immunity—common challenges in marine environments. For installation, the flexible automatic power-on options simplify wiring to various audio sources, whether a main marine unit or an OEM system.

This amplifier is particularly relevant for boaters seeking a substantial improvement in their audio experience, with the ability to customize their sound setup. It is not intended for the simplest "plug and play" applications where a single low-channel amplifier would suffice, but rather for projects where sound quality, power, and integration flexibility are paramount.

Frequently Asked Questions

Need help? Contact us

What is the total output power of the JL Audio XDM800/8 amplifier?

The JL Audio XDM800/8 amplifier delivers a total power output of 800 watts, distributed across its 8 channels.

How many output channels does the XDM800/8 amplifier have?

The JL Audio XDM800/8 amplifier is an 8-channel model, allowing connection of multiple pairs of speakers or a combination of speakers and subwoofers.

Is the XDM800/8 amplifier specifically designed for marine use?

Yes, the JL Audio XDM800/8 amplifier is designed for marine and automotive sound systems, making it suitable for the demanding environments found on boats.

What does the steady green color of the status LED on the amplifier indicate?

When the status LED is solid green, this indicates normal operation of the amplifier with active audio output.

What audio filtering options are available on the XDM800/8?

The XDM800/8 amplifier offers several filtering options:

Off: The filter is disabled, allowing all frequencies present at the inputs to pass through.
HP (High-Pass): Attenuates frequencies below the "Filter Freq. (Hz)" dial setting at a rate of 12dB/octave.
LP (Low-Pass): Attenuates frequencies above the "Filter Freq. (Hz)" dial setting at a rate of 12dB/octave.

What is the purpose of the input sensitivity adjustment (Input Sens.)?

The input sensitivity adjustment (Input Sens.) is used to match the output voltage of your source unit (car stereo, etc.) to the inputs of each channel pair on the amplifier. This ensures optimal audio performance and prevents distortion.

Is there a remote level controller compatible with this amplifier?

Yes, a remote level controller is available as an option. The HD-RLC or MHD-RLC models are compatible. It functions like an attenuator: fully turned counterclockwise, the level is cut; fully turned clockwise, the level is unaffected.

What is the required operating voltage for the JL Audio XDM800/8 amplifier?

The JL Audio XDM800/8 amplifier is designed to operate only with 12-volt negative-ground electrical systems.

What are the recommended and prohibited installation locations for the XDM800/8 amplifier?

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

What gauge wire is required for the positive and negative power supply of the amplifier?

For the positive power supply (+12 VDC) and ground connection (GND), a 4 AWG (American Wire Gauge) wire is required for the XDM800/8 amplifier.

What is the required main fuse rating and where should it be installed?

A suitable 80A fuse is critical for safety and must be installed on the main positive power feed. It must be placed within 45 cm (18 inches) of the battery’s positive terminal. For ABYC and NMEA applications, circuit protection is required within 18 cm (7 inches) of the battery unless the cable is enclosed in a housing or conduit.

What essential safety precautions should I take before installing the amplifier?

Before installation, it is imperative to turn off the audio system and disconnect the battery from the audio system. Also ensure there are no obstacles behind the mounting surfaces before cutting or drilling.

How to protect system cables during installation?

It is important to route all system cables carefully, away from moving parts and sharp edges. Use cable ties or wire clamps to secure them, and use grommets and sleeves where appropriate to protect them from sharp edges.

Should the battery be disconnected from the audio system before installation?

Yes, it is imperative to disconnect the battery from the audio system before starting installation of the amplifier for safety reasons.

Is professional installation recommended for this amplifier?

Yes, installing this amplifier requires appropriate tools and safety equipment. Professional installation is recommended to ensure correct and secure setup.

What are the minimum impedances for speakers in stereo mode?

In stereo mode, the JL Audio XDM800/8 amplifier supports a minimum load impedance of 2 ohms per channel.

What are the minimum impedances for speakers in bridged mode?

In bridged mode, the JL Audio XDM800/8 amplifier supports a minimum load impedance of 4 ohms.

Is the XDM800/8 amplifier compatible with automotive electrical systems?

Yes, the JL Audio XDM800/8 amplifier is designed to be compatible with automotive electrical systems in addition to marine systems. It operates with 12-volt negative-ground systems.
