Marine amplifier XDM1000/1

The JL Audio XDM1000/1 amplifier is a Class D monoblock amplifier specifically designed to power subwoofers. It delivers an output power of 1000 watts.

Yes, the XDM1000/1 amplifier is a marine-grade model, designed to withstand the demanding conditions of a marine environment, while also being suitable for automotive use.

The infrasonic filter is designed to protect the subwoofer from inaudible ultra-low frequencies that could overload and potentially damage it. It also helps preserve amplifier power by avoiding the reproduction of these unnecessary frequencies.

The amplifier has three activation modes:

Remote: Activation via a switched +12V signal, typically from the source unit. This is the preferred method.
DC Offset-Sensing: Automatic activation by detecting a small DC signal in the OEM audio outputs (designed for high-level/speaker signals only).
Signal-Sensing: Automatic activation by detecting full-range OEM audio signals.
When DC Offset or Signal-Sensing modes are used, the amplifier's "Remote" terminal becomes a +12V output to activate other devices.

Yes, the XDM1000/1 amplifier has a dedicated connection for an optional remote level controller, such as the HD-RLC or MHD-RLC. This controller functions as a level attenuator, allowing remote adjustment of the subwoofer volume.

The status LED indicates the amplifier's operating state:

Flashing green: The amplifier is starting up; the audio output is muted.Fixed green: Normal operation; audio output is active.Fixed red: Safety mode activated due to overheating. Audio output is reduced. The amplifier will return to normal operation once the temperature is safe.Fixed amber (yellow): Safety mode activated due to overcurrent. Audio output is muted. This may indicate a short circuit in the speaker/wiring or an impedance that is too low.Off: The amplifier is off due to a low-voltage condition (battery voltage or "remote" terminal voltage below 10V). It will turn back on when the voltage exceeds 11V.

The XDM1000/1 amplifier is equipped with preamplified outputs ("Preout 1" and "Preout 2") that provide a "pass-through" signal. This means the input signal connected to inputs CH. 1 and CH. 2 is directly transmitted to these outputs without being affected by the amplifier's low-pass filter. This allows the signal to be chained to other amplifiers.

Yes, the JL Audio XDM1000/1 amplifier is a monoblock amplifier, meaning it is designed to power a single channel, typically a subwoofer, with high output.

A 4 AWG gauge wire is required for the positive power supply (+12 VDC) and ground (GND) connections of the XDM1000/1 amplifier.

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

The XDM1000/1 amplifier supports a minimum load impedance of ≥2 ohms for subwoofers. It is critical to respect this specification to avoid damaging the amplifier.

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

Before any installation, ensure you have the appropriate tools and safety equipment. It is recommended to consult a professional. Turn off the audio system and disconnect the battery from the audio system. Before cutting or drilling, check that there are no obstacles behind the mounting surfaces. Route all cables carefully away from moving parts and sharp edges, securing them with cable ties or clamps and using grommets and sleeves as needed.

For subwoofer connections, the XDM1000/1 amplifier is designed to accept wires from 16 to 8 AWG.

The "Input Filter" setting depends on your installation:

Car: Select this mode for most installations (automotive or marine). Boat: Select this mode if you experience interference from high-current mechanical switches/devices. Off: The filter is disabled.

No, the JL Audio XDM1000/1 product is not certified or approved for use in aircraft. It is designed for 12-volt negative-ground electrical systems in vehicles and boats.

The XDM1000/1 amplifier accepts RCA input signals with an input voltage ranging from 200 mV to 4 V. If only a single subwoofer channel signal is available, using a Y-adapter is recommended to power both inputs.

Yes, the amplifier can be integrated into OEM (original equipment manufacturer) audio systems thanks to its "DC Offset-Sensing" or "Signal-Sensing" activation modes, which detect the presence of audio signals to automatically power on the amplifier. The "DC Offset-Sensing" mode is specifically designed for high-level signals (speaker).

Yes, it is possible to control multiple JL Audio amplifiers (compatible with HD-RLC/MHD-RLC) from a single remote level controller using a non-duplex telephone line splitter and multiple telephone cables.

To ensure proper operation and longevity of the XDM1000/1 amplifier, it must be used exclusively with 12-volt negative-ground electrical systems. Professional installation is recommended, following the specified wire gauges and installing an appropriate fuse. Avoid overloads by adhering to the minimum 2-ohm impedance and ensure adequate ventilation to prevent overheating.
