Frequently Asked Questions

Need help? Contact us

What type of power wiring is recommended for this amplifier?

For positive power (+12VDC) and ground (GND) connections, a 4 AWG cable is required. For the remote activation connection, a 18 to 12 AWG cable is sufficient.

Where should I install the protective fuse for the XDM600/1 amplifier?

A suitable 50A fuse must be installed on the positive power wire 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.

What are the accepted input voltage ranges for the amplifier?

The JL Audio XDM600/1 amplifier accepts an input voltage of 200 mV to 4 V RMS.

Can I connect a single subwoofer signal to the XDM600/1 amplifier?

Yes, if only one subwoofer channel signal is available, it is recommended to use a Y-adapter to power both inputs (CH. 1 and CH. 2) of the amplifier.

What are the purposes of the pre-amplified outputs (Preout) on the amplifier?

The pre-amplified outputs (Preout 1 and Preout 2) provide the same signal as the one connected to inputs CH. 1 and CH. 2. They are not affected by the amplifier's low-pass filter and can be used to feed the signal to another amplifier.

What type of electrical system is required for this amplifier?

This product must only be used with 12-volt negative-ground electrical systems. It is not certified or approved for use in aircraft.

What are the recommendations for amplifier placement?

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.

What do the different colors of the status LED indicate?

Green flashing: The amplifier is powered on, audio output is muted.Green solid: Normal operation, audio output active.Red solid: Safe mode, overheating condition, audio output reduced. The amplifier returns to normal operation when the temperature becomes safe again.Yellow solid: Safe mode, overcurrent condition, audio output muted. This may indicate a short circuit in the speaker/cable or low impedance.LEDs off: The amplifier is powered off (unexpectedly), low-voltage condition (when battery voltage or remote activation drops below 10V). It returns to normal operation when voltage exceeds 11V.

What are the different activation modes (Turn On Mode) of the amplifier?

The amplifier offers three activation modes:

Remote: Preferred activation via a switched +12V source or the activation output of your source/interface OEM unit.Offset (DC offset detection): Turns on by detecting a small DC signal in the OEM audio outputs and turns off after the signal is removed. Designed for high-level signals (speaker) only.Signal (signal detection): Turns on by detecting full-band OEM audio signals and turns off after the signal is removed (within 30 seconds).Using DC offset or signal detection methods converts the "Remote" terminal into a +12V activation output.

Is the XDM600/1 amplifier compatible with a remote level controller?

Yes, the amplifier is compatible with an optional remote level controller such as the HD-RLC or MHD-RLC. Multiple amplifiers can be controlled from a single HD-RLC using a non-duplex telephone line splitter and multiple telephone cables.

What is the minimum impedance supported by the subwoofer output?

The minimum impedance load supported by the subwoofer output is 2 ohms (≥2 ohms).

How should I route the cables during installation?

Route all system cables carefully away from moving parts and sharp edges. Secure them with cable ties or clamps and use grommets and sleeves where necessary to protect them from sharp edges.

Does the amplifier have an infrasonic filter?

Yes, the JL Audio XDM600/1 amplifier is equipped with an infrasonic filter. This filter attenuates frequencies below 30 Hz with a 24 dB/octave slope. It is designed to preserve amplifier power and protect the subwoofer from inaudible ultra-low frequencies that can cause excessive excursion.
