speaKer output

Subwoofer connection to the JX monoblock
is straightforward and takes place at the
far right of the power/speaker connection
panel. Two positive ("+") connections and
two negative ("–") connections are available
via a connector labeled "Speaker Output
(Mono)". The dual connections allow for two
separate speaker wire runs to be parallel-
connected to the amplifier's mono output.

I m p o r ta n t !
Speaker loads below 2Ω nominal are not
recommended and will cause the amplifier to
enter into a protection mode.
Do not chassis ground any speakers connected
to this or any other JL Audio amplifier. Doing so
will cause the amplifier to go into protection.
To connect the speaker wires to the amplifier,
strip 1/2-inch (12 mm) of insulation from each
speaker wire and insert them into their
appropriate connector (observing correct
polarity). Then, tighten each connector using the
supplied 2.5 mm hex wrench.

Do NOT attempt to "bridge" two JX
monoblocks together or combine their output
to a single load in any manner. Doing so will
damage the amplifier(s).

Before reconnecting the battery ground and
turning the system on, verify that all control
settings on the amplifier are set according to
the needs of the system.

status IndIcator lIgHts /
protectIon cIrcuItrY
There are two status indicator lights on the
amplifier's control panel. These are as follows:
1) "Power" (Green): Located at the far left of the
amplifier's control panel, this LED lights to
indicate that the amplifier is turned on and
operating normally.
2) "Protect" (Red): Indicates that the amplifier
protection circuitry has been activated
to prevent product failure due to thermal
overload, short-circuit or a dangerously
low impedance connected to the amplifier
outputs. Connecting the speaker output to
an impedance lower than 2 ohms will cause
this protection mode to activate. When this
protection mode is activated, the amplifier will
shut down to protect its circuitry. When the
problem is corrected, the amplifier will return
to normal operation and the "Protect" LED
will shut off.

serVIcIng Your amplIFIer

If your amplifier fails or malfunctions, please
return it to your authorized JL Audio dealer so
that it may be sent in to JL Audio for service.
There are no user serviceable parts or fuses inside
the amplifier. The unique nature of the circuitry
in the JL Audio amplifiers requires specifically
trained service personnel. Do not attempt
to service the amplifier yourself or through
unauthorized repair facilities. This will not only
void the warranty, but may result in the creation
of more problems within the amplifier.
If you have any questions about the installation or
setup of the amplifier not covered in this manual,
please contact your dealer or technical support.
