high-power amplifiers are capable of producing
such high sound pressure levels when connected

to a speaker system. Please limit your continuous

exposure to high volume levels.

While driving, operate your audio system in
a manner that still allows you to hear necessary
noises to operate your vehicle safely (horns,
sirens, etc.).

INSTALLATION APPLICATIONS

This amplifier is designed for operation in
vehicles with 12 volt, negative-ground electrical
systems. Use of this product in vehicles with
positive ground and/or voltages other than 12V
may result in damage to the product and will void
the warra nt y.

This product is not certified or approved for
use in aircraft.

Do not attempt to “ bridge” the outputs of this
amplifier with the outputs of a second amplifier,
including an identical one.

PLANNING YOUR INSTALLATION

It is important that you take the time to read
this manual and that you plan out your
installation carefully. The following are some
considerations that you must take into account
when planning your installation.

Cooling Efficiency Considerations:

The outer shell of your JL Audio amplifier is
designed to remove heat from the amplifier
circuitry. For optimum cooling performance, this
outer shell should be exposed to as large a volume
of air as possible. Enclosing the amplifier in a
small, poorly ventilated chamber can lead to
excessive heat build-up and degraded
performance. If an installation calls for an
enclosure around the amplifier, we recommend
that this enclosure be ventilated with the aid
of a fan. In normal applications, fan-cooling
is not necessary.

IMPORTANT!

Mounting the amplifier upside down is
strongly discouraged.

If mounting the amplifier under a seat,
make sure there is at least 1 inch (2.5 cm) of
space above the amplifier’s outer shell to permit
proper cooling.

Safety Considerations:

Your amplifier needs to be installed in a dry,
well-ventilated environment and in a manner
which does not interfere with your vehicle’s safety
equipment (air bags, seat belt systems, ABS brake
systems, etc.). You should also take the time to
securely mount the amplifier so that it does not
come loose in the event of a collision or a sudden
jolt to the vehicle.

Stupid Mistakes to Avoid

• Check before drilling any holes in your vehicle

to make sure that you will not be drilling
through a gas tank, brake line, wiring harness or
other vital vehicle system.

• Do not run system wiring outside or underneath

the vehicle. This is an extremely dangerous
practice which can result in severe damage to
your vehicle and person.

• Protect all system wires from sharp metal

edges and wear by carefully routing them,
tying them down and using grommets and
loom where appropriate.

• Do not mount the amplifier in the engine

compartment, under the vehicle, on the roof
or in any other area that will expose the
amplifier circuitry to the elements.

PRODUCT DESCRIPTION

The JL Audio JX360/2 is a two­channel, full-range audio amplifier
utilizing Class A/B technology.

The JX360/2 can be operated with a wide
variety of source units and system configurations.
For detailed specifications, please refer to
Appendix B (page 13).

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence
for a typical amplifier installation, using an
aftermarket source unit or OEM Interface
product. Additional steps and different
procedures may be required in some applications.
If you have any questions, please contact your
authorized JL Audio dealer for assistance.

1) Disconnect the negative battery post

connection and secure the disconnected cable
to prevent accidental re-connection during
installation. This step is not optional.

2) Run 4 AWG power wire from the battery

location to the amplifier mounting location,
taking care to route it in such a way that it
will not be damaged and will not interfere
with vehicle operation. Use 2 AWG or larger
power wire and a power distribution block if
additional amplifiers are being installed with
the JX360/2.

3) Connect power wire to the positive battery

post. Fuse the wire with an appropriate fuse
block (and connectors) within 18 inches (45
cm) wire length of the positive battery post.

This fuse is essential to protect the vehicle.
Do not install the fuse until the power wire
has been securely connected to the amplifier.

4) Run signal cables and remote turn-on wire

from the source unit to the final amplifier
mounting location.

5) Run speaker cables from the speaker systems
to the amplifier mounting location.

6) Find a good, solid metal grounding point
close to the amplifier and connect the
negative power wire to it using appropriate
hardware. Use the same size power wire as the
wire connected to the “+12V DC ” connection
(minimum 4 AWG), no longer than 36 inches
(90 cm) from the amplifier to the ground
connection point. In some vehicles, it may be
necessary to upgrade the battery ground wire.
(See page 5 for important notice).

7)

Securely mount the amplifier using
appropriate hardware.

8) Connect the positive and negative power
wires to the amplifier.

9) Connect the remote turn-on wire
to the amplifier.

10) Connect the input cables to the amplifier.

11) Connect the speaker cables to the amplifier.

12) Carefully review the amplifier’s control

settings to make sure that they are set
according to the needs of the system.

13) Install the power wire fuse (50A for a
single JX360/2) and reconnect the negative
battery post terminal.

14) Turn on the source unit at a low level
to double-check that the amplifier is
configured correctly. Resist the temptation
to crank it up until you have verified the
control settings.

15) Make necessary adjustments to the input
sensitivity controls to obtain the right
overall output and the desired balance
in the system. See Appendix A (page 12)
for the recommended input sensitivity
setting method.

16) Enjoy the fruits of your labor with your
favorite music.

POWER CONNECTIONS

Before installing the amplifier, disconnect the
negative (ground) wire from the vehicle’s battery.
This will prevent accidental damage to the system,
the vehicle and your body during installation.

+12 VDC Ground Remote

The JX360/2’s “+12VDC ” and “Ground”
connections are designed to accept 4 AWG power
wire. 4 AWG is a minimum power wire size for

this amplifier.

If you are installing the JX360/2 with other
amplifiers and wish to use a single main power
wire, use 2 AWG or larger main power wire
(depending on the overall current demands of all
the amplifiers in the system). This 2 AWG or
larger power wire should terminate into a fused
distribution block mounted as close to the
amplifiers as possible and should connect to the
JX360/2 with 4 AWG power wire.

Note: Smaller AWG numbers mean bigger wire
and vice-versa (1/0 AWG is the largest, 2 AWG is
smaller, then 4 AWG, then 8 AWG, etc.).

To connect the power and ground wires
to the amplifier, strip 1/2-inch (12 mm) of
insulation from each wire and insert the bare
wire into the the appropriate terminal block
positions on the JX360/2. Use the supplied

2.5 mm hex wrench to secure the wire via
the screw on the top of each terminal.

The “GROUND” connection should be made
using 4 AWG wire and should be kept as short
as possible, while accessing a solid piece of sheet
metal in the vehicle. The surface of the sheet
metal should be sanded at the contact point
to create a clean, metal-to-metal connection

between the chassis and the termination of the
ground wire. The use of a #10 sheet metal screw
and star washer to lock down the connection is
advisable. Alternatively, you can use a specialized
grounding lug, such as the JL Audio XB-MGLU.

Any wires run through metal barriers (such as
firewalls), must be protected with a high quality
insulating grommet to prevent damage to the
insulation of the wire. Failure to do so may result
in a dangerous short circuit.

IMPORTANT!

Many vehicles employ small (10 AWG -
6 AWG) wire to ground the battery to the
vehicle chassis and to connect the alternator’s
positive connection to the battery. To prevent
voltage drops, these wires should be upgraded
to 4 AWG when installing amplifier systems
with main fuse ratings above 60A.

FUSE REQUIREMENTS

An appropriate fuse at the main power wire(s)
to the amplifier(s) is vital for vehicle safety! This
fuse must be installed within 18 inches (45 cm)
of the positive battery post connection. If the
JX360/2 is the only device connected to this main
wire, use a 50A AGU or MAXI® fuse (no other
fuse is required in this situation).

When running multiple devices from one
main power wire, the main fuse value and rating
of the main power wire must be high enough
for all of the equipment being run from it. Use a
fused distribution block to split the main power
wire feed to each device, with appropriate fusing
and power wire for each device.

TURNON LEAD

CH. 1

(L)

CH. 2

(R)

Bridged

The JX360/2 is turned on and off

using a conventional +12V remote turn-

on lead, typically controlled by the
source unit’s remote turn-on output.

+12 VDC Ground Remote

The amplifier will turn on when +12V is

present at its “Remote” input and turn off when

+12V is switched off. If a source unit does not

have a dedicated remote turn-on output, the

amplifier’s turn-on lead can be connected to +12V

via a switch that derives power from an ignition­switched circuit.

18 AWG wire is more than adequate for the
remote turn-on connection. To connect the
remote turn-on wire to the amplifier, strip 1/2­inch (12 mm) of insulation from the wire and
insert it into the “Remote” receptacle on the
power connector. Tighten the connector down
using the supplied 2.5 mm hex wrench.

INPUT SECTIONS

The JX360/2’s has one pair of stereo
inputs.The input section input section
offers two input connection methods, one
for high-level (speaker level) signals and
one for low-level (preamp level) signals.

1) Low-Level Inputs: A standard left/

right pair of RCA type jacks in the
“Amplifier Inputs” section is used for
preamp level (low-level) signal input
on the JX360/2. This is the preferred
connection method whenever available.

INPUT SENSITIVITY CONTROL

2) Hi-Level Inputs: If your system does not offer
a preamp level signal option, you can connect
speaker level signals directly to the “Hi-Level
Inputs” connectors using the supplied mating
connectors and wire harnesses. Simply splice
the appropriate left/right and positive/negative
wires to the included harnesses and plug the
harness into the “Hi-Level Inputs” connectors
on the amplifier. The JX360/2 will attenuate

The control labeled “Input Sens.” can be used
to match the source unit’s output voltage to the
input stage the amplifier for maximum clean
output. Rotating the control clockwise will result
in higher sensitivity (louder for a given input
voltage). Rotating the control counter-clockwise
will result in lower sensitivity (quieter for a given
input voltage.)

ENGLISH

the high-level signals to make them compatible
with its input stage.

IMPORTANT!

Make sure you observe correct polarity in
making the “Hi-Level Input” connections.
Failure to do so will reduce bass and affect
stereo imaging.

The connections for the “Hi-Level Inputs” plug wires
are as follows from left to right on the plug:

Channel 1 (Left)

White: Left Positive (+)

White/Black: Left Negative (–)

Black: Common Ground (rarely used)*

To properly set the amplifier for maximum
clean output, please refer to Appendix A

Channel 2 (Right)

Gray: Right Positive (+)

Gray/Black: Right Negative (–)

*The only time you will use the Common Ground

(page 12) in this manual. After using this
procedure, you can then adjust the “Input
Sens.” level downward if this is required
to achieve the desired system balance.

connections is with some older (pre-1980’s) factory
systems or head units that ground their speakers to
chassis ground. To use these connections, ground
the black wires on the plugs to chassis ground and

only connect the Left and Right Positive plug wires

to the factory radio outputs.

IMPORTANT!

Do not increase any “Input Sens.” setting for
any channel(s) of any amplifier in the system
beyond the maximum level established during
the procedure outlined in Appendix A (page

12). Doing so will result in audible distortion
and possible speaker damage.

IMPORTANT!

When the amplifier is bridged, both the Left
and Right inputs must be fed with signal.
Failure to do so will result in significant
audible distortion.

See "Bridging Considerations" section on Page 10

for further information.

FILTER CONTROLS

The active filter built into the JX360/2 can
be used to eliminate potentially harmful and/
or undesired frequencies from making their way
through the amplifier section to the speaker(s).
This serves to improve tonal balance and to avoid
distortion and possible speaker failure. Correct
use of this filter can substantially increase the
longevity and fidelity of your audio system.

1) “Filter Mode” Control: The JX360/2 employs

a 12dB per octave filter. This filter can be
configured into one of two filter types or
defeated completely by way of the three­position “Filter Mode” switch:
“HP” (High-Pass): Configures the filter to
attenuate frequencies below the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of component speakers
the JX360/2’s in a bi-amplified system.
Of f”: Defeats the filter completely, allowing the
full range of frequencies present at the inputs
to feed the amplifier. This is useful for systems
utilizing outboard crossovers or requiring full­range reproduction from the JX360/2.
“LP” (Low-Pass): Configures the filter to
attenuate frequencies above the selected filter
frequency at a rate of 12dB per octave. This is
useful for connection of subwoofer(s) to the
JX360/2’s in a bi-amplified system.

2) “Filter Freq. (Hz)” A simple rotary control
adjusts the filter cutoff frequency of the filter
type you have selected with the “Filter Mode”
switch. This control will have no effect if you
have selected the “Off ” position for the “Filter
Mode”).

The filter in the JX360/2 is fully variable between
50 Hz and 200 Hz. The "80" Hz position is a
good starting point for tuning systems utilizing
typical subwoofers and component or coaxial
speakers.

PREOUTS

The JX360/2 incorporates a pass-through

preamp output (Preouts) section, so that

additional amplifiers can be easily added to
the system. This pass-through pre-amp output
delivers the same signals that are fed into the
amplifier's Low-Level inputs. Input signals
applied to the High-Level inputs will not pass

through the Preouts.

The preamp output signal is not affected by the
“Bass Boost” processing selected for the amplifier
or by any crossover filter selected (if the input
signal is full-range, the preamp output will be
fu ll-range).

Note: The signal level of the “Preouts” is always
line-level (low voltage).

SPEAKER OUTPUTS

!

!

!

The JX360/2’s speaker outputs are designed to

accept 16 AWG - 8 AWG wire.

Bridged

CH. 1

(L)

CH. 2

(R)

JX360/2 is designed to deliver power into
speaker loads equal to or greater than 2 ohms per
channel when using a “stereo” configuration and
speaker loads equal to or greater than 4 ohms
when using a “bridged” configuration.

IMPORTANT!

Speaker loads below 2 ohms nominal per
channel are not recommended and may cause
the amplifier to initiate a protection mode.

BRIDGING CONSIDERATIONS

Bridging is the practice of combining the
output of two amplifier channels to drive a single
load. When bridged, each channel produces
signals of equal magnitude, but opposite polarity.
The combined output of the two channels
provides twice the output voltage available from
a single channel. The JX360/2 has been designed
for bridging of its channels without the need for
input inversion adaptors.

To bridge a pair of channels, use the
“Left +” and “Right –” speaker connectors only
(the “Left –” and “Right +” remain unused).
When bridged, the amplifier will deliver
optimum power into a 4 ohm load.

IMPORTANT!

When bridged, the JX360/2 will deliver 360W
x 1 into a 4 ohm load or 220W x 1 into an 8
ohm load. Operating a pair of bridged
channels into a load lower than 4 ohms is
not recommended.

IMPORTANT!

Any bridged channel pair must be fed by both
Input Channels corresponding to it (Left and
Right). Failure to do so will result in significant
audible distortion.

When the JX360/2 is operating in bridged
mode, the output will be in mono (only one
channel). This mono channel can contain right
channel only information, left channel only
information or the sum of the information from
both the right and left channels. In order to
achieve one of these options, configure the inputs
to that pair of channels in one of these two ways:

1) Left Channel Only or Right Channel Only

Information: If you wish to send a left-only

or right-only signal to the JX360/2, use a
“Y-Adaptor” to split the single channel signal
into both left and right RCA inputs. This
option is useful when using the JX360/2 to
drive left channel speakers only and another
JX360/2 to drive right channel speakers only.

2) Left + Right Channel Information:

When bridged and fed by a stereo input, the
JX360/2 will automatically combine the left
and right input channels into a summed mono

(left + right) channel. This option is useful

when using a the JX360/2 to drive a subwoofer
system or a summed mono center channel.

AMPLIFIER STATUS INDICATOR LIGHTS &
PROTECTION CIRCUITRY

There are two status indicator lights on the

control panel of the amplifier.

1) “Power” (Green): lights to indicate that the
amplifier is turned on and operating normally.
Located at the far left of the control panel.

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 outputs
to an impedance lower than 2 ohms stereo
(4 ohms bridged) 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.

Input Sensitivity Level Setting

Following the directions below will allow the
installer to adjust the input sensitivity of each
amplifier channel pair simply and easily in just a
few minutes using equipment which is commonly
available in installation bays.

Necessary Equipment

• Digital AC Voltmeter

• CD with a sine-wave test tone recorded at

0 dB reference level in the frequency range
to be amplified for that set of channels
(50 Hz for subwoofer channels, 1 kHz for a
midrange application). Do not use attenuated
test tones (-10 dB, -20 dB, etc.).

The Nine-Step Procedure

1) Disconnect the speaker(s) from the

amplifier’s speaker output connectors (you need
only disconnect one wire on each output).

2) Turn off all processing (bass/treble, loudness,

EQ, etc.) on the source unit, processors (if
used) and amplifier. Set the source unit's fader
control to center position and its subwoofer level
control to 3/4 of maximum.

3) Turn the “Input Sens.” control all the

way down.

4) Set the source unit volume to 3/4 of full

volume. This will allow for reasonable gain
overlap with moderate clipping at full volume.

5) Using the chart on this page, determine the target

voltage for input sensitivity adjustment according
to the nominal impedance of the speaker system
connected to the amplifier outputs.

6) Verify that you have disconnected

the speakers before proceeding. Play

a track with an appropriate sine wave

(within the frequency range to be

amplified) at 3/4 source unit volume.

7) Connect the AC voltmeter to the speaker output

connectors of the amplifier. Make sure you test

the voltage at the correct connectors (+ and –).

8) Increase the “Input Sens.” control until the

target voltage is observed with the voltmeter.

9) Once you have adjusted the amplifier to
its maximum low-distortion output level,
reconnect the speaker(s) and listen to the
system. The “Input Sens.” controls can
now be adjusted downward if the amplifier
requires attenuation to achieve the desired
system balance.

IMPORTANT!

Do not increase any “Input Sens.” setting for
any amplifier channel or channel pair in the
system beyond the maximum level established
during this procedure. Doing so will result in
audible distortion and possible speaker damage.

It will be necessary to re-adjust the
“Input Sens.” for the affected channels if any
equalizer boost is activated after setting the
“Input Sens.” with this procedure. This applies
to any EQ boost circuit, including source unit
tone controls or EQ circuits. EQ cuts will not
require re-adjustment.

APPENDIX C: TROUBLESHOOTING
“How do I properly set the input sensitivity on my amplifier”

Please refer to Appeaset the input sensitivity for maximum, low-

distortion output.

“My amplifier doesn’t turn on”

Check the fuse, not just visually, but with a continuity meter. It is

possible for a fuse to have poor internal connections that
cannot be found by visual inspection. It is best to take the
fuse out of the holder for testing. If no problem is found with
the fuse, inspect the fuse-holder.

Check the integrity of the connections made to each of the

“+12VDC ”, “Ground”, and “Remote” terminals. Ensure
that no wire insulation is pinched by the terminal set screw
and that each connection is tight.

Check to make sure there is +12V at the “Remote” connection of the

amplifier. In some cases, the turn-on lead from the source unit
is insufficient to turn on multiple devices and the use of a relay
is required. To test for this problem, jump the “+12V DC” wire
to the “Remote” terminal to see if the amplifier turns on. If this
does not work, proceed to the next step.

“My amplifier’s output fluctuates when I tap on it or hit a bump”

Check the connections to the amplifier. Make sure that the

insulation for all wires has been stripped back far enough to
allow a good contact area inside the terminal block.

Check the input connectors to ensure that they all are making good

contact with the input jacks on the amplifier.

“My amplifier turns on, but there is no output”

Check the input signal using an AC voltmeter to measure the

voltage from the source unit while an appropriate test tone is
played through the source unit (disconnect the input cables
from the amplifier prior to this test). The frequency used
should be in the range that is to be amplified by the amplifier
(example: 50 Hz for a sub bass application or 1 kHz for a full
range / high-pass application). A steady, sufficient voltage
(between 0.2 and 8.0-volts) should be present at the output of
the signal cables.

Check the output of the amplifier. Using the procedure explained in

the previous check item (after plugging the input cables back
into the amplifier) test for output at the speaker outputs of
the amplifier. Unless you enjoy test tones at high levels, it is
a good idea to remove the speaker wires from the amplifier
while doing this. Turn the volume up approximately half
way. 5V or more should be measured at the speaker outputs.
This output level can vary greatly between amplifiers but it
should not be in the millivolt range with the source unit at
half volume. If you are reading sufficient voltage, check your
speaker connections as explained below.

Check to ensure that the speaker wires are making a good

connection with the metal inside the terminal block. The
speaker wire connectors are designed to accept up to 8 AWG
wire. Make sure to strip the wire to allow for a sufficient
connection with the metal inside the terminal block.

PLANIFICACIÓN DE LA INSTALACIÓN

Es importante que dedique tiempo a leer
este manual y que planifique cuidadosamente
lainstalación. A continuación se indican algunas
consideraciones que debe tener en cuenta
alplanificar la instalación.

Consideraciones relativas a la eficiencia
deenfriamiento:

La carcasa externa de su amplificador JL Audio
se ha diseñado para eliminar el calor del circuito

del amplificador. Para lograr el rendimiento

de enfriamiento óptimo, la carcasa debe estar
expuesta al mayor volumen de aire posible.
Si el amplificador se coloca en una cámara
pequeña con escasa ventilación, se producirá una
acumulación de calor excesiva y se degradará
el rendimiento. Si la instalación requiere un
espacio envuelto alrededor del amplificador,
recomendamos que este se ventile con la ayuda

de un ventilador. Para aplicaciones normales,

nose requiere enfriamiento con un ventilador.

IMPORTANTE

!

Se desalienta firmemente montar
elamplificador boca abajo.

Si se monta el amplificador debajo
deunasiento, asegúrese de que haya por
lomenos 2,5 cm (1 pulgada) por encima
delacarcasa del amplificador para permitir
unenfriamiento adecuado.

Consideraciones relativas a la seguridad:

El amplificador se debe instalar en unlugar
seco y bien ventilado, y de manera que
nointerfiera con los equipos de seguridad del
vehículo (bolsas de aire, sistemas decinturones
de seguridad, sistemas de frenos ABS, etc.)
Debe dedicar tiempo a montar el amplificador
de manera segura a fin de que no se suelte
siseproduce un choque o el vehículo
daunsaltorepentino.

Errores sencillos que debe evitar

• Antes de perforar un agujero en el vehículo,

compruebe que no perforará el tanque de
gasolina, la línea de frenos, el arnés de cableado
u otro sistema esencial del vehículo.

• No instale el cableado en el exterior o debajo

del vehículo. Es una práctica extremadamente
peligrosa que puede provocar daños graves
asuvehículo y a usted mismo.

• Proteja todos los cables del sistema de bordes

metálicos afilados y desgaste. A tal fin,
colóquelos cuidadosamente, amárrelos y use
ojales y organizadores de cables donde sea
apropiado.

• No instale el amplificador en el compartimento

del motor, debajo del vehículo, sobre el techo
nien ninguna otra zona en la que el circuito del
amplificador esté expuesto a los elementos.

DESCRIPCIÓN DEL PRODUCTO

El JL Audio JX360/2 es un amplificador
de rango completo y de dos canales
que utiliza tecnología Clase A/B.

El JX360/2 puede funcionar con una amplia
variedad de unidades fuente y configuraciones

de sistema. Para conocer las especificaciones

detalladas, consulte el Apéndice B (página13).

SECUENCIA DE INSTALACIÓN TÍPICA

A continuación se representan los pasos
necesarios para la instalación típica de un
amplificador mediante el uso de un reproductor
de audio posventa o una interfaz con equipo
de fábrica. En algunos casos, pueden requerirse
pasos adicionales y procedimientos diferentes.
Sitiene cualquier duda, póngase en contacto con
un concesionario autorizado de JL Audio para
solicitar asistencia.

1) Desconecte la conexión del polo
negativo de la batería y sujete el cable
desconectadopara evitar una reconexión
accidental durante la instalación. Este paso

no es opcional.

2) Lleve el cable de alimentación calibre

4AWG desde la ubicación de la batería
hasta el lugar de montaje del amplificador,
con cuidado de colocar el cable de
manera que no se dañe ointerfiera
con el funcionamiento del vehículo. Si
desea instalar amplificadores adicionales
junto con el JX360/2, use un cable
dealimentación calibre 2 AWG o más
grueso yun bloque de distribución
dealimentación.

3) Conecte el cable de alimentación al polo
positivo de la batería. Interrumpa el cable
con un bloque de fusibles apropiado
(yconectores) a 45 cm (18 pulgadas) como
máximo del polo positivo de la batería.

Este fusible es esencial para proteger
el vehículo. No instale el fusible hasta
que elcable de alimentación se haya
conectado al amplificador.

4) Lleve los cables de señal y el cable

deencendido remoto desde la unidad
fuente hasta el lugar de montaje final
delamplificador.

5) Lleve los cables de los altavoces desde
el sistema de altavoces hasta el lugar
demontaje del amplificador.

6) Escoja un punto de toma a tierra de metal
sólido adecuado cercano al amplificador
yconecte el cable de alimentación negativo
a este utilizando tornillería apropiada.
Use un cable de alimentación del mismo
calibre que el cable conectado a la conexión
“+12VDC” (mínimo, calibre 4 AWG), de
90 cm (36 pulgadas) de largo como máximo
desde el amplificador hasta el punto
detoma a tierra. En algunos vehículos,
puede ser necesario aumentar el calibre
del cable a tierra de la batería. (Consulte
elaviso importante de la página 5).
Monte el amplificador de manera segura

7)
usando la tornillería adecuada.

8) Conecte los cables de alimentación positivo
y negativo al amplificador.

9) Conecte el cable de encendido remoto
alamplificador.

10) Conecte los cables de entrada
alamplificador.

11) Conecte los cables de los altavoces
alamplificador.

12) Revise con atención los ajustes de control
del amplificador para asegurarse de que
se hayan configurado de acuerdo con las
necesidades del sistema.

13) Instale el fusible del cable de alimentación
(50A para un único JX360/2) y vuelva
aconectar el terminal del polo negativo
dela batería.

14) Encienda la unidad fuente a un nivel
bajo para comprobar nuevamente que
el amplificador se haya configurado
correctamente. Resista la tentación de
subir el volumen al máximo hasta que haya
verificado los ajustes de control.

15) Haga los ajustes necesarios en los controles
de amplificación de entrada para obtener
la salida general adecuada y el balance
deseado en el sistema. Consulte el
Apéndice A (página12) para el método
de configuración recomendado para
laamplificación de entrada.

16) Disfrute del trabajo realizado escuchando

CONEXIONES DE ALIMENTACIÓN

Antes de instalar el amplificador, desconecte
elcable negativo (tierra) de la batería del
vehículo. Esto servirá para evitar daños
accidentales al sistema, al vehículo y a usted
mismo durante la instalación.

+12 VDC Ground Remote

Las conexiones “+12 VDC” y“Ground”
(Atierra) del JX360/2 están diseñadas para
aceptar cables de alimentación calibre 4 AWG.

Elcalibre mínimo del cable de alimentación
para este amplificador es calibre 4 AWG.

Si instala el JX360/2 con otros amplificadores
y desea usar un único cable de alimentación
principal, use un cable de alimentación principal
calibre 2 AWG o más grueso. Esto dependerá
de la demanda de corriente general de todos
los amplificadores del sistema. Este cable de
alimentación calibre 2 AWG o más grueso debe
terminar en un bloque de distribución situado
lo más cerca posible de los amplificadores
ydebe conectarse al JX360/2 con un cable
dealimentación calibre 4 AWG.

Nota: Cuanto menor es el número del AWG,
mayor es el calibre del cable y viceversa.
(Elcablecalibre 1/0AWG es el más grande,
elcalibre 2 AWG es más pequeño, después
elcalibre 4AWG, calibre 8 AWG, etc.)

Para conectar los cables de alimentación

yde toma a tierra al amplificador, pele 12mm
(0,5 pulgada) de aislamiento de cada cable
e inserte el cable pelado en las posiciones
apropiadas del bloque de terminales del
JX360/2. Use la llave hexagonal de 2,5mm
provista para sujetar el cable con un tornillo
en la parte superior de cada terminal.

La conexión “GROUND” (A tierra) debe
realizarse usando cable calibre 4 AWG y debe ser
lo más corta posible, con acceso a una chapa
metálica en el vehículo. La superficie de la chapa
metálica debería pulirse en el punto de contacto
para crear una buena conexión entre metales
entre el chasis y la terminación del cable de
toma a tierra. Es aconsejable usar un tornillo
para chapa n.º 10 y una arandela en estrella

para asegurar la conexión. Puede utilizar, de

manera alternativa, un conector de toma a tierra
especializado como el XB-MGLU de JL Audio.

Se deben proteger todos los cables que
atraviesen barreras metálicas, como los
cortafuegos, con una goma de aislamiento de
alta calidad a fin de evitar daños al aislamiento
del cable. En caso contrario, podría producirse
uncortocircuito peligroso.

IMPORTANTE

!

En muchos vehículos, se utilizan cables
pequeños (calibre 10AWG - calibre 6 AWG)
para conectar la batería a tierra en el chasis del
vehículo y para conectar el conector positivo
del alternador a la batería. Con el fin de evitar
caídas de voltaje, el calibre de estos cables
sedebe aumentar a calibre 4 AWG cuando
seinstalan sistemas de amplificadores con
fusible principal de más de 60 A.

REQUISITOS DEL FUSIBLE

Es esencial usar un fusible apropiado
enlos cables de alimentación principales a los
amplificadores para la seguridad del vehículo.
Este fusible debe instalarse a 45 cm (18 pulgadas)
como máximo de la conexión del polo positivo
de la batería. Si el JX360/2 es el único dispositivo
conectado a este cable principal, use un fusible
AGU o MAXI® de 50A (no se requiere otro
fusible en este caso).

Cuando se conectan varios dispositivos
auncable de alimentación principal, el valor del
fusible principal y la potencia nominal del cable
de alimentación principal deben tener capacidad
suficiente para todos los equipos instalados.
Use un bloque de distribución con fusibles para
dividir la potencia del cable de alimentación

su música favorita.
