PRODUCT DESCRIPTION
The JL Audio JX360/4 is a four-channel,
full-range audio amplifier utilizing Class A/B
technology for all channels.
The JX360/4 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 JX360/4.
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 “
+12VDC
” 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 JX360/4) 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.
