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 person during installation.

Monoblock Subwoofer Amplifier
+12V battery Connection
You will need to connect a power wire to
the vehicle’s positive battery terminal, using an
appropriate power ring or specialized battery
terminal connector, such as the JL Audio
XB-BTU or XD-BTS. This connection must
be tight and corrosion-free to ensure proper
connectivity. This wire MUST be fused
appropriately for safety. Any power 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.
Power wire requirements
The 600/1v3’s “+12 VDC” and “Ground”
connections are designed to accept 4
AWG power wire. 4 AWG pure copper
wire is recommended for any power wire
run longer than 72 inches (180 cm).
If you are installing the 600/1v3 with
other amplifiers and wish to use a single
main power wire, use 2 AWG or 1/0 AWG
pure copper wire as a main power wire.
This 2 AWG or 1/0 AWG power wire should
terminate into a fused distribution block
mounted as close to the amplifiers as possible
and should connect to the 600/1v3 with 4
AWG or 8 AWG pure copper power wire.
Please note that lower 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.).
I M P O R TA N T
!
We do not recommend the use of “copper-
clad aluminum wire” or “CCA” wire because
this wire is significantly less conductive than
pure copper wire. Only use pure copper power
wire, such as JL Audio’s Premium Power Wire.
Tinned copper wire (silver color) is acceptable
as the tin-plating is only a very minor
component of the wire.
Fuse requirements
The installation of a fuse on the main
power wire, within 18 wire inches (45 cm)
of the positive battery terminal is vital to
protect the wire and the vehicle from fire in
the event of a collision or short-circuit. The
fuse value at each power wire should be just
high enough for all of the equipment being run
from that power wire. Do not use a fuse with
a value that far exceeds the total fuse rating
of the electronics connected to the wire.
If only the 600/1v3 is being run from that
power wire, we recommend a 60A fuse be
used. AGU (big glass fuse) or MaxiFuse™ (big
plastic-body fuse) types are recommended.
If other amplifiers are also being powered from
a main power wire and exceed 80 amps in total
fuse rating, we recommend the use of an ANL
(large-blade) fuse and holder at the battery plus
a fused distribution block near the amplifiers.
Each amplifier must be fused independently at
the outputs of the fused power distribution block.
We recommend appropriately rated MaxiFuse™
fuses and a JL Audio fused distribution block.
Please consult with your JL Audio
dealer to make sure that the wire, fuse
holder and fuse ratings are appropriate
for your system’s needs. The safety of
your installation depends on appropriate
power connections and fuse protection.
ProduCt desCriPtion
The JL Audio 600/1v3 is a monoblock
subwoofer amplifier utilizing proprietary and
patented Class D technology. Its frequency
response is limited to the range below 250 Hz. It
is not designed for driving midrange speakers or
tweeters. Every aspect of its operation has been
optimized for low-frequency amplification.
For detailed specifications, please refer to
Appendix B (page 15).
tYPiCal installation sequenCe
The following represents the sequence for
a typical amplifier installation, using an
aftermarket source unit or OEM Interface
processor (like the CleanSweep® CL441dsp).
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 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. 4 AWG is recommended
for wire runs greater than 72 inches (180
cm) in length. Use of 8 AWG power wire is
acceptable for shorter runs, such as from a
power distribution block to the amplifier or
from a trunk-mounted battery. Use a 2 AWG
or 1/0 AWG main power wire with a fused
power distribution block when additional
amplifiers are being installed with the 600/1v3
and powered from the same main power wire.
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 connected to the amplifier.
4) Run signal cables (RCA cables) and remote
turn-on wire from the source unit or interface
processor to the amplifier mounting location.
5) Run speaker wire from the speaker systems to
the amplifier mounting location.
6) Find a good, solid, bare metal grounding
point close to the amplifier and connect the
negative power wire to it using appropriate
hardware. Use minimum 4 AWG wire up to
60 inches (150 cm) long from the amplifier
to the ground connection point. In some
vehicles, it may be necessary to upgrade the
battery’s ground wire as well. (See page 6 for
important notice).
7) Securely mount the amplifier using
appropriate hardware.
8) Connect the remote turn-on wire and the
positive and negative power wires to the
amplifier’s power connector plug. Then insert
the power connector plug into the amplifier’s
power connector receptacle, pushing firmly.
9) Connect the RCA input cables
to the amplifier.
10) Connect the speaker wires to the speaker
connector plug and insert the plug firmly into
the speaker connector receptacle.
11) Carefully review the amplifier’s control
settings to make sure that they are set
according to the needs of the system.
12) Install power wire fuse (60A for a
single 600/1v3) and reconnect the negative
battery post terminal.
13) 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.
14) Make necessary adjustments to the input
sensitivity controls to obtain the right
overall output and the desired balance
in the system. See Appendix A (pages 14)
for the recommended input sensitivity
setting method.
15) Enjoy the fruits of your labor with your
favorite music.
