PROTECT YOUR HEARING!
INSTALLATION APPLICATIONS
We value you as a long-term customer. For
that reason, we urge you to practice restraint in
the operation of this product so as not to damage
your hearing and that of others in your vehicle.
Studies have shown that continuous exposure to
high sound pressure levels can lead to permanent
(irreparable) hearing loss. This and all other
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.
This amplifier is designed for operation in
vehicles with 12V, 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 warranty.
This product is not certified or approved for
use in aircraft.

advanced type of heat management, called
RealSink™. This feature takes advantage of
convection and radiation effects to remove
heat from the amplifier circuitry. For optimum
cooling performance, the vertical heat sinks
located at the back of the amplifier 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, but
you still need to follow some basic guidelines:

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 using appropriate
hardware so that it does not come loose in the
event of a collision or a sudden jolt to the vehicle.
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.).
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.

For detailed specifications, please refer to
Appendix B (page 15).
6) Find a good, solid metal grounding point
close to the amplifier and connect the
negative power wire to it using appropriate
hardware. Use minimum 4 AWG power wire,
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. A fuse near the
amplifier is not necessary.
Before installing the amplifier,
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. For optimal grounding, we recommend
the use of a JL Audio ECS master ground
lug (XB-MGLU). Alternatively, a sheet metal
screw or bolt can be used with a star washer.
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.
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.

9) Connect the remote turn-on wire
to the amplifier.
10) Connect the RCA input cables
to the amplifier.
The 1000/1's “+12 VDC” and “Ground”
connections are designed to accept 4 AWG power
wire. 4 AWG is the only recommended power
wire size for this amplifier.
If you are installing the 1000/1 with other
amplifiers and wish to use a single main power
wire, use 2 AWG or 1/0 AWG main power wire
(depending on the overall current demands of all
the amplifiers in the system). This 2 AWG or
1/0 AWG power wire should terminate into
a distribution block mounted as close to the
amplifiers as possible and should connect to the
1000/1 with 4 AWG power wire.
IMPORTANT
!
11) Connect the speaker wires 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 power wire fuse (100A for a
single 1000/1v2) 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 14)
for the recommended input sensitivity
setting method.
Many vehicles employ small (10 AWG -

connection and secure the disconnected cable
to prevent accidental re-connection during
installation. This step is not optional!
2) Run power wire (minimum 4 AWG)
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 1/0
AWG power wire if additional amplifiers
are being installed with the 1000/1v2.
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

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 (or larger) when installing a 1000/1v2.
FUSE REQUIREMENTS
It is absolutely vital that the main power
lead to the amplifier(s) in the system be fused
within 18 inches (45 cm) of the positive battery
post connection. The fuse value at each power
wire should be high enough for all of the
equipment being run from that power wire.
If only the 1000/1v2 is being run from that power
wire, we recommend a 100A ANL fuse be used.
No fuse is required directly before the
amplifier power connection. If one is desired,
we recommend the use of a 100A ANL fuse for
each 1000/1v2.
Note: that smaller AWG numbers mean bigger
wire and vice-versa (1/0 AWG is biggest, 2 AWG
is smaller, then 4 AWG, then 8 AWG, etc.).
To connect the power wires to the amplifier,
first back out the set screw on the top of the
amplifier, using the supplied 2.5 mm hex wrench.
Strip 1/2 inch (12 mm) of insulation from the
end of each wire and insert the bare wire into the
receptacle on the front panel of the amplifier,
seating it firmly so that no bare wire is exposed.
While holding the wire in place, tighten the set
screw firmly, taking care not to strip the head
of the screw.
16) Enjoy the fruits of your labor with your
favorite music.
5) Run speaker wire from the speaker systems to
the amplifier mounting location.

REMOTE TURN-ON
AMPLIFIER INPUT SECTION
The 1000/1v2 uses a conventional +12V remote
turn-on lead, typically controlled by the source
unit's remote turn-on output. 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 ignition-switched circuit.
The 1000/1's “Remote” turn-on connector is
designed to accept 12 AWG – 8 AWG wire.
12 AWG is more than adequate for this purpose.
To connect the remote turn-on wire to the
amplifier, first back out the set screw on the
top of the amplifier, using the supplied hex
wrench. Strip 1/2 inch (12mm) of wire and
insert the bare wire into the receptacle on the
front panel of the amplifier, seating it firmly so
that no bare wire is exposed. Smaller wire than
12 AWG can be used, but it may be necessary
to strip 1 inch of insulation from the wire and
fold the bare wire in half prior to insertion.
While holding the wire in the terminal, tighten
the set screw firmly, taking care not to strip
the head of the screw and making sure that
the wire is firmly gripped by the set screw.
The 1000/1v2 employs a differential-balanced
input topology that provides the user with a high
degree of input flexibility while retaining superior
noise rejection. This type of circuit also allows
the 1000/1v2 to accept high-voltage inputs from
factory source unit outputs without excessive
distortion or noise problems.
The amplifier will operate with only one input
connection (left or right), but will require an
increase in input sensitivity to overcome the loss
of signal. If a mono input signal is to be run, we

rotary control can be used to match the source
unit’s output voltage to the input stage of 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). To properly set the amplifier
for maximum clean output, please refer to
Appendix A (page 14) in this manual. After
using this procedure, you can then adjust
the level of the amplifier by adjusting the
input sensitivity downward, if the amplifier
requires attenuation to achieve the desired

and possible speaker damage.
2) Input Voltage Range: A wide range of signal
input voltages can be accommodated by
the 1000/1v2’s input section (200mV – 8V).
This wide range is split up into two sub-
ranges, accessible via switches located in the

is useful for certain high-output preamp level
signals as well as speaker-level output from
source units and small amplifiers. To use
speaker-level sources, splice the speaker output
wires of the source unit or small amplifier
onto a pair of RCA cables or plugs or use the

IMPORTANT
!
If you plan to use the “Preamp Output” in
“Full-Range” or “HP” mode to feed a stereo
amplifier, you must connect a stereo signal to
the input of the amplifier. A mono signal into
the amplifier will result in a mono signal out of
the preamp output. (It’s a great amplifier, but it
doesn’t do magic).

The output of the amplifier will decrease
for a given input voltage when the “Input

Conversely, the output will be higher with
the switch in the “Low” position. While this
may sound counter-intuitive, it is correct
as described.

CROSSOVER CONTROLS
PREAMP OUTPUT SECTION
Crossovers are groups of individual electronic
filters which allow only certain frequency
ranges to pass through them by attenuating
frequencies outside the selected range. These
filters allow the user to specify what frequency
range will be sent out of each channel section
of the amplifier. This, in turn, allows each
speaker system to only reproduce a range of
frequencies it is well-suited for, resulting in
reduced distortion and improved fidelity.
Tuning Hint: A trunk mounted sub whose
output has to "fight" through a rear deck or a
back seat often benefits from the 12 dB/octave
slope which lets more upper bass content
pass through. A sub that fires directly into
the listening environment is more likely
to benefit from a 24 dB/octave slope.
The 1000/1v2 incorporates a flexible preamp
output section, designed to make multiple
amplifier systems easy to set up.
The Preamp output can be configured in three

channel. This feature is designed to attenuate
frequencies above its filter frequency, so that the
system’s subwoofers do not reproduce any audible
midrange content.

2) Precise Frequency Selection: The filter
frequency markings on the front panel of
the amplifier are for reference purposes and
are generally accurate to within 1/3 octave
or better. If you would like to select the filter
frequency with a higher level of precision,
consult Appendix C: Chart A-1 (page 16)
of this manual. This chart gives you a more
accurate frequency for each of the forty
detented positions of the frequency selection
control. This method can be very useful if the
amplifier is mounted in a location where you
can’t see the front panel markings easily.

The 1000/1v2 employs JL Audio’s exclusive
Regulated, Intelligent Power Supply (R.I.P.S.)
design. This sophisticated power supply
allows the amplifier to produce its optimum
power (1000 watts x 1) over a wide range of
speaker impedances.
Speaker loads below 1.5Ω nominal are not
recommended and may cause the amplifier
output to distort excessively.
Speaker connections to the 1000/1v2 are
straightforward and take place at the far right of
the front panel. You will notice that there are two

connections are connected in parallel inside
the amplifier. Connecting two speakers, each to
one set of positive and negative terminals, will
result in a parallel speaker connection. If only
connecting one pair of speaker wires, it is not
necessary to use both sets of connections.

designed to accept 12 AWG – 8 AWG wire.
To connect the speaker wires to the amplifier,
first back out the set screws on the top of the
amplifier, using the supplied 2.5 mm hex
wrench. Strip 1/2 inch (12 mm) of insulation
from each wire and insert the bare wire end
into the receptacles on the front panel of the

wire is exposed. While holding each wire in place,
tighten each set screw firmly, taking care not to
strip the head of the screw and making sure that
the wire is firmly gripped by the set screw.

The operation of the R.I.P.S. circuitry is
entirely automatic and adjusts itself every time
the amplifier is turned on according to the lowest
impedance present at the speaker load. There are
no user controls to configure. The system
operates through multiple stages of impedance

activates a “safe” mode which reduces amplifier
power to protect the circuitry from failure (the
yellow LED on the top of the amplifier will

charging system when operated at its limits.
Vehicles with weak charging systems may need
to be serviced and/or upgraded to provide ample

occurs. The amplifier will turn back on when
voltage climbs back above 10 volts. This may
happen in a rapid cycle when bass-heavy program

in your system, have your charging system
inspected to make sure it is working properly.

1)ꢀꢀiPowerw (Green): lights to indicate that the
amplifier is turned on and operating normally.
2)ꢀi Thermalw (Red): lights to indicate that
the amplifier has exceeded its safe operating
temperature, putting the amplifier into a self-

output of the amplifier. The red light will shut
off and the amplifier will return to normal,
full-power operating mode if the heat sink
temperature drops back to a safe level.
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.
3) iLow Ωw (Amber): lights to indicate that the
impedance of the speaker load connected
to the amplifier is lower than the optimum
impedance load range for the amplifier. When
this light is on, a protection circuit engages
and reduces the power output of the amplifier.

short-circuit is detected in the speaker wiring
(this can be a short between the positive and
negative speaker wires or between either
speaker wire and the vehicle chassis).

Input Sensitivity Level Setting
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 by the 1000/1v2) at 3/4
source unit volume.
7) Connect the AC voltmeter to the speaker output
connectors of the amplifier. If the channel
pair is operating in stereo, it is only necessary
to measure one channel. If bridged, make sure
you test the voltage at the correct connectors
(L+ and R–).
8) Increase the iInput Sens.w control until the
target voltage is observed with the voltmeter.
9) Once you have adjusted the 1000/1v2 to
its maximum low-distortion output level,
reconnect the speaker(s). The iInput Sens.w
control can now be adjusted downward if the
amplifier requires attenuation to achieve the
desired system balance.

Intelligent Power Supply (R.I.P.S.) allow
delivery of their rated power when connected
to any load impedance from 1.5 - 4Ω per
channel and when connected to a charging
system with any voltage from 11 - 14.5V. This
design is beneficial for many reasons. One of
these reasons is ease of setup. Because each
JL Audio amplifier will always deliver the
same amount of power within its operational
range of impedances and supply voltages, the
maximum, unclipped output is very predictable.
This makes setting the gain structure via the
input sensitivity controls very simple. Following

refer to Appendix A (page 14). After using this
procedure, you can then adjust the level of the
amplifiers by adjusting the input sensitivities
downward, if the amplifiers require attenuation
to achieve the desired system balance. If the
input sensitivities are adjusted, the amplifiers
must be recalibrated to ensure identical power
output levels.

APPENDIX E: TROUBLE SHOOTING
“How do I properly set the input sensitivity on my amplifier”
Please refer to Appendix A (page 14) to set the input sensitivity for
“My amplifier shuts off once in a while, usually at higher volumes”
Check your voltage source and grounding point. The power supply

“My amplifier doesn’t turn on”
of the 1000/1v2 will operate with charging system voltages
down to 10V. Shutdown problems at higher volume levels
can occur when the charging system voltage drops below
10V. These dips can be of very short duration making them

To ensure proper voltage, inspect all wiring and termination
points. It may also be necessary to upgrade the ground
wire connecting the battery to the vehicle’s chassis and the
power wire connecting the alternator to the battery. Many
vehicles employ small (10 AWG - 6 AWG) wire to ground the
battery to the vehicle’s chassis and to connect the alternator 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. Grounding problems are the
leading cause of misdiagnosed amplifier “failures.”
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
i+12VDCwꢁꢀꢀiGroundwꢁꢀꢀBOEꢀiRemotewꢀUFSNJOBMT. 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 i+12VDCw wire
to the iRemotew terminal to see if the amplifier turns on.
“I get a distorted / attenuated sound coming out of the speaker(s)”
Check the speaker wires for a possible short, either between the
“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

range / high-pass application). A steady, sufficient voltage
(between 200mV 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.
positive and negative leads or between either speaker lead
and the vehicle’s chassis ground. If a short is present, you
will experience distorted and/or attenuated output. The
iLow Ωw light will illuminate in this situation. It may be
helpful to disconnect the speaker wires from the amplifier
and use a different set of wires connected to a test speaker.
Check the nominal load impedance to verify that the amplifier
is driving a load between 1.5 - 4Ω. JL Audio monoblock
amplifiers have two “+” positive connections and two “–”
negative connections. This is to facilitate multiple speaker
wiring. The two positive and two negative connections are
connected in parallel inside the amplifier. Connecting two
speakers, each to one set of positive and negative terminals,
will result in a parallel speaker connection. In this case,
each of the two loads should have a nominal
impedance between 3 - 8Ω.
Check the input signal and input signal cables to make sure signal
is present at the “Amplifier Inputs” and the cables are not
pinched or loose. It may be helpful to try a different set of
cables and/or a different signal source to be sure.
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.
“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.
