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.

The XD1000/1v2’s “+12 VDC” and

“Ground” connections are designed to

accept 4 AWG power wire. 4 AWG is the

required wire size for this amplifier.

If you are installing the XD1000/1v2 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 fused distribution block mounted as close

to the amplifiers as possible (within 12 inches

/ 30cm of wire length). The fused output of

the distribution block will connect to the

XD1000/1v2 with 4 AWG power wire. JL Audio

ECS fused distribution blocks are recommended

(XD-FDBU-2 and XD-FDBU-4)

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 wires to the amplifier,

first back out the set screw on the top of the

terminal block, 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 terminal block, 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.

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 rubber grommet to prevent damage to the

insulation of the wire. Failure to do so may result

in a dangerous short circuit.

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

It is absolutely vital that the main power

wire(s) 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 XD1000/1v2 is being run from that

power wire, use a 80A fuse.

If fusing the amplifier near its power

connections (when more than one amp is being

run from the main power wire), use an 80A fuse

(MAXI™ big plastic-body fuse is recommended).

PRODUCT DESCRIPTION

The XD1000/1v2 is a monoblock

amplifier utilizing JL Audio NexD™ high

speed switching technology to deliver

outstanding fidelity and efficiency.

The XD1000/1v2 can be operated with a wide

variety of source units and system configurations.

Its frequency response is limited to the range

below 500 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 C (page 13).

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 reconnection 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 fused power distribution block if

additional amplifiers are being installed with

the XD1000/1v2.

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 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 of the JL Audio ECS master

ground lug, XB-MGLU is recommended).

Use 4 AWG 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.

8) Connect the positive and negative power

wires to the amplifier. A fuse near the

amplifier is not necessary if the XD1000/1v2

is the only device being run from the fused

main power wire. If the fused main power

wire is shared by the XD1000/1v2 and other

amplifiers or devices, fuse each amplifier/

device within 12 inches (30 cm) of wire

length, via a fused distribution block

or multiple individual fuse blocks/

on-board fuses.

9) Connect the remote turn-on wire

to the amplifier or configure the “Turn-On

Mode” switch for automatic turn-on.

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 (80A for a

single XD1000/1v2) and reconnect the

negative battery post terminal. Install the fuse

(80A) near the amplifier (if applicable).

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.
