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 e1200's “+12 VDC” and “Ground”

connections are designed to accept 8 AWG -

4 AWG power wire. 8 AWG is a minimum

power wire size for this amplifier.

If you are installing the e1200 with other

amplifiers and wish to use a single main power

wire, use 4 AWG or larger main power wire

(depending on the overall current demands of all

the amplifiers in the system).This 4 AWG or

larger power wire should terminate into a

distribution block mounted as close to the

amplifiers as possible and should connect to the

e1200 with 8 AWG - 4 AWG power wire.

Please note that 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

the same gauge wire as the power connection

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 star washer to lock

down the connection is advisable.

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

e1200 is being run from that power wire, we

recommend a 25A fuse be used. AGU (big glass

fuse) or MaxiFuse™ (big plastic-body fuse) types

are recommended.

No fuse is required or recommended directly

before the amplifier power connection. If one is

desired, we recommend the use of a 25A AGU fuse

or MaxiFuse™ type.

PRODUCT DESCRIPTION

The JL Audio e1200 is a monoblock,

full-range amplifier utilizing patented Absolute

Symmetry™ Class AB technology.

The e1200 can be operated with a wide variety

of source units and system configurations.

TYPICAL INSTALLATION SEQUENCE

The following represents the sequence for a

typical amplifier installation, using an aftermarket

source unit. 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 (minimum 8 AWG) from

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 4 AWG or

larger power wire and a power distribution block

if additional amplifiers are being installed with the

e1200.

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 and remote turn-on wire

from the source unit to the amplifier

mounting location.

5) Run speaker wire from the speaker system 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” connection (min. 8 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 the

supplied screws.

8) Connect the positive and negative power

wires to the amplifier. A fuse near the amplifier is

not necessary.

9) Connect the remote turn-on wire

to the amplifier.

10) Connect the input cables to the amplifier.

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 (25A for a

single e1200) 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 10) for the recommended input

sensitivity setting method.

16) Enjoy the fruits of your labor with your

favorite music.
