POWER CONNECTIONS
Before installing the amplifier, disconnect the
negative (ground) wire from the vessel's battery.
This will prevent accidental damage to the system,
the vessel and your body during installation.
The e4300M'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 e4300M 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
e4300M 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.
Any wires run through metal barriers 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 vessels employ small (10 AWG - 6 AWG)
wire to connect the alternator's positive connection
to the battery.To prevent voltage drops, this wire
should be upgraded to 4 AWG when installing
amplifier systems with main fuse ratings above 60A.
It is common for the alternator to be grounded
through its chassis. If the alternator is not grounded
through its chassis and instead employs a small (10
AWG - 6 AWG) wire to connect to ground, this
wire should also 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
e4300M is being run from that power wire, we
recommend a 40A 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 40A AGU fuse
or MaxiFuse™ type.

PRODUCT DESCRIPTION
The JL Audio e4300M is a four-channel full-range
marine amplifier utilizing patented Absolute
Symmetry™ Class AB technology for all channels.
The e4300M 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 positive and negative 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 vessel
operation. Use 4 AWG or larger power wire and
a power distribution block if additional amplifiers
are being installed with the e4300M.
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 vessel. Do not install the
fuse until the power wire has been connected to
the amplifier.
4)
Connect negative power wire to the negative
battery post. Use the same size power wire as the
wire connected to the
“+12V”
connection
(minimum 8 AWG).
5
Run signal cables and remote turn-on wire
from the source unit to the amplifier
mounting location.
6)
Run speaker wire from the speaker systems to
the amplifier mounting location.
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 the power wire fuse (40A for a
single e4300M) 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.
16)
Enjoy the fruits of your labor with your
favorite music.
