PRODUCT DESCRIPTION
The JL Audio M800/8-24V is an eight-channel,
full-range audio amplifier utilizing JL Audio
NexD™ ultra-high speed switching technology to
deliver outstanding fidelity and efficiency.
The M800/8-24V 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 in a
vessel, 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 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 or vessel operation. Use 2 AWG
or larger power wire and a power distribution
block if additional amplifiers are being
installed with the M800/8-24V.
3) Connect power wire to the positive battery
post. Fuse the wire with an appropriate fuse
block or circuit breaker (and connectors)
within 18 inches (45 cm) wire length of the
positive battery post. This fuse/circuit breaker
is essential to protect the vessel/vehicle. Do
not install the fuse until the power wire has
been securely 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 “+24V”
connection (minimum 4 AWG).
5) Run signal cables and remote turn-on wire
from the source unit to the amplifier
mounting location.
6) Run speaker cable from the speaker systems
to the amplifier mounting location.
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
M800/8-24V is the only device being
run from the fused main power wire. If
the fused main power wire is shared by
the M800/8-24V 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.
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 or circuit breaker
(40A for a single M800/8-24V) and reconnect
the negative battery post terminal. Install
a fuse or circuit breaker (40A) near the
amplifier in multiple amp systems sharing a
main power wire.
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.
