Planning Your Installation; Installation Applications - JL Audio M800/8-24V Owner's Manual

PROTECT YOUR HEARING!
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 vessel
or 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.
While driving, operate your audio system in
a manner that still allows you to hear necessary
noises to operate your vessel or vehicle safely
(horns, sirens, etc.).
SERIAL NUMBER
In the event that your amplifier requires
service or is ever stolen, you will need to have
a record of the product's serial number. Please
take the time to enter that number in the space
provided below. The serial number can be found
on the bottom panel of the amplifier and on the
amplifier packaging.

INSTALLATION APPLICATIONS

This amplifier is designed for operation in
vessels or vehicles with 24 volt, negative-ground
electrical systems. Use of this product in vessels
or vehicles with positive ground and/or voltages
other than 24 V may result in damage to the
product and will void the warranty.
This product is not certified or approved for
use in aircraft.
Do not attempt to "bridge" the outputs of this
amplifier with the outputs of a second amplifier,
including an identical one.

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.
Cooling Efficiency Considerations:
The outer shell of your JL Audio amplifier is
designed to remove heat from the amplifier
circuitry. For optimum cooling performance, this
outer shell 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.
