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.
Mounting the amplifier upside down is
strongly discouraged.
If mounting the amplifier under a seat, make sure
there is at least 1 inch (2.5 cm) of space above the
amplifier’s outer shell to permit proper cooling.
Safety Considerations:
Your amplifier needs to be installed in a dry,
well-ventilated environment and in a manner
which does not interfere with your vessel’s factory
installed electronic devices.You should also take the
time to securely mount the amplifier using the
supplied screws so that it does not come loose in
the event of a collision or a sudden jolt to the
vessel (12 lbs. of aluminum traveling at 30 MPH will
hurt you).
Stupid Mistakes to Avoid:
• Check before drilling any holes in your vessel to
make sure that you will not be drilling through the
hull, a fuel tank, fuel line, wiring harness or other
vital vessel system.
• Do not run system wiring outside or underneath
the vessel.This is an extremely dangerous practice
which can result in severe damage to your vessel
and person.
• Protect all system wires from sharp edges
(metal, fiberglass, etc.) by carefully routing them,
tying them down and using grommets and loom
where appropriate.
• Do not mount the amplifier in the engine
compartment or in any other area that will
expose the amplifier circuitry to the elements.
While this amplifier is specially designed for marine
applications, it is not waterproof and it should not
be mounted where it is likely to get wet.

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. 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 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
with 12V, negative-ground electrical systems. Use of
this product in vessels with positive ground and/or
voltages other than 12V 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.
