THANK YOU
for purchasing a JBL marine amplifier. In
order that we may better serve you should
you require warranty service for your
new amplifier, please retain your original
purchase receipt and register your new
JBL amplifier online at www.jbl.com.
WARNING
Playing loud music in a boat can hinder
your ability to hear other boats, passengers
and nearby swimmers and can permanently
damage your hearing. We recommend
listening at low or moderate levels while
operating your boat. JBL accepts no liability
for hearing loss, bodily injury or property
damage resulting from the use or misuse
of this product.
IMPORTANT
To get the best performance from your
JBL marine amplifiers, we strongly
recommend that installation be entrusted
to a qualified professional. Although
these instructions explain how to install
these amplifiers in a general sense, they
do not show specific installation methods
that may be required for your particular
application. If you do not have the
necessary tools or experience, do not
attempt the installation yourself. Instead,
ask your authorized JBL car audio or marine
audio dealer about professional installation.
NOTE: This marine product is not intended
for automotive applications.
INSTALLATION
WARNINGS AND TIPS
• Always wear protective eyewear when
using tools.
• Turn off the audio system and other
electrical devices before you start.
Disconnect the (–) negative lead from
your boat’s battery.
• At the installation sites, locate and
make a note of all fuel lines, hydraulic
brake lines, vacuum lines and electrical
wiring. Use extreme caution when cut-
ting or drilling in and around these areas.
• Check clearances on both sides of
a planned mounting surface before
drilling any holes or installing any
screws. Remember that the screws
can extend behind the surface. Do not
use screws long enough to penetrate
the boat’s hull.
• Before drilling or cutting holes, use a
utility knife to remove unwanted fabric
or vinyl to keep material from snagging
in a drill bit.
• When routing cables, keep input-signal
cables away from power cables and
speaker wires.
• When making connections, make
certain they are secure and properly
insulated.
• If the amplifier’s fuse must be replaced,
use only the same type and rating as
that of the original. Do not substitute
another kind.
CHOOSING A LOCATION
AND MOUNTING THE
AMPLIFIER
Choose a mounting location in the
cargo area where the amplifier will not
be damaged by shifting cargo or water.
Although these JBL marine amps are
designed for use on a boat, they will not
withstand submersion. Amplifier cooling
is essential for proper amplifier operation.
If the amplifier is to be installed in an
enclosed space, make sure there is
sufficient air circulation for the amplifier
to cool itself.
Make sure that the amplifier is mounted
securely using nuts and bolts or the
supplied mounting screws.
