ABOUT THESE
INSTRUCTIONS:
Installation of marine audio 
components can require extensive
experience with a variety of
mechanical and electrical 
procedures. Although these 
instructions explain how to install
JBL marine speakers in a general
sense, they do not show the exact
installation methods for your 
particular application. If you do not
feel you have the experience, do 
not attempt the installation yourself. 
Ask your authorized JBL marine
audio dealer about professional
installation options.

LOUD MUSIC AND
HEARING: 
Playing loud music in a marine
environment can permanently
damage your hearing, as well as
hinder your ability to hear marine
traffic. The maximum volume levels
achievable with JBL speakers,
combined with high-power
amplification, may exceed safe 
levels for extended listening. 
JBL accepts no liability 
for hearing loss, bodily injury or
property damage as a result of 
use or misuse of this product.

GENERAL CARE:
The loudspeaker grilles may be
cleaned with a damp cloth. Do not
use any cleaners or solvents on the
grilles or the speaker cones.

ABOUT POWER
HANDLING:
JBL marine speakers will produce
reasonable volume levels with little
amplifier power. Moreover, adding 
an amplifier to drive your speakers
and a subwoofer will enhance your
system’s dynamic range and help
overcome ambient noise.

Although JBL marine speakers are
designed to handle the power of a
dedicated amplifier driven at or
below its rated power, make sure
the amplifier is not driven far above
its rated power. Doing so will “clip”
the output signal and can damage
any speaker. Distorted or “fuzzy”
sound from your speakers is an 
indication that the amplifier has
exceeded its rated power, and you
should reduce the volume level.

INSTALLATION TIPS:
• Always wear protective eyewear

when using any tools.

• Turn off all audio components and

other electrical devices before you
start. Disconnect the negative (–)
lead from your battery.

• Keep speakers in their package

until final installation. When mov-
ing a speaker, always rest it with
the cone or dome facing up. Never
use force to install any speaker.

• 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.

• At the installation sites, locate 

and make a note of all fuel lines
and electrical wiring. Use extreme 
caution when cutting or drilling 
in and around these areas.

• Before drilling or cutting holes, use

a utility knife to remove unwanted
fabric or vinyl to keep material from
snagging in a drill bit or saw.

• The stainless-steel hardware 

provided with your JBL marine
speakers has been chosen to resist
rust and corrosion.
