ABOUT THESE 
INSTRUCTIONS
Installation of automotive stereo
components can require extensive
experience with a variety of
mechanical and electrical proce-
dures. Although these instructions
explain how to install Power Series
Component Systems in a general
sense, they do not show the exact
installation methods for your
particular vehicle. If you do not feel
you have the experience, do not
attempt the installation yourself,
but instead ask your authorized JBL
car audio dealer about professional 
installation options.

LOUD MUSIC AND
HEARING
Playing loud music in an auto-
mobile can hinder your ability to
hear traffic, as well as permanently
damage your hearing. The maxi-
mum volume levels achievable with
JBL speakers, combined with high
power amplification, may exceed
safe levels for extended listening.
We recommend using low volume
levels when driving. 
JBL accepts no liability for hearing
loss, bodily injury or property 

damage as a result of use or 

misuse of this product.

REAR DECK 
PRECAUTION
In some cars, fuel tanks may be
located directly beneath the rear
deck. Before installation, make
sure there is adequate speaker
basket clearance before
considering this location!

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 vehi-
cle’s 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,
hydraulic brake lines, vacuum
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.

• For door installations, check the

clearance with the windows
throughout the range of the
window’s travel, and verify that a
mounted speaker will not inter-
fere with the window crank or
power window mechanism. 

• If mounting speakers elsewhere,

check for clearance around rear
deck torsion bars, glove box or
other structural elements.

• Do not mount speakers where

they will get wet.

• If possible, select a mounting site

for the crossover network that is
near the speakers and provides
easy access for connections.
