WHY YOU SHOULD PAY ATTENTION TO THIS OWNER'S MANUAL
The performance of your vehicle's audio system depends as much on quality installation and setup as it does on
quality gear. Of course, these new
JBL ® GTO amplifiers are bulletproof perfo rm ers that are built using the highest
quality components, and will outperform any competing prod
uct on the test bench. To make sure you extract all
the performance possible from your new amp, whether you install it yourself or have a professional install it for you,
we've incorporated some new features that make se
tup simple and precise and ensure you get al l the power and
performance you've paid for.
WHAT MAKES THESE AMPLIFIERS DIFFERENT
All amplifiers include some signal processing functions, level setting controls and other switches and co nnectors that
make it possible to hook the amp up
to just about any existing system. However, with many amplifiers, considerable
technical expertise
is required to make the best use of those connectors, switches and controls to get powerful noise-
free sound.
JBL GTO amplifiers include Simple Setup designed to make it easy for you to get all the noise-free power
yo
ur amp is capable of delivering.
WHAT MAKES INPUT SETUP EASY
GTO Amplifiers include adapters for connecting almost any analog signal and feature built-in Gain Indicator LEOs and
a setup CD that makes precision adjustment simple, no matter your level
of experience. The setup of GTO amplifiers is
a little different than amplifiers you may have installed
in the past, so please read this owner's manual before you
begin. If you're an experienced installer, skipping ahead is OK,
but please don't skip Setup Procedure, on
page 8.
So we can better serve you should you require warranty se rvice, please retain your orig in al sal es receipt and register
your
GT0-804EZ or GT0-504EZ online at www.jbl.com.

LOCATION AND MOUNTING
INSTALLATION WARNINGS AND TIPS
IMPORTANT: Disconnect the vehicle 's negative(-) battery terminal before beginning the installation.
• Always wear protective eyewear when using tools.
• Check clearances on both sides of a planned mounting surface. Be sure that
sc rews or wires wi ll not puncture
br ake lines, fuel lin es or wiring harnesses, a nd tha t wire routing will not interfere with the safe operation of the
vehicle.
•
Wh en making elect ri cal co nnection s, make sure they are secure and pro per ly insulated.
• If you must replace any
of the GT 0-804E Z/GT0 -504EZ's fuses, be sure to use the same type of fuse and curre nt
rating as that of the origina l.
INSTALLATION LOCATION
Amplifiers need air circ ul ation to stay coo l. Select a location th at pr ovides enough air for the a mp to coo l itself.
• Suitable locations are under a seat (provided the amplifier doesn't interfere with the seat adjustment mechanis
m) ,
in the trunk, or in any ot her l oca tion that provides enough c oo ling air.
• Do not mount the amplifier with the heatsink f
ac ing downward, as this in terferes with the ampl if ier's convection
coo ling.
• Mount
th e amplifier so that it will not be damaged by the feet of backseat passengers or shifting car go in the trunk.
• Mount the amplifier so that it rema
in s dry -never mount an amplifier outside the car or in th e engine co mpartment.

MOUNTING THE AMPLIFIER
NOTE:
You
may find it more convenient
to
make
all
of the connections to the amplifier
bef
o
re
you permanently mount
it to the vehicle.
Before mounting the amplifier you must remove the two end caps
to
expose the mounting holes and the connections.
Using a Phillips screwdriver, remove the attachment screws and then the end caps, as shown
in
the illustration.
Pu
t
the screws
in
a safe place, so you can use them
to
reattach the end caps after you have made all the
co
nnections
to
the amplifier.
NOTE:
Before you permanently mount the
amp
lifier, read
Auto
Turn-On Switch, below,
to
determine the setting of the
switch, which
is
located on the amplifier's bottom panel.
1.
Sele
ct
a suitable mounting location as described above.
2. Using the amplifier as a template, mark the l
oc
ations of the mounting holes on the mounting surface.
3.
Drill pilot holes
in
the mounting surface.
4.
Attach the amplifier
to
the mounting surface with four appropriate mounting screws
of
your own choice. We
suggest using #8 Phillips-head sheet metal
sc
rews. Make sure the amplifier
is
mounted securely.

CONNECTING THE POWER AND GROUND
The GTO se ri es amplifiers are capable of delivering extremely high po wer levels, a nd require a h ea vy-du ty and
reliable connection
to the vehicle 's el ectrical system to achieve optimal performance. Please adhere to the following
instructions carefully.
Using the Connectors
GTO series amplifiers use the same type of screw terminals for power and speaker co nnections. This type of terminal
is easy
to use, provides superior current transfer and all ow s the easy connection of large-gauge wire.
To use the co nnectors, use a Phillips screwdriver to loosen the connector' s set scr ew, insert th e bare wire and tighten
the set scr
ew to secure the wire in the connector.

SETUP PROCEDURE
GTO series amplifiers include a setup CD with test signals that makes it easy to precisely set the amplifier's input gain to
maximize the amplifier's signal-to-noi
se and dynamic range performance with your vehicle's audio system. The amplifiers
feature three Gain Indicator LEOs th
at provide all the feedback you need to qu ickly set the gain to th e proper level.
CONTROLS
Before setting the amplifier controls: Confirm that all connections have been correctly made, reconnect the
vehicle's negative (-) battery terminal and turn the audio system on.

Front Channel Controls Rear Channel Controls
SET THE CROSSOVER
Before yo u set the amplifier's gain, we recommend th at you set the Crossover co ntrols for the speakers that you have
co
nn ected to each of the amplifier's cha nn el s.
Crossover Filter Selector
The Crossover Filter Selector lets you configure the front a nd rear channels f or either high-pass, l ow-p ass or full-range
operation. NOTE: The rear-channel Bass Boost control makes the rear channels preferable
for s ubwoo fer operation.
See Bass B
oos t, on page 10.
•
If you have connected a subwoofer or woofer to the rear amplifier channels: Set th e Crossover Filter
selec
tor in the "LP" (l ow-pass) p os itio n. T hi s will limit the amount of high-frequency energy sent to the w oo fers or
s
ubwo of er .
•
If you have connected any other type of speaker to the amplifier channels: Set the Crossover Filter selec to r
in the "HP" (high-pass) positio n. This will limit the amount of low-frequen cy energy sent to t he spea ker, significantly
reducing distortion and preventing the speaker from damage. Exception: If you have connected large full-range
speakers (6" x 9" or larger) that can handle significant bass to the amplifier channels and you are
not us in g a
subwoofer
in the system, set the Crossover Filter selector for fu ll -range operation (the s wit ch 's center position ).
Crossover Control
The Crossover control determines the fre qu en cy wh ere the low frequencies or high frequencies sent to the speakers
beg
in to be reduced in volume.
•
High-pass operation: For hi gh-pass filters, you sh ou ld se t the Crossover co ntrol acco rding to the si ze of the
speakers connected to the amp
lifi er cha nn els - the sma ll er the speakers the hi gher you need to set the control to
prote
ct the speaker from damage. The illus tr a ti on below shows the acceptable crossover filter fr equency ra ng es

dis
tr ess.

• Low-pass operation: The low-pass Crossov er control setting you use for subwoofers wi ll depend partly on the
settings you use for
the system's high-pass channels (see abo ve) and partly on the type and location of your
system's subwoofer. Start
by setting the Crossover control to a frequency somewhat lower than the lowest
setting you used
on any of the high-pass channels. After listening to music on the system for a time, fine-tune the
low-pass Crossover control setting
to achieve a smooth transition from the subwoofer to the rest of the system's
speakers while avoiding a "hole," where the sounds that
occur bet ween the subwoofer and other speakers seem
to drop out. The illustration below shows the acceptable low-pa ss Crossover co ntrol frequency range.

SET THE GAIN
Before beginning, make sure the Gain LEOs sw itch is set to the "O n" position.
1. Initially set the amplifier Input Level switch to the "Hi1" position.
NOTE: If you have connected the GT0-804EZ or GT0-504EZ amp li fier to your factory audio system's speaker
out put s, the audio system may show a "speaker disconnected" message, or may fa il to play with an amp lifier
co nnected to its output. If this happen s, set the GTO amplifier's I np ut Level sw i tc h to the " Hi 2" po sition. The " Hi 2"
position
in c lu des a circuit de signed to fool this type of factory system into "seeing" a speaker connected to its output.
2. Turn a
ll amplifier Gain controls to the "Min" setting.
3. Play the supplied setup CD through the vehicle's audio system.
4. Set the audio system head unit's volume
to ma ximum (all the way up).
5. SLOWLY advance
th e Gain control setting. The Gain In dicat or LEO s will li ght up:
• Ye
ll ow LED = Gain is too l ow
• Green LED = Gain is OK
• Red LED = Gain is t oo hi gh
6. SLOW
LY advance th e Gain control so that the green Gain Indi ca tor LED li ghts up. If you overshoot and the red
LED
li ghts up, turn th e Ga in co ntrol down so that the ye ll ow LED lights up and advance the Gain co ntr ol SL OW LY
until the green LED
li ght s up.
Gain
too low
(increase gain) Gain
too high
(decrease gain) Gain
OK
NOTE: If you advan ce the Ga in control all the way and the ye ll ow LED is still lit up, turn the Gain con tr ol to "Min,"
switch the
In put Level switch to the "Lo w" pos iti on and repeat Step 6.
7. Repeat Steps 5 and 6 for a
ll of th e amp lifier channels. When a ll Ga in In dicator LE Os are li t green, the GTO
amplifier
ga in setup is co mplete.
NOTE: Set the amp lifier's Ga in LEO s sw itch to the "Off" pos ition to prevent the red LEOs fr om li ghting up
cont inua ll y during normal operatio n.

BASS BOOST
When you're using the amplifier's
rea
r channels
to
power a subwoofer,
th
e Bass Boost control can provide up to
12dB
of
bass boost at 45Hz. Set this control according to your personal taste, but be careful not to set the control at a high
enough
le
vel
to
cause audible d
is
tortion
or
bottoming of your subwoofer. CAUTION: Only use the Bass Boost control
if you've
co
nfigured the rear channels
to
power a subwoofer. Using the Bass Boost control with full-range speakers
can damage the speakers.

CAUSES AND SOLUTIONS
• Check that the amplifier's +12Vand GND connections have been properly
made.
• Check if the fuse on the +12V wire located near the battery is blown; if so,
replace it with an identical fuse.
• Check all amplifier fuses; if any are blown, replace them with identical fuses.
• If you are using the amplifier's
RE M connection for turn-on, check that the
wire is properly connected
to the audio system's re mote turn-on wire or to the
vehicle's ACC
power terminal.
• If you are using the amplifier's Auto Turn-On circuit for turn-on,
check that the
amplifier's Auto Turn-On switch (on the amplifier's bo
ttom panel) is set in the
"On" position.
o Check that all amplifier input and speaker connections have been properly
made.
o Check that the amplifier's Gain controls ar e not turn ed all the way down .
o Check that the vehicle audio system's source unit's volume control is not
turned all the way down.
• Confirm that the vehicle's electrical system
is supp lying between 9V and 16V
DC
to th e amplifie r. If the s up ply voltage is outside of this range, correct the
condition before a
tt empting to use the amplifie r.
o If th e amplifier has overheated, wait until it has cooled down before att empting
to use it again.
• Disconnect
all speakers from the amplifier and attem pt to turn it on again:
-If the amplifier turns on (the Power/Protect LED is orange), there is a short
circuit in one
or more of the speaker wires. Correct a ll short circuits bef or e
re
conn ecting the speakers to the amplifie r.
-If th e amplifier does not turn on (the Power/Prote ct LED is still red), contact
your authorized
JBL dealer for assistance.
• Check that the settings
of the amplifier's Input Routing switches match the
input and speaker connections made
to the amplifier.
o Check that the vehicle audio system 's source unit's balance and fader controls
a
re set to their center (midpoint) position s.
o Check the amplifier 's Input Level switc h. If it is s et to "H i1 ,"turn the amplifier's
Gain co
nt rols a ll the way dow n and reset the Input Level switch to "Low." Then
perform the Set the Ga
in proc edure, on page 9, again.
• If the amplifier channel
s' Input Le vel switch is set in the "Lo w" position, change
the setting to "Hi1" and perform the Set the Gain procedure, on page 9, again
for
tho se channels.
o Make sure amplifier's Cr ossover Filter s el ector for the distorted channels is set

We need to
hear from you!
• Warranty Service
•
Confirmation of Ownership
In the world of high fidelity,
technology is all too often viewed as the
end product. At JBL~ we have a different
viewpoint: technology is only the means to
an end. The end result must be enjoyment
of the programs and music you hear.

one
(1)
year

labor)
for
all
loudspeaker

electronic
components
from
any
failure
as
a
result

HOW
CAN WARRANTY
SERVICE
BE
OBTAINED?
In
the
event

require
service,
you
should
first
contact
either
the
JBL
dealer
from
whom
the
product
was
purchased
or
an
authorized
service
center.
For
the
name
of
a

at
JBL
(ATTN:

or
call
516.255.4JBL
(4525).
We
may
direct
you
to
an
authorized
service
center
for
JBL
products
or
ask
you
to
send
the
product
to
us
for
repair.
In
either
case,
you
will
have
to
present
your
original
Bill
of
Sale
to
establish
warranty
coverage.
Do
not
send
your
product
to
us
without
prior
authorization
from
our
Customer
Service
Department.
You
are
responsible
for
transporting
your
product
to
either
JBL
or
an
authorized
service
center
and
for
payment
of
all
shipping
charges;
however,
JBL
will
pay
the
return
shipping
charges
(in
the
event
you
return
the
product
to
us)
if
the
repairs
are
covered
by
warranty.
If
you
experience
difficulty
in
transporting
your
product
or
are
in
need
of
packing
materials,
please
advise

and
we
may
be

LIMITATION
OF
IMPLIED WARRANTIES:
All
implied
warranties,
including
fitness
for
a
particular
purpose
and
merchantability,
are
limited
in
duration
and
length
to
the
warranty
period
for
your
product.
LIMITATION OF INCIDENTAL
OR
CONSEQUENTIAL DAMAGES:
JBL
is
not
responsible
for
incidental
or
consequential
damage
of
any
kind.
Our
liability
is
limited
to
the
repair
or
replacement,
at
our
option,
of
a
defective
product.
Some
states
do
not
allow
limitations
on
how
long
an
implied
warranty
lasts
and/or
do
not
allow
the
exclusion
of
incidental
or
consequential
damages,
so
the
above
limitations
or
exclusions
may
not
apply
to
you.
This
warranty
gives
you
specific
legal
rights
and
you
may
also
have
other
rights,
which
vary,
from
state
to
state.
NOTE:
In
the
event
that
there
is
a
difference
between
this
warranty
and
the
provisions
in
any
advertisements,
product
brochure
or
packaging
cartons,
the
terms
of
this
warranty
will
prevail.
JBL
continually
strives
to
update
and
improve
existing
products,
as
well
as
create
new
ones.
The
specifications
and
construction
details
in
this
and
related
JBL
publications
are,
therefore,
subject
to
change
without
notice.
