THANK YOU 
for purchasing a JBL GTO 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 an automobile 
can hinder your ability to hear traffic and
permanently damage your hearing. We
recommend listening at low or moderate
levels while driving your car. 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 GTO amplifier, we strongly
recommend that installation be entrusted
to a qualified professional. Although these
instructions explain how to install GTO
amplifiers in a general sense, they do not
show specific installation methods that
may be required for your particular
vehicle. If you do not have the necessary
tools or experience, do not attempt the
installation yourself. Instead, please ask
your authorized JBL car audio dealer
about professional installation.
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 vehicle’s battery.
• At the installation sites, locate and
make a note of all fuel lines, hydraulic
brake lines, vacuum lines and electri-
cal wiring. Use extreme caution when
cutting 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.
• 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 trunk 
or cargo area where the amplifier will not
be damaged by shifting cargo. 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.
When mounting the amplifier under a 
seat, ensure that it is clear of all moving
seat parts and does not affect the seat 
adjustments. Mount the amplifier so it 
is not damaged by the feet of backseat 
passengers. Make sure that the amplifier
is mounted securely using nuts and bolts
or the supplied mounting screws.
Mount the amplifier so that it remains 
dry – never mount an amplifier outside 
the vehicle or in the engine compartment.

INSTALLATION 
POWER CONNECTIONS
The GTO amplifiers require a reliable 
connection to the vehicle’s electrical 
system in order to perform optimally. 
See Figures 1 and 2 for terminal 
connection locations. Please adhere 
to the following instructions carefully: 
Ground Connection
Connect the amplifier’s Ground (GND) 
terminal to a solid point on the vehicle’s
metal chassis, as close to the amplifier 
as possible. Refer to the wire gauge chart
to determine minimum wire gauge size.
Sand away any paint from this location;
use a star- type-lock washer to secure
the connection.
Power Connection
Connect a wire (see chart at right for
appropriate gauge) directly to the
vehicle’s positive battery terminal, and
install an appropriate fuse holder within
30cm of the battery terminal. 
Do not
install the fuse at this time. Route the wire
to the amplifier’s location, and connect it
to the amplifier’s Positive (+12V) terminal.
Be sure to use appropriate grommets
whenever routing wires through the
firewall or other sheet metal. 
Failure to
adequately protect the positive wire from
potential damage may result in a vehicle
fire. When you are done routing and con-
necting this wire, you may install the fuse
at the battery.
Remote Connection
Connect the amplifier’s Remote (REM) 
terminal to the source unit’s Remote Turn-
On lead using a minimum of 0.75mm
2
wire.
NOTE: If your source unit does not have a
remote turn-on connection, connect the
amplifier’s (REM) terminal to the vehicle’s
accessory circuit.
Speaker Connections
Refer to the application guides on the
pages that follow. Speaker connections
should be made using a minimum of 
1.5mm
2
wire.

APPLICATIONS 
The GTO4060 can be set up for stereo 
4-channel, 3-channel or bridged 
2-channel operation, as shown in 
Figures 3 through 5
NOTE: For simplicity, Figures 3 through 7
do not show power, remote and input 
connections.
NOTE: Minimum speaker impedance for
stereo operation is 2 ohms.
Minimum speaker impedance for bridged
operation is 4 ohms.
