THANK YOU
for purchasing a JBL CS Series 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 CS Series amplifiers, we strongly
recommend that installation be entrusted
to a qualified professional. Although
these instructions explain how to install
CS 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 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.
• 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 CS amplifiers require a reliable
connection to the vehicle’s electrical
system in order to perform optimally.
See Figures 1, 2 and 3 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 18" 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 connecting 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 18-gauge 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
16-gauge wire.
Wire Gauge Chart
Amplifier Maximum Minimum
Model Current Draw Wire Gauge
CS60.2 22A #8 AWG
CS60.4 40A #8 AWG
CS300.1 42A #8 AWG
These recommendations assume 10' – 12'
wire runs. If your installation differs mark-
edly, you will need to adjust the wire gauge
accordingly.

APPLICATIONS – CS300.1
The CS subwoofer amplifier is a
single-channel amplifier. There are
two sets of terminals to make it easy
to connect multiple woofers. Either
set of (+/–) terminals may be used
when connecting woofers.
To the right are two application
diagrams to help plan your subwoofer
system installation. Figures 4 and 5
show how to configure the CS300.1
subwoofer amplifier.
NOTE: For simplicity, Figures 4 and 5
do not show power, remote and input
connections.
NOTE: Minimum speaker load is
2 ohms total.

APPLICATIONS – CS60.4
The CS60.4 can be set up for stereo
4-channel, 3-channel or bridged
2-channel operation, as shown in
Figures 6 through 8.
NOTE: For simplicity, Figures 6 through
8 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.

CONTROLS AND SETUP
SETTING THE
CROSSOVER(S)
Determine your system plans and set
the crossover mode switch accordingly.
If your system design does not include
a subwoofer with the CS60.4, set the
crossover mode to FLAT and skip to
“Setting Input Sensitivity.”
Initially set the crossover frequency
control midway. While listening to music,
adjust the crossover for the least
perceived distortion from the speakers,
allowing them to reproduce as much
bass as possible.
Systems using a separate subwoofer set
the crossover mode to HP (high pass) for
your full-range speakers. Adjust the
crossover frequency to limit bass and
provide increased system volume with
less distortion.
For subwoofers, choose the highest
frequency that removes vocal information
from the sound of the subwoofer.
If using the CS60.4 or CS60.2 to drive a
subwoofer(s), set the crossover mode to
LP (low pass).
SETTING INPUT
SENSITIVITY
1. Initially turn the INPUT LEVEL control(s)
to minimum (counter clockwise).
2. Reconnect the (–) negative lead to the
vehicle’s battery. Apply power to the
audio system and play a dynamic music
track.
3. On the source unit, increase the volume
control to 3/4 volume. Slowly increase
the INPUT LEVEL control(s) toward three
o’clock until you hear slight distortion
in the music. Then reduce the INPUT
LEVEL slightly until distortion is no
longer heard.
NOTE: After the source unit is on, blue
LEDs (on the top panel) will light, indicating
the amplifier is on. If not, check the wiring,
especially the remote connection from the
source unit. Also refer to “Troubleshooting”
guide at right.
