• Stop the car before performing any complicated operations.
CAUTIONS AND NOTES
Fuse*
This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems.
JVC recommends consulting a qualified technician for installation.
• This unit uses BTL (Balanced Transformerless) amplifier circuitry, i.e., floating ground system,
so comply with the following:
– Do not connect the “·” terminals of the speakers to each other.
– Do not connect the “·” terminals of the speakers to the metal body or chassis.
• Cover the unused leads with insulating tape to prevent them from short circuiting.
• When an extension lead is used, it should be as thick and short as possible; connect it firmly
with insulating tape.
• Be sure to leave an appropriate space between the antenna (aerial) and the wires of this unit.
• If the fuse blows, first make sure the wires aren’t touching to cause a short circuit then replace
the old fuse with one with the same rating.
• Do not let pebbles, sand or metallic objects get inside the unit.
• To keep the heat dissipation mechanism running effectively, wipe the accumulated dust off
periodically.
• Listening to the tape, radio, CD or digital audio player, etc. with the volume set at a high level
for a long period of time will exhaust the battery, while the engine is turned off or while the
engine is idling.
• This unit becomes very hot. Be careful not to touch the unit not only when using but after using.
DO NOT disassemble the unit since there are no user serviceable parts inside.
To metallic body or chassis
(To an accessory terminal)
Remote turn-on line
Ignition switch
Car battery
JVC car receiver, etc.
Caution
To prevent short circuits while making connections, keep the battery’s negative terminal
disconnected.
• When using a power cord (purchased separately), be sure to place the fuse near the battery as
shown.
• Connect the lead wire (power cord) through which power is supplied directly to the battery’s
“ª” terminal only after all the other connections have been made.
The proper lead wire connected to each POWER terminal is as follows.
• + B and GND: AWG 8 to AWG 4 (The cross section is about 8 mm2 to 21 mm2.)
• REM: AWG 18 to AWG 8 (The cross section is about 0.8 mm2 to 8 mm2.)
a When you use JVC car receiver with a remote lead, connect to the REM terminal on this unit.
b When you connect a unit without a remote lead, connect to the accessory circuit of the car
which is activated by the ignition switch. In this case, noise may occur when the car receiver
is turned on or off. To avoid this noise, do not turn on or off the car receiver itself. You can
turn on or off the car receiver along with the on/off operation of the ignition switch.
INSTALLATION
The following illustration shows a typical installation. However, you should make adjustments
corresponding to your specific car.
• Mount this unit on a firm surface, such as in the
trunk or under the front seat.
• Since heat is generated in the unit, do not
mount it near inflammable objects. In addition,
mount it in an area that will not prevent the unit
from dissipating the heat.
• Do not mount the unit in the places subject to
heat: near a radiator, in a glove compartment or
Onto the trunk floor in insulated areas such as under a car mat that
Under the front seat
will prevent the unit from dissipating heat.
• When mounting the unit under the front seat,
make sure that adjusting the seat position will
not catch any wire of the unit.

TERMINAL CONNECTIONS
When making terminal connections, properly fix each terminal with the provided screw by turning
it as illustrated.
• Use ring terminals (not provided) for secure connection.
Notes
• Make sure the screw is fixed in place to prevent disconnections.
• Avoid over-tightening as it may cause the damage to the screw or its
head slot.
ı Install the unit
Provided screw
φ 4 × 20 mm (13/16 in.)
SPEAKER SYSTEMS
• When mounting this unit, be sure to use the
provided screws.
• If any other screws are used, there is a risk of
loosening the unit or damaging the parts under
the car floor.
• Before drilling holes in the trunk to install the
unit, make sure that there is a sufficient space
under the trunk so that you do not drill holes in
the fuel tank, etc.
Notes
• Be sure not to connect the “·” terminals of the speakers to a common point.
• If the same lead is used for both left/right or front/rear speaker wirings, this unit cannot be used.
Always use the independent leads for each speaker. In this case, redo the wirings.
• Use the speakers with an impedance of 2 Ω to 8 Ω (4 Ω to 8 Ω: when used in Bridge Mode).
• Use the speakers which have sufficient capacity to the unit.
The proper lead connected to each SPEAKER OUTPUT terminal is as follows.
KS-AX3104/KS-AX3102: AWG 18 to AWG 12 (The cross section is about 0.8 mm2 to 3.3 mm2).
KS-AX3101D: AWG 18 to AWG 8 (The cross section is about 0.8 mm2 to 8 mm2).

SAFETY INSTRUCTIONS
“SOME DOS AND DON’TS ON THE SAFE USE OF EQUIPMENT”
Dear Customer,
This apparatus is in conformance with the valid European directives and
standards regarding electromagnetic compatibility and electrical safety.
European representative of Victor Company of Japan, Limited is:
JVC Technical Services Europe GmbH
Postfach 10 05 04
61145 Friedberg
Germany
This equipment has been designed and manufactured to meet international safety standards but, like any electrical
equipment, care must be taken if you are to obtain the best results and safety is to be assured.
DO read the operating instructions before you attempt to use the equipment.
DO ensure that all electrical connections (including the mains plug, extension leads and interconnections between
pieces of equipment) are properly made and in accordance with the manufacturer’s instructions. Switch off and
withdraw the mains plug when making or changing connections.
DO consult your dealer if you are ever in doubt about the installation, operation or safety of your equipment.
DO be careful with glass panels or doors on equipment.
Information for Users on Disposal of Old Equipment and Batteries
