If you have any questions or require information regarding installation kits, consult your JVC Car audio

CAUTIONS AND NOTES
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.

• 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
in insulated areas such as under a car mat that 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.

• 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.
• Attach the side cover using the provided screws
after connected speaker and power supply cables
and installed the unit.

POWER SUPPLY

KS-AX5104
KS-AX5101D
To metallic body or chassis*
...2
Remote turn-on line*
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 mm
• REM: AWG 18 to AWG 8 (The cross section is about 0.8 mm
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.
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.

SPEAKER SYSTEMS

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-AX5104/KS-AX5102: AWG 18 to AWG 12 (The cross section is about 0.8 mm
KS-AX5101D: AWG 18 to AWG 8 (The cross section is about 0.8 mm

SPEAKER CONNECTIONS

Connection varies depending on the number of the speakers used in your car. Select the appropriate
connection referring to the following diagrams.
Notes
• Securely connect all the parts. If the connections are loose, due to contact resistance etc., heat will
break out and may cause an accident.
• Run the connection leads under the car mats to prevent accidental disconnections.
Å When your receiver is equipped with line output.
ı When your receiver is NOT equipped with line output.
KS-AX5104
• Connect each lead of the speaker input connector to a speaker positive lead or negative lead of the
receiver.
