Thank you for purchasing a JVC product. Please read all instructions carefully before operation,
to ensure your complete understanding and to obtain the best possible performance from the
KS-AR9001D is designed to be connected to subwoofers.
For safety....
• Do not raise the volume level too much, as this will block outside sounds, making driving dangerous.
• Stop the car before performing any complicated operations.
This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems.
• This unit uses BTL (Balanced Transformerless) amplifier circuitry, i.e., floating ground system,
so please 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 terminals 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 and the wires of this unit.
• For KS-AR9004: When replacing the fuse, only use a 40 A fuse.
For KS-AR9001D: When replacing the fuse, only use a 30 A fuse.
• 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
• 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 for a while
after using.
DO NOT disassemble the units since there are no user serviceable parts inside.
For Customer Use:
Enter below the Model No. and Serial No. which are located on the top or bottom of the
cabinet. Retain this information for future reference.

The following illustration shows a typical installation. However, you should make adjustments
corresponding to your specific car. If you have any questions or require information regarding
installation kits, consult your JVC car audio dealer or a company supplying the kits.
A Mount this unit on a firm surface, such as in the trunk room 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.
B When mounting this unit, be sure to use the provided screws. If any other screws are used,
the unit may not be fixed firmly or parts inside the unit may be damaged.
• Before drilling holes in the trunk to install the unit, make sure to have a sufficient space
under the trunk so that you do not drill holes in the fuel tank, etc.
• To detach and rotate the Logo Plate, use the provided hex wrench (2.5 mm).
C When you use more than one KS-AR9000 series amplifier, you can pile them up to three with
provided brackets, screws and washers in two ways, X or Y. Be sure to mount the lowest
amplifier (1) primarily following B.
• Before piling amplifiers, attach the provided spacers to the "+" marks on the bottom of the
amplifiers 2 and 3.
• Before piling amplifiers as X, first make the connections for the power supply (see "POWER
SUPPLY") and speakers (see "SPEAKER CONNECTIONS" on page 2).

When making the terminal connections...
Peel the insulating vinyl cover of a cord 7 mm (
inch) long and expose the inside conductor.
Loosen the hex screw in a terminal with a provided hex wrench
and insert the conductor into the terminal. Then fix the hex screw
again to secure the conductor.
• The exposed conductor should be 7 mm (
– If shorter, it may cause a poor conductivity.
– If longer, it may cause a short circuit.
• Use a proper hex wrench for each terminal.

To prevent short circuits while making connections, keep the battery's negative terminal
• When using a power cord (purchased separately), be sure to place the 40 A 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
• If you have any questions regarding the thickness of the power cord, etc., consult your nearest
JVC car audio dealer.
a When you use JVC car receiver with a remote lead, connect to the REM terminal on this
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.
If the POWER/PROTECTOR lamp lights in red, it indicates incorrect speaker wiring or
connections (see "TROUBLESHOOTING" on page 3). Make sure to correct speaker wiring and
other connections.
Make sure to comply with the following notes:
• Be sure not to connect the "·" terminals of the speakers to a common point.
• If the ground wire is common to both left/right and front/rear speaker wirings, this unit cannot be
used. Always use the independent lead wires for the speakers to be used. In this case, redo the
• For KS-AR9004: Use the speakers with an impedance of 2 Ω to 8 Ω (4 Ω to 8 Ω when used in
Bridge Mode).
For KS-AR9001D: Use the speakers with an impedance of 1 Ω to 8 Ω.
• Use the speakers which have sufficient capacity to the unit.
The proper lead wire connected to each SPEAKER OUTPUT terminal is as follows.
AWG 18 to AWG 8 (The cross section is about 0.8 mm
For KS-AR9004: When you connect 4 speakers to the unit, down mixed signals (front and rear)
are emitted through the PRE OUT jacks.
For KS-AR9001D: Incoming signals are emitted through the PRE OUT jacks.
