	ENGLISH

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 unit.

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.

CAUTIONS AND NOTES

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 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 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.

INSTALLATION

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.

AMount 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.

BWhen 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).

CWhen 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).

TERMINAL CONNECTIONS

When making the terminal connections…

1 Peel the insulating vinyl cover of a cord 7 mm (5/16 inch) to 10 mm (7/16 inch) long and expose the inside conductor.

2 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.

Note

•The exposed conductor should be 7 mm (5/16 inch) to 10 mm (7/16 inch) long.

–If shorter, it may cause a poor conductivity.

–If longer, it may cause a short circuit.

• Use a proper hex wrench for each terminal.

– 4 mm: +B terminal and GND terminal

– 3 mm: REM terminal and speaker terminals

POWER SUPPLY

* Not included with this unit.

40 A Fuse

To metallic body or chassis

(To an accessory terminal)

		Remote turn-on line
Car battery	Ignition switch	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 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 mm2 to 21 mm2.)

•REM: AWG 18 to AWG 8 (The cross section is about 0.8 mm2 to 8 mm2.)

•If you have any questions regarding the thickness of the power cord, etc., consult your nearest JVC car audio dealer.

aWhen 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.

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.

SPEAKER SYSTEMS

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 wirings.

•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 mm2 to 8 mm2.)

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.

SPEAKER CONNECTIONS

Connection varies depending on the number of the speakers used in your car. Select the appropriate connection referring to the following diagrams.

Before connecting: Securely connect all the parts. If the connections are loose, due to contact resistance etc., heat will break out and may cause an accident. Secure and cover the cords with insulating tape and run them under the car mats.

å When your receiver is equipped with Line Output, connect the Line Output (through the receiver) to the INPUT jacks on this unit.

∫When your receiver is NOT equipped with Line Output, connect the provided speaker input connector (through the receiver) to the HIGH INPUT terminal on this unit.
