ENGLISH  
When you use more than one KS-AR8000 series amplifier, you can pile up to three of  
them using the provided brackets and hex screws in two ways, X or Y.  
1 Attach the provided spacers to the bottom of the amplifier (2 and 3).

Thank you for purchasing an ARSENAL product. Please read all instructions carefully before  
operation, to ensure your complete understanding and to obtain the best possible performance  
from the unit.  
2 Fix the amplifiers on both sides with the brackets (I) as illustrated.  
• Be sure to mount the lowest amplifier (1) as illustrated on  
.
• Before piling amplifiers as X, first make the connections for the power supply (see  
For safety....  
“POWER SUPPLY” below) and speakers (see “SPEAKER CONNECTIONS” on page 2).  
Do not raise the volume level too much, as this will block outside sounds, making driving dangerous.

CAUTIONS AND NOTES  
Spacer  
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 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.  
• When replacing the fuse, use a 30 A fuse for KS-AR8004D or a 25 A fuse for KS-AR8002D.  
• 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.  
POWER SUPPLY  
• 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.  
*Not included with this unit.  
DO NOT disassemble the units since there are no user serviceable parts inside.

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.  
JVC car receiver, etc.  
Car battery  
CAUTION  
Mount this unit on a firm surface, such as in the trunk or under the front seat.  
To prevent short circuits while making connections, keep the battery’s negative terminal  
disconnected.  
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.  
1 Remote turn-on line (not included with this unit)  
a When you use a JVC car receiver with a remote lead, connect to the remote lead.  
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.  
2 Ground lead (not included with this unit)  
When mounting the unit under the front seat, make sure that adjusting the seat position  
will not catch any wire of the unit.  
3 Power cord (not included with this unit)  
When using a power cord, be sure to add the appropriate fuse near the battery as shown.  
For KS-AR8004D: 40 A  
For KS-AR8002D: 30 A  
Connect to the battery’s “ª” terminal only after all the other connections have been made.  
Under the front seat  
Onto the trunk floor  
Note  
If the Status lamp (see “CONTROLS” on page 3) lights in red, it indicates incorrect speaker  
wiring or connections. In this case, see “TROUBLESHOOTING” on page 3. Be sure to correct the  
speaker wiring and other connections.  
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 parts inside it.  
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.  
TERMINAL CONNECTIONS  
To detach and rotate the Logo Plate, use the provided hex wrench (3 mm).  
The appropriate wire gauge for each terminal is as follows.  
Screw (Dia. 3/16 inch (4 mm)  
× 13/16 inch (20 mm))  
Bracket (L)  
• POWER terminals:  
+ B and GND: AWG 8 to AWG 4 (The cross section is about 8 mm2 to 21 mm2.)

• SPEAKER OUTPUT terminals:  
Hex Screw (M4 × 7/16 inch (10 mm))

If you have any questions regarding the thickness of the power cord, etc., consult your nearest  
JVC car audio dealer.  
Logo Plate (detachable)  
1 Peel off the insulating vinyl cover of a lead to expose the conductor  
inside.  
The exposed conductor should be 5/16 inch (7 mm) to 7/16 inch  
(10 mm) long.  
– If shorter, it may cause poor conductivity.  
– If longer, it may cause a short circuit.  
2 Loosen the hex screw in a terminal with the provided hex wrench  
Bracket (L)  
and insert the conductor into the terminal.  
Use the appropriate hex wrench for each terminal.

SPEAKER SYSTEMS  
Make sure to comply with the following notes:  
For KS-AR8004D:  
• 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 independent leads for each speaker. In this case, redo the wiring.  
• Use speakers with an impedance of 2 to 8 (4 to 8 : when used in Bridge Mode).  
• Use speakers which have sufficient capacity for the unit.  
When you connect 4 speakers to the unit, down mixed signals (front and rear) are emitted  
through the PRE OUT jacks.  
For KS-AR8002D:  
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.  
Connect the Line Output from the receiver to the INPUT jacks on this unit using RCA pin  
cords (not included with this unit).  
Before connecting:  
• Be sure to adjust the CROSSOVER filter switch as illustrated on the following diagrams. (See  
also “CONTROLS” on page 3.)  
• 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.  
Note  
Do not adjust the CROSSOVER filter switch while the unit is turned on.
