Hide thumbs


KS - AR7501D / KS - AR7001
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.
This unit 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) amplifi er circuitry, i.e., fl oating 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 fi rmly
with insulating tape.
• Be sure to leave an appropriate space between the antenna and the wires of this unit.
• 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.

The following illustration shows a typical installation. However, you should make adjustments
corresponding to your specifi c 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 fi rm surface, such as in the trunk room or under the front seat.
• Since heat is generated in the unit, do not mount it near infl ammable 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
• 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,
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 suffi cient
space under the trunk so that you do not drill holes in the fuel tank, etc.
• Detach the control cover on the unit before mounting (see "CONTROLS" on page 3).
• To detach and rotate the Logo Plate 180 degrees, use the provided hex wrench (3 mm).
C When you use more than one KS-AR7000 series' amplifi er, 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
amplifi er (1) primarily following B.
• Before piling amplifi ers, attach the provided spacers to "+" on the bottom of the amplifi ers
2 and 3.
• Fix the amplifi ers on both sides with proper brackets as illustrated. Brackets (L) are used
only for the amplifi er 3.
• Before piling amplifi ers as X, fi rst make the connections for the power supply (see
"POWER SUPPLY") and speakers (see "SPEAKER CONNECTIONS" on page 2).
• It is recommended to pile amplifi ers as X so that you can easily operate the controllers on
each amplifi er.

When making the terminal connections...
Peel the insulating vinyl cover of a cord
inch (10 mm) 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 fi x the hex screw
again to secure the conductor.
• The exposed conductor should be
– 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
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
• Use the speakers with an impedance of 1 Ω to 8 Ω for KS-AR7501D or 2 Ω to 8 Ω for
• Use the speakers which have suffi cient capacity to the unit.
