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.
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 Trans-formerless) 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 (aerial) and the wires of this unit.
• When replacing the fuse, only use a 25 A fuse for KS-AX3500 and 30 A fuse for KS-AX3300.
• 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 MD, etc. with the volume on loud for a long period of time will
exhaust the battery, while the engine is turned off or while the engine is idling.
DO NOT disassemble the units since there are no user serviceable parts inside.

POWER SUPPLY
CAUTION
To prevent short circuits while making connections, keep the battery's negative terminal
disconnected.
• When using a power cord, be sure to place the 30 A fuse near the battery as shown.
• Connect the lead wire (purchased separately) through which power is supplied directly to the
battery's "ª" terminal only after all the other connections have been made.
The lead wire connected to the + B terminal of this unit should have a cross-section of more
than 5 mm
2
. Be sure to use a ring terminal (optional) for secure connection.
• If you have any questions regarding the thickness of the power cord, etc., consult your nearest
"JVC IN-CAR ENTERTAINMENT" car audio dealer.
When connecting 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 you use JVC car receiver with a remote lead (∫), connect to the REM terminal on this unit.
If the POWER/PROTECTOR lamp lights in red, it indicates incorrect speaker wiring or
connections. In normal status, the POWER/PROTECTOR lamp lights in green. Make sure to
correct speaker wiring and other connections.

fi lter) switch. The low frequency signals are not applied to the left/
right speaker when a subwoofer is connected.
ı Input LEVEL controller
The input level can be adjusted with this control when this unit is connected to other source
equipments. Turn it in the clockwise direction when the output level of the car audio seems low.
SPEAKER SYSTEMS
