CAUTIONS AND NOTES

This unit is designed to operate on 12 V DC NEGATIVE ground electrical systems

JVC recommends consulting a qualified technician for installation.

- 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 leads 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 (aerial) and the wires of this unit.

- If the fuse blows first make sure the wires aren’t touching to cause a short circuit then replace

the old fuse with one with the same rating.

• 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 after using.

DO NOT disassemble the unit since there are no user serviceable parts inside.

• Mount this unit on a firm surface such as in the

trunk 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.

POWER SUPPLY

FUSE

POWER

To metallic body or chassis (To an accessory terminal)

Fuse*

Car battery

Ignition switch

JVC car receiver etc.

Remote turn-on line

* Not Supplied 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 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 to 21 mm

• REM: AWG 18 to AWG 8 (The cross section is about 0.8 mm

to 8 mm

When you use JVC car receiver with a remote lead connect to the REM terminal on this unit.

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.

TERMINAL CONNECTIONS

When making terminal connections properly fix each terminal with the provided screw by turning it as illustrated. • Use ring terminals (not provided) for secure connection.

notes

• Make sure the screw is fixed in place to prevent disconnections. • Avoid over-tightening as it may cause the damage to the screw or its

head slot.

SPEAKER SYSTEMS

notes

• 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 the independent leads for each speaker In this case redo the wirings.

• Use the speakers with an impedance of 2

Ω to 8 Ω (4 Ω to 8 Ω: when used in Bridge Mode).

• Use the speakers which have sufficient capacity to the unit

The proper lead connected to each SPEAKER OUTPUT terminal is as follows AWG 18 to AWG 12 (The cross section is about 0.8 mm to 3.3 mm
