2WARNING

To prevent injury or fire, take the following precautions:

???When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 5 mm?? (AWG 10) or more to prevent wire deterioration and damage to the wire coating.

???To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit.

???If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer.

???Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched.

2 CAUTION

To prevent damage to the machine, take the following precautions:

???Be sure the unit is connected to a 12V DC power supply with a negative ground connection.

???Do not open the top or bottom covers of the unit.

???Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing.

???When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction.

???To prevent a short circuit when replacing a fuse, first disconnect the wiring harness.

NOTE

???If you experience problems during installation, consult your Kenwood dealer.

???If the unit does not seem to be working right, consult your Kenwood dealer.

This product is not installed by the manufacturer of a vehicle on the production line, nor by the professional importer of a vehicle into an EU Member State.

Information on Disposal of Old Electrical and Electronic Equipment (applicable for EU countries that have adopted separate waste collection systems)

Products with the symbol (crossed-out wheeled bin) cannot be disposed as household waste.

Old electrical and electronic equipment should be recycled at a facility capable of handling these items and their waste byproducts. Contact your local authority for details in locating a recycle facility nearest to you. Proper recycling and waste disposal will help conserve resources whilst preventing detrimental effects on our health and the environment.

Cleaning the unit

If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth.

2 CAUTION

Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off.

To prevent battery rise

When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. Use it after starting the engine.

Protection function

There is a Protection function installed in the unit to protect the unit and speakers from various problems. When Protection operates, the indicator informs you of the condition. (Refer to page 5)

This switch allow filtering of the speaker output signals.

???OFF position:

The original sound without filtering is output.

???LPF (Low-Pass Filter) position:

Only frequencies of 80 Hz or lower are output. (Frequencies above 80 Hz are cut.)

The speaker output is automatically turned monaural (L+R) and the bass boost function is activated.

2INPUT SENSITIVITY control

Set this control according to the pre-output level of the center unit connected with this unit, or

to the maximum power output of the genuine- accessory car stereo.

Use the diagram on the right as a guide.

NOTE

For the pre-output level or the maximum power output, refer to the <Specifications> in the instruction manual of the center unit.

3Power indicator

When the power is turned on, the Power indicator lights.

If the Power indicator does not light when the power is turned on, the protection function may be activated. Check whether there is any indication of trouble.

8Speaker output terminals

???Stereo Connections:

When you wish to use the unit as a stereo amplifier, stereo connections are used.

The speakers to be connected should have an impedance of 2?? or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2?? or greater for each channel.

???Bridged Connections:

When you wish to use the unit as a high-output monaural amplifier, bridged connections are used. (Make connections to the LEFT channel 9 and the RIGHT channel ?? SPEAKER OUTPUT terminals.)

The speakers to be connected should have an impedance of 4?? or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4?? or greater.

2 CAUTION

The rated input of the speakers should be no less than the maximum output of the amplifier. Otherwise malfunction may result.

9 LINE IN terminal

0 Speaker level input terminals

NOTE

???The genuine-accessory car stereo shall have a maximum power output of no more than 40 W.

???Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage.

???Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage.

???Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this

connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF.

??? Installation procedure

Since there are large variety of settings and connections possible according to applications, read the instruction manual well to select the proper setting and connection.

1.Remove the ignition key and disconnect the negative - terminal of the battery to prevent short circuits.

2.Set the unit according to the intended usage.

3.Connect the input and output wires of the units.

4.Connect the speaker wires.

5.Connect the power wire, power control wire and grounding wire following this order.

6.Install the unit in the car.

7.Connect the negative - terminal of the battery.

2WARNING

To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery???s positive terminal.

2CAUTION

???If sound is not output normally, immediately turn power off and check connections.

???Be sure to turn the power off before changing the setting of any switch.

???If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating.

???Check that no unconnected wires or connectors are touching the car body. Do not remove caps from unconnected wires or connectors to prevent short circuits.

???Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail.

???After installation, check that the brake lamps, winkers, and wipers work properly.

??? Wiring

???Take the battery wire for this unit directly from the battery. If it's connected to the vehicle???s wiring harness, it can cause blown fuses etc.

???If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire.

???Do not allow the wire to directly contact the edge of the iron plate by using Grommets.

???Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery???s negative - terminal. Do not turn the power on if the ground wire is not connected.

???Be sure to install a protective fuse in the power cord near the battery. The protective fuse should be the same capacity as the unit???s fuse capacity or somewhat larger.

???For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit???s fuse capacity. (Use a power wiring cord with a diameter of 5 mm?? (AWG 10) or greater.)

???When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier.

??? Speaker selection

???The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage.

???The impedance of the speakers that are going to be connected should be 2?? or greater (for stereo connections), or 4?? or greater (for bridged

connections). When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier.
