Safety precautions

WARNING

To prevent injury or fire, take the following precautions:

• Mounting and wiring this product requires skills and experience. For safety’s sake, leave the mounting and wiring work to professionals.

• When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with the range of 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.

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.

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.

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

The protection function is activated in the following situations:

This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur.

When the protection function is triggered, the power indicator goes off and the amplifier stops operating.

• When a speaker wire may be short-circuited.

• When a speaker output contacts ground.

• When the unit malfunctions and a DC signal is sent to the speaker output.

• When the internal temperature is high and unit won’t operate.

7 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. (Use a power wiring cord with the range of 5 mm (AWG 10) or more.)

• 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.

7 Speaker selection

• Using speakers with smaller input ratings than the amplifier’s output power would result in smoke generation or equipment failure.

• 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.

6 Cooling fan 7 FILTER FREQUENCY control

(A.ch/B.ch)

Sets the cutoff frequency when the “FILTER” switch is set to “HPF” or “LPF”.

8 FILTER switch (A.ch/B.ch)

This switch allows to apply high-pass or low-pass filtering to the speaker outputs.

• HPF (High-Pass Filter) position:

The filter outputs the band of higher frequencies than the frequency set with the “FILTER FREQUENCY” control.

• OFF position:

The entire bandwidth is output without filtering.

• LPF (Low-Pass Filter) position:

The filter outputs the band of lower frequencies than the frequency set with

the “FILTER FREQUENCY” control.

9 INPUT SENSITIVITY control (A.ch/B.ch)

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

NOTE

For the pre-output level, refer to the <Specifications> in the instruction manual of the center unit. The entire bandwidth is output without filtering.

0 BASS BOOST switch (B.ch)
