Safety precautions

 WARNING

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 mm2 (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.

•  Mounting and wiring this product requires skills and 

experience. For safety’s sake, leave the mounting 

and wiring work to professionals.

 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 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.

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 mm2 (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 input power of the speakers that are going to 

be connected should be greater than the 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.

•  Use speakers that have an impedance of 2Ω or 

greater. 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.

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 from running out

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.
