• Use this unit in other than the following

conditions could result in fire or malfunction.

— Vehicles with a 12-volt battery and negative

grounding.

— Speakers with 50 W (output value) and 4 ohm

to 8 ohm (impedance value).

• To prevent short-circuit, overheating or

malfunction, be sure to follow the directions

below.

— Disconnect the negative terminal of the

battery before installation.

— Secure the wiring with cable clamps or

adhesive tape. To protect the wiring, wrap

adhesive tape around them where they lie

against metal parts.

— Place all cables away from moving parts, such

as gear shift and seat rails.

— Place all cables away from hot places, such as

near the heater outlet.

— Do not pass the yellow cable through a hole

into the engine compartment to connect to a

battery.

— Cover any disconnected cable connectors with

insulating tape.

— Do not shorten any cables.

— Never cut the insulation of the power cable of

this unit in order to share the power to other

equipment. Current capacity of the cable is

limited.

— Use a fuse of the rating prescribed.

— Never wire the speaker negative cable directly

to ground.

— Never band together multiple speaker’s

negative cables.

• Control signal is output through blue/white cable

when this unit is powered on. Connect it to an

external power amp’s system remote control or

the vehicle’s auto-antenna relay control terminal

(max. 300 mA, 12 V DC). If the vehicle is equipped

with a glass antenna, connect it to the antenna

booster power supply terminal.

• Never connect blue/white cable to external power

amp’s power terminal. Also, never connect

it to the power terminal of the auto antenna.

Otherwise, battery drain or malfunction may

result.

• Black cable is ground. This cable and other

product’s ground cable (especially, high-current

products such as power amp) must be wired

separately. Otherwise, fire or malfunction may

result if they are accidentally detached.
