Cautions

• This unit is designed for negative ground 12 V DC

operation only.

• Do not get the wires under a screw, or caught in

moving parts (e.g. seat railing).

• Before making connections, turn the car ignition

off to avoid short circuits.

• Connect the yellow and red power input leads

only after all other leads have been connected.

• Run all ground wires to a common ground

point.

• Be sure to insulate any loose unconnected wires

with electrical tape for safety.

• The use of optical instruments with this product

will increase eye hazard.

Notes on the power supply cord (yellow)
• When connecting this unit in combination with

other stereo components, the connected car
circuit’s rating must be higher than the sum of
each component’s fuse.

• When no car circuits are rated high enough,

connect the unit directly to the battery.

• The numbers in the list are keyed to those in the

instructions.

• The bracket 1 is attached to the unit before

shipping. Before mounting the unit, use the

are also necessary if you remove the unit from
your car.

Caution

Handle the bracket 1 carefully to avoid injuring
your fingers.

Note
Before installing, make sure that the catches on both
sides of the bracket 1 are bent inwards 2 mm (

in). If

the catches are straight or bent outwards, the unit

Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and

with adequate power handling capacities to avoid its
damage.

chassis, or connect the terminals of the right speakers
with those of the left speaker.

• Do not connect the ground lead of this unit to the

negative (–) terminal of the speaker.

• Do not attempt to connect the speakers in parallel.
• Connect only passive speakers. Connecting active

speakers (with built-in amplifiers) to the speaker
terminals may damage the unit.

• To avoid a malfunction, do not use the built-in speaker

wires installed in your car if the unit shares a common
negative (–) lead for the right and left speakers.

• Do not connect the unit’s speaker cords to each other.
