Cautions

• This unit is designed for negative earth 12 V DC

operation only.

• Do not get the leads 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 earth leads to a common earth point.
• Be sure to insulate any loose unconnected leads

with electrical tape for safety.

Notes on the power supply lead (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.

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

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.

leads 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 leads to each other.
