Connection example

• This unit is designed for negative ground 12 V DC operation only.

• Before making connections, disconnect the ground terminal of the car battery to avoid short circuits.

• Connect the yellow and red power input leads only after all other leads have been connected.

• Be sure to connect the red power input lead to the positive 12 V power terminal which is energized

when the ignition key is in the accessory position.

• Run all ground wires to a common ground point.

• Connect the yellow cord to a free car circuit rated higher than the unit’s fuse rating.

If you connect this unit in series with other stereo components, the car circuit they are connected to must be rated higher than the sum of the individual component’s fuse rating. If there are no car circuits rated as high as the unit’s fuse rating, connect the unit directly to the battery. If no car circuits are available for connecting this unit, connect the unit to a car circuit rated higher than the unit’s fuse rating in such a way that if the unit blows its fuse, no other circuits will be cut off.
