•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.
