
Since this unit deals with a high power, large current will flow and the wiring or power cord is high
importance.
 Connect the red wire directly to the (+) terminal of the battery using the cord with a fuse holder
supplied.
 Connect the black wire tightly to an appropriate screw on the metal part of car after removing paint
for proper grounding. Be sure to use the screw not bring danger for driving.

Proper connection will provide clear sound.
 Connect the orange wire to a switched power cord of the car stereo to be connected to this unit will
control the unit power on/off with the car stereo' s

The switched power cord may be obtained an auto antenna cord of the car stereo.
 This unit can be connected to any car stereo with high level outputs, common or separated ground
outputs.
 Separated ground car stereo connection;-connect car stereo speaker output cables to the high level
input connector (+) and (-), right and left polarity.
 Common ground car stereo connection;-connect car stereo speakers negative output cable to the
high level input connector to the two signs (-) and the remaining cables to (+) right and left..
