Accessories/Installation Procedure  
If you use the wrong screws, you could damage the unit.  
If the power is not turned ON (“PROTECT” is displayed),  
the speaker wire may have a short-circuit or touched the  
chassis of the vehicle and the protection function may  
have been activated. Therefore, the speaker wire should be  
checked.  
Accessories  
1
If your car’s ignition does not have an ACC position, connect  
the ignition wires to a power source that can be turned on  
and off with the ignition key. If you connect the ignition  
wire to a power source with a constant voltage supply, as  
with battery wires, the battery may die.  
..........1  
2
If the console has a lid, make sure to install the unit so that  
the faceplate will not hit the lid when closing and opening.  
If the fuse blows, first make sure the wires aren’t touching  
to cause a short circuit, then replace the old fuse with one  
with the same rating.  
..........2  
3
Insulate unconnected wires with vinyl tape or other similar  
material. To prevent a short circuit, do not remove the caps  
on the ends of the unconnected wires or the terminals.  
Connect the speaker wires correctly to the terminals to  
which they correspond. The unit may be damaged or fail to  
work if you share the - wires or ground them to any metal  
part in the car.  
When only two speakers are being connected to the  
system, connect the connectors either to both the front  
output terminals or to both the rear output terminals (do  
not mix front and rear). For example, if you connect the +  
connector of the left speaker to a front output terminal, do  
not connect the - connector to a rear output terminal.  
After the unit is installed, check whether the brake lamps,  
blinkers, wipers, etc. on the car are working properly.  
Mount the unit so that the mounting angle is 30° or less.  
..........4

..........4  
Installation Procedure  
1. To prevent a short circuit, remove the key from the  
ignition and disconnect the - battery.  
2. Make the proper input and output wire  
connections for each unit.  
3. Connect the speaker wires of the wiring harness.  
4. Connect the wiring harness wires in the following  
order: ground, battery, ignition.  
5. Connect the wiring harness connector to the unit.  
6. Install the unit in your car.  
7. Reconnect the - battery.  
8. Press the reset button.  
2WARNING  
If you connect the ignition wire (red) and the battery wire  
(yellow) to the car chassis (ground), you may cause a short  
circuit, that in turn may start a fire. Always connect those  
wires to the power source running through the fuse box.  
¤
Mounting and wiring this product requires skills and  
experience. For safety’s sake, leave the mounting and wiring  
work to professionals.  
Make sure to ground the unit to a negative 12V DC power  
supply.  
Do not install the unit in a spot exposed to direct sunlight  
or excessive heat or humidity. Also avoid places with too  
much dust or the possibility of water splashing.  
Do not use your own screws. Use only the screws provided.
