Accessories/ Installation Procedure  
Accessories  
¤
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.  
If your car is not prepared for this special connection-  
system, consult your Kenwood dealer.  
Only use antenna conversion adapters (ISO-JASO) when the  
antenna cord has an ISO plug.  
Make sure that all wire connections are securely made by  
inserting jacks until they lock completely.  
If your vehicle’s ignition does not have an ACC position, or  
if the ignition wire is connected to a power source with  
constant voltage such as a battery wire, the power will not  
be linked with the ignition (i.e., it will not turn on and off  
along with the ignition). If you want to link the unit’s power  
with the ignition, connect the ignition wire to a power  
source that can be turned on and off with the ignition key.  
If the fuse blows, first make sure that the wires have not  
caused a short circuit, then replace the old fuse with one  
with the same rating.  
Insulate unconnected wires with vinyl tape or other similar  
material. To prevent short circuits, also 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 receive damage or fail  
to work if you share the - wires and/or ground them to  
any metal part in the car.

Installation Procedure  
1. To prevent short circuits, remove the key from the  
ignition and disconnect the - terminal of the  
battery.  
2. Make the proper input and output wire  
connections for each unit.  
3. Connect the wire on the wiring harness.  
4. Take Connector B on the wiring harness and  
connect it to the speaker connector in your vehicle.  
5. Take Connector A on the wiring harness and  
connect it to the external power connector on your  
vehicle.  
6. Connect the wiring harness connector to the unit.  
7. Install the unit in your car.  
After the unit is installed, check whether the brake lamps,  
indicators, wipers, etc. on the car are working properly.  
If the console has a lid, make sure to install the unit so  
that the faceplate does not hit the lid when closing and  
opening.  
Mount the unit so that the mounting angle is 30° or less.  
8. Reconnect the - terminal of the battery.  
9. Press the reset button.
