Installation Procedure
To prevent short circuits, remove the key from the ignition and disconnect the terminal of the battery.
Make the proper input and output wire connections for each unit.
Connect the wire on the wiring harness.
Take Connector B on the wiring harness and connect it to the speaker connector in your vehicle.
Take Connector A on the wiring harness and connect it to the external power connector on your vehicle.
Connect the wiring harness connector to the unit.
Install the unit in your car.
Reconnect the terminal of the battery.
Press the reset button.
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. 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.
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.
Use a commercially available conversion connector if the connector does not fit in the vehicle connector.
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.
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.
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.
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.
