For safety....

• Do not raise the volume level too much, as this will block outside sounds, making driving

dangerous.

This unit is designed to operate on 12 V DC, NEGATIVE ground electrical systems.

• To prevent short circuits, we recommend that you disconnect the battery’s negative terminal and

make all electrical connections before installing the unit.

• Cover the unused terminals with insulating tape to prevent them from short circuiting.

• When an extension lead is used, it should be as thick and short as possible; connect it firmly with

insulating tape.

• Be sure to leave an appropriate space between the antenna and the wires of this unit.

• When replacing the fuse, only use a 15 A fuse.

• Do not let foreign objects get inside the unit.

• To keep the heat dissipation mechanism running effectively, wipe the accumulated dust off

periodically.

• Using this subwoofer system with the volume on loud for a long period of time will exhaust the

battery, while the engine is turned off or while the engine is idling.

• This unit becomes very hot. Be careful not to touch the unit not only when using but for a while

after using.

determined by turning the equipment off and on, the user is encouraged to try to correct the

interference by one or more of the following measures:

• Reorient or relocate the receiving antenna.

• Increase the separation between the equipment and receiver.

• Connect the equipment into an outlet on a circuit different from that to which the receiver is

connected.

• Consult the dealer or an experienced radio/TV technician for help.

The power is not on. The sound is disrupted.

• Connect the remote input and power correctly.

• Connect the ground wire correctly to the metal part of the car.

No sound from the speaker.

• Connect the line input or speaker input cord correctly.

CAUTIONS

 Ground wire connection

This unit requires a large amount of electrical

current during loud volume.

Peel off the coating or painting of the metal

part of the car connected to the ground wire

and screw to tighten.

If the current cannot flow smoothly, it will

cause a poor sound quality, power does not

turn on, or the sound will be cut off

momentarily.

When this happens, check the condition of

the ground wire again. If it does not improve,

change the location to connect the ground

wire.

 When connecting to power (accessory or memory power) other than the battery.

A loud volume may cause the illumination of the car stereo to dim and the fuse may blow.

Connect the power cord only to the plus + terminal of the battery.

 Do not cut off the fuse; otherwise, it may be short-circuited, and cause a fire.

 Be sure to connect the "remote input" to the "remote output" of the car stereo or to the ACC

line (power) of the car.

When there is no “remote output”, connect to ACC line (power).

 When the line output of the car stereo exceeds 2V, switch the INPUT ATT. switch to "ON".

 This unit is designed specifically for a DC12V, minus ground vehicle. It cannot be used in a

24V vehicle such as a large truck.

 When remote control is not used, the volume of this unit is fixed at the maximum level.

After connection, reconnect the battery negative terminal and make sure stop lamps and

others can operate normally.
