Thank you for purchasing a JVC product. Please read all instructions carefully before operation, to
ensure your complete understanding and to obtain the best possible performance from the unit.
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 30 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.
