Before making any connections ensure that the electric equipment of your vehicle is 12 V DC with negative ground.
Disconnect the negative cable from the battery before installation to reduce the risk of unit damage and avoid short circuits during connection.
Ensure that the colored wires are connected according to the diagram. Wrong connection may cause unit failure or malfunctions or damage the electric equipment of the vehicle.
Ensure that the negative speaker cable is connected to the negative speaker terminals. Never connect the “-“ speaker wire to the vehicle ground. Do not obstruct the unit ventilation openings and the radiator area, in order to provide sufficient ventilation and reduce the risk of fire. It is not allowed to connect the unit directly to the car battery, i.e. not via the ignition switch, as this will lead to increased battery depletion during vehicle standstill.
The unit is designed for use in vehicle electric systems with the negative battery pole connected to the metal vehicle body (ground).
If the unit is turned on, do not allow shorting the speaker cables between themselves and to the vehicle body. This may cause amplifier overload or damage.
Turn the unit on when not in use (disconnect it from the power supply if it is not operated for a prolonged time).
Do not install the unit in locations where it can:
Prevent the proper operation of the steering wheel or gearshift lever, as this can be the cause of a traffic accident;

Do not attempt to operate the unit while driving the car. Doing so can be the cause of a traffic accident. If You have to operate the unit while driving, keep Your eyes on the road as failure to do so can be cause of a traffic accident.
When listening to audio while driving set the volume to such a level as not to prevent the driver from hearing everything that is happening around the car.
Do not operate the unit while the car is driving if this can distract the driver’s attention.
Do not expose the unit to drastic temperature changes. This may cause condensation to form inside the unit and lead to damage. If condensate should form inside the unit, wait for 1 hour for the moisture to evaporate. No condensation on unit components should be allowed. Avoid operating the unit in dusty environments.
