[. . . ] The ground lead is not securely connected. This unit can be used as a bridging amplifier with a maximum output of 222 W. Direct connection can be made with the speaker output of your car audio if it is not equipped with the line output (High level input connection). [. . . ] Use speakers with an impedance of 2 to 8 (4 to 8 when used as a bridging amplifier). Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may damage the active speakers. Avoid installing the unit in areas subject to: -- high temperatures such as from direct sunlight or hot air from the heater -- rain or moisture -- dust or dirt. If your car is parked in direct sunlight and there is a considerable rise in temperature inside the car, allow the unit to cool down before use. When installing the unit horizontally, be sure not to cover the fins with the floor carpet etc. If this unit is placed too close to the car radio or antenna, interference may occur. In this case, relocate the amplifier away from the car radio or antenna. If no power is being supplied to the master unit, check the connections. This power amplifier employs a protection circuit to protect the transistors and speakers if the amplifier malfunctions. Do not attempt to test the protection circuits by covering the heat sink or connecting improper loads. Do not use the unit on a weak battery as its optimum performance depends on a good power supply. For safety reasons, keep your car audio volume moderate so that you can still hear sounds outside your car. If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.
