Take the time to read through this instruction manual. Familiarity with installation and operation procedures will help you obtain the best performance from your new power amplifier.
For your records
General
Record the serial number, found on the back of the unit, in the spaces designated on the warranty card, and in the space provided below. [. . . ] · If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating. · Check that no unconnected cables or connectors are touching the car body. Do not remove caps from unconnected cables or connectors to prevent short circuits. · Connect the speaker wires to appropriate speaker connectors separately. Sharing the negative wire of the speaker or grounding speaker wires to the metal body of the car can cause this unit to fail. · After installation, check that the brake lamps, winkers, and wipers work properly.
s Speaker Selection
· The rated input power of the speakers that are going to be connected should be greater than the maximum output power (in Watts) of the amplifier. Use of speakers having input power ratings that are less than the output power of the amplifier will cause smoke to be emitted as well as damage. · The impedance of the speakers that are going to be connected should be 2 or greater (for stereo connections), or 4 or greater (for bridged connections). When more than one set of speakers are going to be used, calculate the combined impedance of the speakers and then connect suitable speakers to the amplifier. 4 4 4 4
s Speaker level input terminals ($)
· The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. · Do not connect the speaker output leads from a power amplifier (Optional) to the speaker level input terminals of this unit, for this may cause malfunction or damage. · Do not connect cables and leads to both RCA cable input jacks and the speaker level input terminals simultaneously, for this may cause malfunction or damage. · Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, shock noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF.
· If you experience problems during installation, consult your Kenwood dealer. · If the unit does not seem to be working right, consult your Kenwood dealer.
