User manual KENWOOD KAC-X501F

[. . . ] Model KAC-X501F Serial number To prevent injury or fire, take the following precautions: When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with a 8 mm2 (AWG 8) or more to prevent wire deterioration and damage to the wire coating. To prevent a short circuit, never put or leave any metallic objects (such as coins or metal tools) inside the unit. If the unit starts to emit smoke or strange smells, turn off the power immediately and consult your Kenwood dealer. Do not touch the unit during use because the surface of the unit becomes hot and may cause burns if touched. [. . . ] Changes or modifications to this equipment may cause harmful interference unless the modifications are expressly approved in the instruction manual.

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. Be sure to turn the power off before changing the setting of any switch. If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating. Do not remove caps from unconnected wires or connectors to prevent short circuits. 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. Gray/Black Genuine-accessory car stereo (No line output center unit etc. 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. Lead terminal* Terminal cover Battery wire* Protective Fuse* Right speaker Left speaker Remove the cover to access to its controls for adjustment. If you can't find the specified capacity fuse at your store etc. Be sure to connect it with all the systems. The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. [. . . ] The signal that's input from the line input terminal is output. The amplifier can be used as a stereo amplifier. Amplifies the signal input from the left side only. Set to this position and make bridged connections to use as a high-power monaural amplifier. [. . . ]
