User manual KENWOOD KAC-629S

[. . . ] · Connect the speaker wire again so that it is not pinched by anything. · Set switches properly by referring to "System examples". The output level is too small (or too large). (The sound is distorted. ) The input sensitivity adjusting control is not set to the correct position. · The speakers wire are connected with wrong + / polarity. [. . . ] Connect the input and output cables of the units. Connect the power wire, power control wire and grounding wire following this order. Connect the negative - terminal of the battery. 2WARNING Accessories Part name Terminal cover (Power terminal) Self-tapping screws (ø4 × 16 mm) External View Number of Items 1 4 Installation Since the power amplifier has no parts which require operation, it can be installed at a position away from the driver's seat without any hindrances. As generally accepted positions for its installation, places such as inside the trunk, etc. can be considered. 2CAUTION To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery's positive terminal. 2CAUTION 28 A 50 A × 1 [25 A × 2] 5 mm2 (AWG 10) or greater × 1 · 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. · 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. 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. 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 FCC WARNING This equipment may generate or use radio frequency energy.

Connecting a speaker with an impedance lower than 4 ohms may damage the unit. · Be sure to connect capacitors to speakers to which high frequencies will be passed. Failure to do so will result in a drop of the combined impedance with the subwoofer. [. . . ]
