User manual KENWOOD KAC-M526

[. . . ] The protective fuse should be the same capacity as the unit’s fuse capacity or somewhat larger. • For the power cord and ground, use a vehicle type (fireproof ) power wring cord with a current capacity greater than the unit’s fuse capacity. (Use a power wiring cord with a diameter of 5 mm2 (AWG 10) or greater. ) • When more than one power amplifier are going to be used, use a power supply wiring wire and protective fuse of greater current-handling capacity than the total maximum current drawn by each amplifier. Speaker selection CAUTION To prevent damage to the machine, take the following precautions: • Be sure the unit is connected to a 12V DC power supply with a negative ground connection. • Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. [. . . ] • When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the4Ω wrong rating may cause your unit to malfunction. 4Ω • To prevent a short circuit when replacing a fuse, first disconnect the wiring harness. • The input power of the speakers that are going to be connected should be greater than the 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. 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. 4Ω 4Ω 4Ω 8Ω 2Ω 4Ω Combined impedance 4Ω 4Ω 4Ω 4Ω NOTE 4Ω 4Ω 4Ω 4Ω • If you experience problems during installation, consult your Kenwood dealer. 4Ω • If the unit does not seem to be working right, consult your Kenwood dealer. Cleaning the unit 4Ω 4Ω 4Ω If the front panel gets dirty, turn off 2Ω power and the 8Ω wipe the panel with a dry silicon cloth or soft cloth. CAUTION Wiring • Take the battery wire for this unit directly from the battery. If it’s connected to the vehicle’s wiring harness, it can cause blown fuses etc. • If a buzzing noise is heard from the speakers when the engine is running, connect a line noise filter (optional) to each of the battery wire. • Do not allow the wire to directly contact the edge of the iron plate by using Grommets. Do not wipe the panel with a hard cloth or a cloth dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the panel and/or cause the indicator letters to peel off. To prevent battery from running out  When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. • When a ground wire of the center unit (cassette receiver, CD receiver, etc. ) or this unit is not connected to a metal part serving as an electrical ground passing electricity to the battery's negative · terminal. English KAC-M526_M_1English. indd 4 08. 10. 15 5:05:51 PM Connection WARNING Remove the ignition key and disconnect the negative · terminal of the battery to prevent short circuits. CAUTION • If sound is not output normally, immediately turn power off and check connections. • 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 wires or connectors are touching the car body. Do not remove caps from unconnected wires 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. NOTE • 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. Speaker level input connections Speaker output terminals • The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. • As this unit accepts speakers with a minimum impedance of 2 ohms, connect speakers with 2-ohms or higher impedance to these terminals.
