KAC-8106D CLASS D MONO POWER AMPLIFIER INSTRUCTION MANUAL 高性能D © 2012 JVCKENWOOD Corporation B64-5053-00/00 (WV) Safety precautions WARNING To prevent injury or fire, take the following precautions: • Mounting and wiring this product requires skills and experience. For safety's sake, leave the mounting and wiring work to professionals. • When extending the ignition, battery, or ground wires, make sure to use automotive-grade wires or other wires with the range of 5 mm² (AWG 10) 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. 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 open the top or bottom covers of the unit. • Do not install the unit in a spot exposed to direct sunlight or excessive heat or humidity. Also avoid places with too much dust or the possibility of water splashing. • When replacing a fuse, only use a new one with the prescribed rating. Using a fuse with the wrong rating may cause your unit to malfunction. • To prevent a short circuit when replacing a fuse, first disconnect the wiring harness. NOTE • If you experience problems during installation, consult your Kenwood dealer. • If the unit does not seem to be working right, consult your Kenwood dealer. Cleaning the unit If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. CAUTION Do not wipe the panel with a hard cloth or a cloth 4Ω dampened by volatile solvents such as paint thinner and alcohol. They can scratch the surface of the pa4nΩel and/or cause the indicator letters to peel off. Protection function The protection function is activated in the following situations: This unit is equipped with a protection function for protecting this unit and your speakers from various accidents or problems that can occur. When the protection function is triggered, the power indicator goes off and the amplifier stops operating. • When a speaker wire may be short-circuited. • When a speaker output contacts ground. • When the unit malfunctions and a DC signal is sent to the speaker output. • When the internal temperature is high and unit won't operate. 7 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. • Connect the ground wire to a metal part of the car chassis that acts as an electrical ground passing electricity to the battery's negative · terminal. Do not turn the power on if the ground wire is not connected. • Be sure to install a protective fuse in the power cord near the battery. 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. (Use a power wiring cord with the range of 5 mm² (AWG 10) or more.) • 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. 7 Speaker selection • 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. • Use speakers that have an impedance of 2Ω or greater. When more than one set of speakers are going to be used, calculate the4Ωcombined impedance4oΩf the 4Ω speakers and then connect suitable speakers to the amplifier. 4Ω 8Ω 2Ω To prevent battery rise 4Ω 4Ω When the unit is used in the ACC ON position without4Ω 4Ω turning the engine ON, it depletes the battery.

Remove the ignition key and disconnect the negative · terminal of the battery to prevent short circuits. 2. Set the unit according to the intended usage. 3. Remove the Dressing cover. 4. Connect the input and output wires of the units. 5. Connect the speaker wires. 6. Connect the power wire, power control wire and grounding wire following this order. 7. Install the installation fittings in the unit. 8. Attach the unit. 9. Attach the Dressing cover. 10. Connect the negative · terminal of the battery. CAUTION • Do not install in the below locations; (Unstable location, In a location that interferes with driving, In a location that gets wet, In a dusty location, In a place that gets hot, In a place that gets direct sunlight, In a location that gets hit by hot air) • Do not install the unit under the carpet. Otherwise heat build-up occurs and the unit may be damaged. • Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit. • The surface temperature of the amplifier will become hot during use. Install the amplifier in a place where people, resins, and other substances that are sensitive to heat will not come into contact with it. • When making a hole under a seat, inside the trunk, or somewhere else in the vehicle, check that there is nothing hazardous on the opposite side such as a gasoline tank, brake pipe, or wiring harness, and be careful not to cause scratches or other damage. • Do not install near the dashboard, rear tray, or air bag safety parts. • The installation to the vehicle should securely fasten the unit to a place in which it will not obstruct driving. If the unit comes off due to a shock and hits a person or safety part, it may cause injury or an accident. • After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally. 7 1 路。 2 3 4 5 6 顺序。 7 8 9 10 注意 警告 5mm2(AWG 10 注意 使用。 12V 4Ω 4Ω 行更换。 7 接线 5mm2(AWG 10 7 4 2 欧姆。4 4Ω组 扬声器。 4Ω <例> 8Ω 2Ω 4Ω 4Ω 注 4Ω 4Ω 4。Ω 4Ω 4Ω 8Ω 4Ω 4Ω 2Ω 综合阻抗 注意 当本机在ACC ON 保护功能 本机装4Ω有保护4 当保护4Ω功能被4 作。 4Ω • DC 4Ω 4Ω 4Ω 4Ω 4Ω Connection / 连接 WARNING Particular attention must be given to making good electrical contact at the amplifier-output and speaker terminals. Poor or loose connections can cause sparking or burning at the terminals because of the very high power that the amplifier can deliver. 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. • After installation, check that the brake lamps, turn signal lamps and windshield wipers work properly. WARNING 警告 Remove the ignition key and disconnect the negative · terminal of the battery to prevent short circuits. 7 Power wire and speaker wire connection 7 Center unit (CD receiver, etc CD Power control wire Protective fuse Battery wire WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery's positive terminal.
