(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. • Mounting and wiring this product requires skills and experience. For safety’s sake, leave the mounting and wiring work to professionals. 2CAUTION 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 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. 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 with a current capacity greater than the unit’s fuse capacity. (Use a power wiring cord with a diameter of 8 mm. (AWG 8) 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 • 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. • Use speakers that have an impedance of 1. or greater. 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. 2. 8. Combined impedance 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. 2CAUTION 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. Use it after starting the engine. 2 English English 3 Installation Accessories Part name External View Number of Items Self-tapping screws (o4 . 16 mm) 4 Terminal cover (Power terminal) 1 Speaker level input cable 1 Hexagon wrench 1 Installation procedure Since there are large variety of settings and connections possible according to applications, read the instruction manual well to select the proper setting and connection. 1. 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. Connect the input and output wires of the units. 4. Connect the speaker wires. 5. Connect the power wire, power control wire and grounding wire following this order. 6. Install the installation fittings in the unit. 7. Attach the unit. 8. Connect the negative - terminal of the battery. 2CAUTION • 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 ...
