[. . . ] ⷠ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. [. . . ] Take the battery wire for this unit directly from the battery.

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. 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 the range of 14 mm² (AWG 6) to 21 mm² (AWG 4). ⷠ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. If the front panel gets dirty, turn off the power and wipe the panel with a dry silicon cloth or soft cloth. ⷠ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.

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. You can use wires with the following thicknesses: Battery wire and ground wire AWG 4 ­ AWG 6 Speaker wire AWG 8 ­ AWG 12 Make a cut in the wire sheath (insulator made from vinyl, etc. [. . . ] Setting this control cuts the frequencies below the respective frequency. This improves the reproduction performance of the speakers by eliminating unnecessary oscillations which will not become sound. When the power is turned on, the Power indicator lights. Lights this indicator when the protection function is activated. [. . . ]
