[. . . ] 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. [. . . ] They can scratch the surface of the panel and/or cause the indicator letters to peel off. When the unit is used in the ACC ON position without turning the engine ON, it depletes the battery. There is a Protection function installed in the unit to protect the unit and speakers from various problems. Part name Self-tapping screws (ø4 × 16 mm) Terminal cover (Power terminal) Speaker level input cable External Number of View Items 4 1 1 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. Set this control according to the pre-output level of the center unit connected with this unit, or to the maximum power output of the genuineaccessory car stereo. NOTE For the pre-output level or the maximum power output, refer to the <Specifications> in the instruction manual of the center unit. When you wish to use the unit as a stereo amplifier, stereo connections are used. the speakers to be connected should have an impedance of 2 or greater. When multiple speakers are to be connected, ensure that the combined impedance is 2 or greater for each channel. When you wish to use the unit as a highoutput monaural amplifier, bridged connections are used. When multiple speakers are to be connected, ensure that the combined impedance is 4 or greater. 2CAUTION The rated input of the speakers should be no less than the maximum output of the amplifier. 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. [. . . ] 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. Speaker level input cable Genuine-accessory car stereo (No line output center unit etc. [. . . ]
