User manual KENWOOD CAW-CP7150

[. . . ] When the protection function is triggered, the Power indicator goes off and the amplifier stops operating. â· When a speaker wire may be short-circuited. When the unit malfunctions and a DC signal is sent to the speaker output. â· When the internal temperature is high and unit won't operate. [. . . ] Otherwise heat build-up occurs and the unit may be damaged. â· Install this unit in a location which allows heat to easily dissipate. Once installed, do not place any object on top of the unit. â· 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. Do not mount the unit in a place where the cooling fan and ducts of the unit are blocked. 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. â· Do not install near the dashboard, rear tray, or air bag safety parts. â· 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. â· After installing the unit, check to make sure that electrical equipment such as the brake lamps, turn signal lamps and windshield wipers operate normally. â· Be sure to turn the power off before changing the setting of any switch. â· If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating. 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. â· After installation, check that the brake lamps, winkers, and wipers work properly. 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. â· 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. Genuine-accessory car stereo (No line output center unit etc. ) Speaker level input cable Car fuse box 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.
