English 7■ Installation procedureSince there are large variety of settings andconnections possible according to applications, readthe instruction manual well to select the propersetting and connection.1. Remove the ignition key and disconnect thenegative - terminal of the battery to prevent shortcircuits.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 andgrounding wire following this order.6. Install the unit in the car.7. Connect the negative - terminal of the battery.2 WARNINGTo prevent fire caused by a short in the wiring,connect a fusible link or breaker nearby the battery’spositive terminal.2 CAUTION• If sound is not output normally, immediately turnpower off and check connections.• Be sure to turn the power off before changing thesetting of any switch.• If the fuse blows, check wires for shorts, then replacethe fuse with one of the same rating.• Check that no unconnected wires or connectors aretouching the car body. Do not remove caps fromunconnected wires or connectors to prevent shortcircuits.• Connect the speaker wires to appropriate speakerconnectors separately. Sharing the negative wire ofthe speaker or grounding speaker wires to the metalbody of the car can cause this unit to fail.• After installation, check that the brake lamps,winkers, and wipers work properly.■ Wiring• Take the battery wire for this unit directly from thebattery. If it's connected to the vehicle’s wiringharness, it can cause blown fuses etc.• If a buzzing noise is heard from the speakers whenthe 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 ofthe iron plate by using Grommets.• Connect the ground wire to a metal part of the carchassis that acts as an electrical ground passingelectricity to the battery‘s negative - terminal.Do not turn the power on if the ground wire is notconnected.• Be sure to install a protective fuse in the powercord near the battery. The protective fuse shouldbe the same capacity as the unit’s fuse capacity orsomewhat larger.• For the power cord and ground, use a vehicle type(fireproof ) power wring cord with a current capacitygreater than the unit’s fuse capacity. (Use a powerwiring cord with a diameter of 5 mm² (AWG 10) orgreater.)• When more than one power amplifier are goingto be used, use a power supply wiring wire andprotective fuse of greater current-handling capacitythan the total maximum current drawn by eachamplifier.■ Speaker selection• The rated input power of the speakers that aregoing to be connected should be greater than themaximum output power (in Watts) of the amplifier.Use of speakers having input power ratings thatare less than the output power of the amplifier willcause smoke to be emitted as well as damage.• The impedance of the speakers that are goingto be connected should be 2Ω or greater (forstereo connections), or 4Ω or greater (for bridgedconnections). When more than one set of speakersare going to be used, calculate the combinedimpedance of the speakers and then connectsuitable speakers to the amplifier.2 Ω8 Ω4Ω4Ω 4Ω4ΩCombined impedance
