4. Connect the speaker wires. 5. Connect the power wire, power control wire and grounding wire following this order. 6. Install the unit in the car. 7. Connect the negative - terminal of the battery. 2WARNING To prevent fire caused by a short in the wiring, connect a fusible link or breaker nearby the battery’s positive terminal. 2CAUTION • If sound is not output normally, immediately turn power off and check connections. • Be sure to turn the power off before changing the setting of any switch. • If the fuse blows, check wires for shorts, then replace the fuse with one of the same rating. • Check that no unconnected wires or connectors are touching the car body. Do not remove caps from unconnected wires or connectors to prevent short circuits. • Connect the speaker wires to appropriate speaker connectors separately. 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. ¦ 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 5 mm2 (AWG 10) 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 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. • 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 .

Before calling service, first check the following table for possible problems. PROBLEM No sound. (No sound from one side.) (Blown fuse.) The output level is too small (or too large). The sound quality is bad. (The sound is distorted.) POSSIBLE CAUSE • Input (or output) cables are disconnected. • Protection circuit may be activated. • Volume is too high. • The speaker cord is shorted. The input sensitivity adjusting control is not set to the correct position. • The speakers wire are connected with wrong + / -polarity. • A speaker wire is pinched by a screw in the car body. • The switches may be set improperly. SOLUTION • Connect the input (or output) cables. • Check connections by referring to
