• 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 mm. (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 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. • 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. 4. 4. 4. 4. 2. 8.

Speaker level input terminals • The genuine-accessory car stereo shall have a maximum power output of no more than 40 W. • Connect the power control lead to a power supply which can be turned ON/OFF by the ignition key switch (ACC line). With this connection, pop noise may be generated when the power of the genuine-accessory car stereo is switched ON/OFF. Speaker output terminals (A.ch/ B.ch) • Stereo Connections: 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. • Bridged Connections: Make connections to the LEFT channel 9 and the RIGHT channel · SPEAKER OUTPUT terminals. The speakers to be connected should have an impedance of 4. or greater. When multiple speakers are to be connected, ensure that the combined impedance is 4. or greater.

Before calling service, first check the following table for possible problems. PROBLEM POSSIBLE CAUSE SOLUTION 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.) • 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 9 / · polarity. • A speaker wire is pinched by a screw in the car body. • The switches may be set improperly. • Connect the input (or output) cables. • Check connections by referring to
