Section 03 Connecting the units ! Never band together multiple speaker's negative cables. ! If the system remote control wire of the amplifier is connected to the power terminal via the ignition switch (12 V DC), the amplifier will remain on with the ignition whether the car stereo is on or off, which may exhaust battery if the engine is at rest or idling. ! Install and route the separately sold battery wire as far as possible from the speaker wires. Install and route the separately sold battery wire, ground wire, speaker wires and the amplifier as far away as possible from the antenna, antenna cable and tuner. Connecting the speakers This amplifier can be connected to two speakers in parallel. Connect the speaker leads to suit the mode according to the figure shown below. Precautions for parallel connection ! When wiring two speakers in parallel, make sure that the synthetic impedance is from 1 W to 8 W to prevent the amplifier from catching fire, generating smoke and/or being damaged. ! When connected in parallel with the synthetic impedance less than 1 W, as a normal function, this amplifier may automatically be set on mute if outputting high volume sound. Turn down the volume until the mute function is canceled. When connecting to one speaker Speaker output When connecting to two speakers The output from two speakers is the same as that of one speaker. Speaker output 8 En
