( Before you start ) Before connecting/ installing the amplifier • A wARNING • • • • • • • • The use of a special red battery and ground wire RD-223, available separately, is recommended. Connect the battery wire directly to the car battery positive terminal ®and the ground wire to the car body. This unit is for vehicles with a 12 V battery and negative grounding. Before installing in recreational vehicles , trucks or buses, check the battery voltage.
(Before you start • ) (Setting the unit The amplifier will reduce the power output if the temperature inside the amplifier gets high. If the temperature gets too high, the power indicator will turn off, and the amplifier will shut down. ) What's what GM-A6704 Front side MPFFREQ LPF IHPF liA.

Select LPF. This eliminates high range frequency and outputs low range frequency. • When the full range speaker is connected: Select HPF or OFF. HPF eliminates low range frequency and output high range frequency. OFF outputs the entire frequency range.

(Connecting the units -) About suitable specification of speaker Connecting the speakers The speaker output rnode can be four-channel. three-channel (stereo and mono) or two-channel (stereo or mono). Connect the speaker leads based on the mode and the figures shown below. Ensure speakers conform to the following standards. otherwise there is a risk of fire, smoke or darllage. Speaker impedance is 2 n to 8 n. or 4 n to 8 n for two-channel and other bridge connections.
