4.-

Speaker connection terminals. The output impedance is from 4 to 8 Ω. Connect the brown cable to the
terminal marked with + (speaker) and the white cable to the terminal marked with – (speaker).

CONNECTION

Connect the cables supplied in the screw terminals on the back panel of the amplifier. 

SPEAKER CONNECTION

Connect the output terminals to the speaker/speakers, the brown cable (+) to the positive terminal and the
white (-) to the negative terminal.
Make sure the connections are made correctly and that they are well insulated to avoid short circuits in the
speaker output which could damage the amplifier.
The speaker output accepts the connection of a charge impedance from 4 to 8 Ω. The speaker output
impedance is automatically adjusted to the charge, but the best results are achieved if the amplifier is charged
with 4 Ω.
If various speakers are connected, the total impedance must be between 4 and 8 Ω. If the amplifier is charged
with higher or lower impedance, the amplifier could be damaged. 

EXAMPLE OF A PARALLEL CONNECTION

POWER SUPPLY CONNECTION

Connect the black cable (-) to the negative on the battery and the red cable (+12 V DC) to the positive on the
battery. 

Respect the polarity of the batteries.

The amplifier must only be installed in cars with 12 V batteries with the negative ground through the chassis.

When the fuse is replaced, use one with the same value.
