For a smooth operation of your
SounDigital
amplifier, it is
important that the minimum working impedance is res-
pected.
Never connect the speakers with a lower
impedance than the amplifier nominal
impedance, otherwise it will be damaged.

Warning!
You should never connect or disconnect
RCA cables with the amplifier on,
because it may damage the head unit or
the amplifier.
Keep the RCA cables together, but away from the power or
the audio output cables and away from electric equipment
such as electronic fuel injection centrals, electric engines,
etc.
