6.7. Connecting a loudspeaker

Use a loudspeaker with an impedance of at least 4 Ohm. When
connecting a loudspeaker with a lower impedance, the output for the
loudspeaker will be damaged. As a rule the playback quality increases
with the loudspeaker´s size. For that reason you should choose a
loudspeaker as large as possible.
In addition, the correct mounting of the loudspeaker is decisive for the
sound reproduction. The loudspeaker membrane should emit directly to
the outside, the other side into the inside of the vehicle which should
be as airtight as possible. The larger the volume in the inside, the
better is the reproduction quality. Suitable for the mounting are e.g. the
bottom of the vehicle or the back of the driver´s cab.
