How Car Audio Works
FM reception
Ionosphere
AM and FM radio signals are broadcast
from transmitter towers located around
your city. They are intercepted by the
radio antenna on your car. This signal is
then received by the radio and sent to
your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear.
This can be due to factors such as the
distance from the radio station, closeness
of other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area.
AM reception

AM broadcasts can be received at greater
distances than FM broadcasts. This is
because AM radio waves are transmitted
at low frequencies. These long, low fre-
quency radio waves can follow the curva-
ture of the earth rather than travelling
straight out into the atmosphere. In addi-
tion, they curve around obstructions so
that they can provide better signal cover-
age.

FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM broad-
casts generally begin to fade at short

distances from the station. Also, FM sig-
nals are easily affected by buildings,
mountains, or other obstructions. These
can result in certain listening conditions
which might lead you to believe a prob-
lem exists with your radio. The following
conditions are normal and do not indicate
radio trouble:
