How Vehicle Audio Works

FM reception
AM and FM radio signals are broad-
cast from transmitter towers located
around your city. They are intercept-
ed by the radio antenna on your vehi-
cle. This signal is then processed by
the radio and sent to your vehicle
speakers.
When a strong radio signal has
reached your vehicle, the precise
engineering of your audio system
ensures the best possible quality
reproduction. However, in some
cases the signal coming to your vehi-
cle 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 sta-
tions or the presence of buildings,
bridges or other large obstructions in
the area.

AM reception
AM broadcasts can be received at
greater distances than FM broad-
casts. This is because AM radio
waves are transmitted at low fre-
quencies. These long distance, low
frequency radio waves can follow the
curvature of the earth rather than
travelling straight. In addition, they
curve around obstructions resulting
in better signal coverage.
