TROUBLE
SHOOTING
THE
SYSTEM
Before
you
can
properly address the problem,
you
must
first
find the component that is
causing the problem.
This
will take patience
and
aprocess
of
elimination.
We
have put together this trouble-shooting
guide
if
you
experience problems
after
installing the amplifier.
Please
keep
in
mind
that the majority
of
problems incurred are
caused
by
improper installation
and
not the equipment itself.
In
addition, there are
many
components
in
the system that
could
cause
various signal problems
such
as
inducted
electrical noise
and
engine noise.
