TESTING THE
CONNECTIONS
Follow these steps to check your au-
tosound system before adjusting and
mounting the crossover.
1. Turn on your autosound system
and adjust the volume to a com-
fortable level. The POWER indi-
cator lights.
2. Play a cassette tape or CD that
has a wide dynamic range, or
tune to a strong FM station.
3. If the sound from any speaker is
distorted or has static (or if there
is no sound from a speaker), turn
off the power immediately, then
check the wiring connections.
If the system sounds with no dis-
tortion or static, proceed to “Ad-
justing the Controls.”
