INSTALLATION
You can easily connect this cross-
over. However, improper connec-
tions can damage your crossover and
other components in your autosound
system, and possibly your vehicle’s
electrical system. Before you begin,
you should know:
Which wire is the power wire in
your vehicle’s electrical system
If your autosound system has
line-level or speaker-level outputs
Before you install your crossover,
carefully read all the installation in-
structions in this owner’s manual.
Notes:
Use audio patch cables with
phono-type connectors (avail-
able at your local RadioShack
store) to complete the low level
input/output connections.
Use your autosound system’s
speaker wires to complete the
high level input connections.
Use 18-gauge wire (available at
your local RadioShack store) to
complete the power connections.
Turn your autosound system’s
volume all the way down before
installation.
Set the subwoofer amplifier gain
(input level) and crossover input
level controls to their midpoints.
CHOOSING A
MOUNTING LOCATION
Choose the mounting location for the
crossover first, but do not mount it un-
til you have connected the wiring, ad-
justed the controls, and confirmed
that the crossover operates properly
with your system. By choosing the lo-
cation first, you can later mount the
crossover without re-routing the
wires.
Choose a mounting location that:
Is as near as possible to your
autosound system connections (It
is important to keep the audio
cables as short as possible to
reduce noise and interference)
Does not interfere with the opera-
tion of the vehicle
Is not directly in front of a heating
vent
Allows drilling of mounting holes
without damaging other vehicle
components
Allows convenient and safe rout-
ing of wires
