TWEETER INSTALLATION
C1 tweeters have been designed for surface
or flush-mounting. Before choosing a method,
carefully inspect the desired mounting location
to determine which method will work best.
Surface-Mount : uses the supplied surface-
mount fixture and requires the drilling of three
holes (one for the wires and two for the mounting
screws). This application is useful when mounting
the tweeters to a panel that has insufficient clearance
behind it for the tweeter’s magnet structure.
Flush-Mount : yields a custom-installed
appearance and requires a 1-1/2-inch (38
mm) diameter hole to be cut in the vehicle
panel, with at least 0.40-inch (10 mm) of
clearance behind the mounting surface for
the tweeter and up to 1.45-inch (37 mm) for
the stud bolts used to mount each tweeter.
TWEETER PROTECTION
The C1 crossover networks are equipped with
an advanced electronic tweeter protection circuit
designed to minimize the possibility of tweeter
failure. This electronic device monitors current going
to the tweeter and will disconnect the tweeter from
the signal when it senses overload. Should this occur
while listening to the audio system, simply reduce the
volume for a few seconds and the protection circuit
will reset itself automatically.
CROSSOVER NETWORK INSTALLATION
The crossover networks supplied with your C1
System should be installed in a dry location inside
your vehicle. DO NOT INSTALL THEM INSIDE
OF A DOOR! Doors often get wet on the inside,
which can damage your crossover networks and
could potentially damage your entire sound system.
Use plastic cable ties or a similar fastener to securely
mount each crossover to avoid coming loose in the
event of a collision, sudden jolt or repeated vibrations
during normal use. Make sure that your mounting
location will not cause damage to wiring or any other
vital component of your vehicle.
TWEETER CONNECTIONS
Run the wire leads from the crossovers to
the tweeter mounting locations and to the speaker/
amplifier outputs. Then connect the harness wire
leads to the speaker/amplifier outputs and tweeters,
observing correct polarity. See Diagram C below
for details.
WA R N I N G
!!
It is absolutely vital that your component
tweeter is connected, as shown in Diagram C.
Failure to connect the tweeter as shown will
result in damage which is NOT covered under
warranty. Only use in-line filters clearly marked
“C1-075cthp”.
