C7-100ct: Installation
PROTECTION CAPACITOR
A high-quality 15μF protection capacitor is
included with the C7-100ct to guard against damage
from transient electrical pops (turn-on/off). This
capacitor is not a substitute for high-pass filtering
and must be connected in all installations. The
capacitors value has been selected so as not to
interfere with a properly set active high-pass filter.
The protection capacitor supplied with your
C7-100ct should be installed in a dry location and
as near as possible to the tweeter. Connect the
protection capacitor in-line (series) with the tweeter’s
positive (+) lead, as shown in Diagram A below. The
capacitor is bipolar and may be connected in either
direction. Make sure to insulate the capacitor’s leads
to guard from touching against any exposed metal.
Use plastic cable ties or a similar fastener to securely
mount the capacitor 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 tweeter mounting
locations to the amplifier outputs. Then connect the
harness wire leads to the speaker/amplifier outputs
and tweeters, observing correct polarity. See
Diagram A below for details.
WARNING
!!
It is absolutely vital that the protection capacitor
is connected, as shown in Diagram A. Failure to
connect the protection capicitor as shown will result
in damage which is NOT covered under warranty.
TWEETER INSTALLATION
C7 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 (two for the wires and one for the mounting
screw). 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 1.88-inch (48 mm)
diameter hole to be cut in the vehicle panel. At least
1.75-inch (44 mm) of clearance is required behind
the tweeter mounting surface for the spring clip and
1-inch machine screw used to mount the fixture.
In limited depth applications, it may be necessary
to cut down the length of the machine screw, or to
use a shorter screw (not supplied). Hand-tighten the
machine screw until the fixture is secure, as shown
in Diagram C.
