C7-350cm:
Installation
SPEAKER WIRING
If you will be using the factory speaker wires, it
may be necessary to change the terminations. This
may be accomplished by using an adaptor plug
or simply by cutting the factory connector off and
using the supplied crimp connectors to terminate
the speaker wires. The larger connector is for the
positive terminal and the smaller connector is for the
negative terminal of the C7-350cm.
If you choose to run new speaker wires, protect
all wiring from sharp edges by carefully routing
them, securing them and using grommets and loom
where appropriate. If you are running wires into a
door, use existing factory wiring boots whenever
possible. If you are drilling new holes, file their edges
and install rubber grommets into each hole. Wires
running into car doors should be covered with a
protective, flexible PVC sleeve. Make sure that the
wires will clear door hinges and other structures in
the door.
SPEAKER INSTALLATION
The speakers should be installed in one of the
following ways depending on location:
Factory Location: Your new speakers have been
designed to install, without modifications, into most
vehicles that accept a 3.50-inch (90 mm) speaker.
Most factory 3.50-inch speakers use four mounting
screws which will line up with the mounting holes
on your woofers.
It is absolutely vital that the speaker frame fits into
the mounting hole cleanly. This must be checked
prior to tightening the screws. Do not force the
frame into a hole that is too small. Do not tighten the
speaker onto an uneven mounting surface. This will
damage your speakers. The speaker should also fit so
that air does not leak around the mounting flange.
Air leaks will cause a severe degradation in sound
quality. Seal any air leaks with an automotive-grade
sealant material. Hand-tighten the screws evenly in
a criss-cross pattern to avoid bending the speaker
frame or stripping the mounting screw holes. (See
Diagram C).
CROSSOVER CONSIDERATIONS
Passive crossover networks are not included with
C7 drivers, as they are designed for active systems.
Actively configured systems allow all filtering and/or
equalization to be configured prior to reaching the
amplifier, thus avoiding the technical compromises
of passive crossover networks. The result is
linear, crystal clear audio output and minimal
distortion.
For optimum performance, we strongly
recommend the use of a high-quality DSP and a
dedicated amplifier channel.
Custom Location: Select a desired mounting
location with an even surface. Tightening a
speaker onto an uneven mounting surface can
damage it. Mark the center and the outline of the
speaker’s mounting hole. Before drilling or cutting
on your interior panels, use a utility knife to cut
any fabric, vinyl or leather from hole locations.
These materials can easily be snagged by a drill or
a saw, causing damage to the panel and possible
bodily injury. Drill a pilot hole in the center of the
proposed speaker mounting hole. Then, using
an appropriate cutting tool, make the circular
cut out for the speaker. File any rough edges.
After cutting the hole, check to see that
the speaker frame fits into its mounting
hole cleanly. Do not force the frame into a hole
that is too small. Once the speaker is in place, use
the holes on the speaker’s mounting flange to
mark the panel where the four mounting screws
will be positioned (See Diagram D). Remove the
speaker and drill 7/64-inch (2.78mm) holes at each
mark. Connect the speaker wires, observing correct
polarity, and secure the speaker and grille tray to the
panel by evenly tightening by hand the provided #6
x 1.25 inch (32 mm) mounting screws. Make sure the
speaker is secured so that air does not leak around
the mounting flange. Air leaks will cause a severe
degradation in sound quality. Seal any air leaks with
an automotive-grade sealant material.
Finally, select your preferred grille style and
insert it into the grille tray, pressing around
its edge until seated firmly in the tray.
