GETTING STARTED
•Turn off the audio system. It is also
advisable to disconnect the negative (–)
terminal of your vehicle’s battery whenever
performing installation work.
•Before cutting, drilling or inserting any screw,
check clearances on both sides of the planned
mounting surface. Also check for any potential
obstacles, such as window tracks and motors,
wiring harnesses, etc. Check both sides of the
vehicle, many vehicles are not symmetrical!
•Always wear protective eyewear.
SPEAKER PLACEMENT CONSIDERATIONS
In most cases, your speakers will be placed into
factory speaker locations. If you have some speaker
mounting flexibility, keep the following in mind:
Lower mounting locations, such as the lower front
corner of a door or a kick-panel provide the greatest
path length distances for the sound emitted by the
speakers. For this reason, they are generally more
desirable than higher mounting locations. Higher
mounting locations will usually result in extreme
near-side soundstage bias which compromises the
stereo listening experience.
• Two 2.8 mm female crimpable connectors

SPEAKER INSTALLATION
The speaker should be installed in one of the
following ways depending on location:
Factory Location: 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 large connector is for
the positive terminal and the small connector is for the
negative terminal of each C2-350x.
You may also choose to run new speaker wires...
Run speaker wire to the desired mounting
locations. 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 should then
be covered with a protective, flexible PVC sleeve and
then run through the door jamb. Make sure that the
wires will clear door hinges and other structures in
the door. If you are unsure about any part of this
process, please contact your JL Audio dealer for
installation help.
!! WA RNING Double check the clearance for both speakers
before proceeding. Many cars are different from
one side to the other!
Your new speakers have been designed to install,
without modifications, into most vehicles that accept
a 3.5-inch (90 mm) speaker. Most factory 3.5-inch
speakers use two mounting screws which will line up
with the mounting holes on your C2-350x speakers.
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 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.
Install as shown in Diagram A (page 5). Use the
supplied mounting clips unless the factory holes
already feature threaded inserts. Hand-tighten the
screws evenly to avoid bending the speaker frame!

WA R N I N G Double check the clearance for both speakers
before proceeding. Many cars are different from
one side to the other!
Select an even surface. Tightening a speaker onto
an uneven surface can damage it. Use the supplied
template to mark the desired mounting location.
Mark the center and the outline of the mounting
hole as well as the mounting screw positions. 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 four 1/8-inch (3
mm) holes for the speaker’s mounting screws at the
positions you have marked. Also drill a pilot hole
in the center of the speaker mounting hole at this
time. Then, using a saber saw, make the circular cut
out for the speaker. File any rough edges. Insert the
mounting clips with the flat side towards the speaker
as shown in Diagram A (page 5).
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 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.
Connect the speaker wires, observing correct
polarity, and install the speaker as shown in Diagram
A (page 5). Hand-tighten the screws evenly to avoid
bending the speaker frame!
Because 3.5-inch speakers are rarely used for
custom mounting, grilles are not supplied with the
C2-350x speakers. Should you need them, you will
need to purchase aftermarket grilles separately.
