Grilles are not included with C1 speakers, as they
are designed for installation into OEM (factory)
speaker locations, located behind factory grilles.
Should you need grilles, you will need to purchase
aftermarket grilles separately.

Prolonged exposure to sound pressure levels in
excess of 100dB can cause permanent hearing
loss. These high-performance loudspeakers can
exceed this level. Please exercise restraint in their
operation in order to preserve your ability to enjoy
their fidelity.

C1 speakers are designed for installation into
OEM speaker locations, mounted behind factory
panels/grilles. Depending on the equipment used
or design of your audio system, you may use the
factory speaker wires or run new speaker wires to
each speaker location. You will also need to run new
speaker wires if you elect to mount your speakers in
custom locations. Select the wiring method that is
appropriate for your audio system and equipment.
If you are unsure about this or any steps in the
installation process, please contact your JL Audio
dealer for installation help.
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 each C1-525x.
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.

Double check the clearance for both speakers
before proceeding. Many cars are different from
one side to the other!
Speaker Installation in Factory Locations:
Your new speakers have been designed to install,
without modifications, into most vehicles with
OEM speaker locations that accept a 5.25-inch (130
mm) speaker. Many factory 5.25-inch speakers use
four mounting screws, which will line up with the
mounting holes on your C1-525x speakers, as shown
in Diagram A (page 5). Some vehicles may require
adaptor rings to achieve correct clearances and
spacing. Consult your JL Audio dealer for details on
your particular vehicle
It is absolutely vital that the speaker frame fits into
the mounting hole cleanly. This must be checked prior
to tightening the screws. Never force the frame into
a hole that is too small, and do not attempt to tighten
the speaker onto an uneven surface. This will damage
your speakers.
The speaker should 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.
!! WA R N I N G
Hand-tighten the screws evenly in a criss-cross
pattern to avoid bending the speaker frame or
stripping the mounting screws.
