IMPORTANT
Before you start your installation, please read the following instructions to achieve maximum product performance. Although this installation guide explains
how to install the Reference 6513cs in a general sense,
it does not show the exact installation methods for
your particular vehicle. Installation of automotive
stereo components requires extensive experience in
dealing with a variety of mechanical and electrical
procedures. If you do not feel you have the experience,
do not attempt the installation yourself, but instead
ask your Authorized Infinity Car Audio Dealer about
professional installation options.
PRECAUTIONS AND NOTES
• Turn off all audio system and other electrical devices
before you start. As an extra precaution, disconnect the
(–) negative lead from your vehicle’s battery.
• Protect the speaker components by keeping them in
their packages until final installation. This will keep
the magnets in these components from attracting
metal clips and filings.
• When moving a speaker component, always rest each
component so that the cone or dome is facing up.
• Never use force to install any speaker component.
• At the installation sites, locate and make a note of all
fuel lines, hydraulic brake lines, and electrical wiring.
Use extreme caution when cutting or drilling in and
around these areas.
• Check clearances on both sides of a planned mounting
surface before drilling any holes or installing any
screws. Remember that the enclosed screws can extend
up to an inch behind the surface.
• Before drilling or cutting holes, use a utility knife to
remove unwanted fabric or vinyl. This will help keep
the material from snagging in a drill bit or hole saw.
• For faithful music reproduction, use only high-quality
components with this speaker system.
• A common cause of speaker failure is trying to get
more out of your amplifier than it is able to deliver.
We suggest using a high-quality amplifier with power
rating of at least 100 watts-per-channel into 4 ohms.
• All wires must be secure and protected against damage from folding seats, door jambs, etc. Use rubber
grommets when passing wires through holes in metal,
and allow “service loops” where needed. NEVER run
cables outside the vehicle, since exposure to the elements will corrode their insulation.
• Do not use the chassis of your vehicle as a speaker
ground connection.
• Do not operate the vehicle until you are certain that
all amplifiers, woofers, etc. are secure in the event of a
sudden stop or jolt.
• Only use the enclosed passive crossover network.
Modifying or bypassing the network may cause damage to your components and is not covered under the
terms of your warranty.
• Always wear protective eyewear when using power or
conventional tools.

SYSTEM APPLICATIONS(CONTINUED
)
APPLICATION NOTES – SINGLE AMPLIFIER SYSTEM (SEE FIGURE 1)
For a system with a single amplifier, we recommend using
a 50- to 150-watt amplifier. Leave the crossover jumpers
in place and observe the following:
• Connect left/right outputs from the amplifier to the corresponding left/right WOOFER inputs on the crossover.
• Connect the 165 mm (61⁄2") woofers, 102 mm (4")
midrange drivers, and 19 mm (3⁄4") soft-dome tweeters
to the crossover using the enclosed keyed, color-coded
hook-up wires, as shown in Figure 1.
• For woofers and midrange drivers, use the corresponding HI connections on the crossover.
• For tweeters, use the (tweeter) MID connections on the
crossover.
APPLICATION NOTES – BI-AMPLIFIED SYSTEM (SEE FIGURE 2)
For this application, we recommend two 50- to 150-watt
amplifiers to drive the woofers and satellite speakers (i.e.,
midrange drivers, and tweeters). On the crossover, connect pigtail jumpers only between MIDRANGE and
TWEETER inputs and hook-up the amplifiers, as shown
in Figure 2. The speaker connections are the same as
those listed for a single amplifier system.
NOTE: You may need additional hook-up wire and terminals
to connect the satellite amplifier to the crossover.
APPLICATION NOTES – TRI-AMPLIFIED SYSTEM (SEE FIGURE 3)
In a tri-amplified system, we recommend a 50- to 100-watt
amplifier for woofers and two 25- to 50-watt amplifiers to
drive the each pair of satellite speakers (i.e., midrange drivers, and tweeters). On the crossover, remove the entire pigtail jumper and connect the amplifiers, as shown in Figure 3.
The speaker connections are the same as those listed for a
single amplifier system.
NOTE: You may need additional hook-up wire and terminals
to connect the two satellite amplifiers to the crossover.
SPEAKER PLACEMENT
Where you place your speakers will greatly affect the total
sound quality of your vehicle’s audio system. Often the
best locations are compromises between the ideal sound
stage and the physical limitations of your vehicle. Here
are several techniques you can use to place a component
in a location where it sounds best:
• Use the supplied templates to find potential placement sites.
• Place each speaker component in its prospective
mounting position and make the system connections.
• Power on the system and listen to a variety of your
favorite music. Experiment with the midrange and
tweeter locations until you find the placement which
sounds the best. If possible, try placing these components on the same mounting plane. This will help minimize timing errors in emitting sound waves that occur
when they are spaced too far apart.
WOOFERS
The woofers will provide their best response when mounted in the rear deck of most vehicles, with the trunk acting
as the woofer enclosure. If this is not feasible, locate the
woofers so that there is at least 28 to 57 liters (1 to 2 cubic
feet) of airspace behind each one. The front door panels
are another possibility.
MIDRANGE DRIVERS
Choose a location for the midrange drivers that offers an
unobstructed path to the listener’s ears and also places
the midranges fairly near the tweeters (preferably on the
same mounting plane).
TWEETERS
Because of their small size, the tweeters can be mounted
in a number of convenient locations. Suggested areas
include the dash, door panels, rear deck, or rear window
pillars. For best imaging, install the tweeters at ear level,
aimed so that imaginary lines from the center of each
tweeter cross at a point between the two front passenger
seats. Make sure there are no obstructions between the
tweeters and listeners.

CROSSOVER INSTALLATION
6513CSA
UTOMOTIVECOMPONENTSPEAKERSYSTEM
The enclosed stereo crossover can be mounted in any convenient location. However, do not mount a crossover in an
exposed outside area, and try to place it closer to the
speakers than an amplifier.
NOTE: Use only the enclosed Infinity crossover. It is specifically designed to work with the Reference 6513cs speakers.
Use of any other crossover may damage one or more audio
components and is not covered by the warranty.
1. At the chosen site, use the crossover as a template to
mark the screw holes. Make sure the intended site provides necessary clearance for the mounting screws.
2. Use a hole punch for drilling guides. If necessary, clear
away any carpet or other material prior to drilling.
3. Use a drill with a 3.2 mm (1⁄8") bit to drill four holes.
4. Fasten the crossover to the surface with its supplied
5. Depending on your system configuration (refer to
WOOFER/MIDRANGE INSTALLATION
OOFER AND MIDRANGE DRIVER INSTALLATION NOTES

For most applications, the woofers and midrange drivers
will not need new openings, since they are specifically
designed to drop into existing cutouts in most cars, trucks,
and vans. However, if you decide to install a woofer or
midrange driver in a non-standard location, use the appropriate supplied template to trace a mounting site. Also
observe the following mounting precautions:
• Check the sites for adequate clearance and potential
water leakage. Make sure components will not interfere
with the operation of door controls or windows. Avoid
contact with door frames, handles, and window tracks.
• Pick a location with a strong, rigid structure to support
the weight of the component. You may have to build out
the mounting area if sufficient metal does not exist.
INSTALLING WOOFERS/MIDRANGE DRIVERS
To install the Reference 6513cs woofers and midrange drivers, refer to Figures 4 and 5 (on the next page) as you perform the following steps:
3. Use a drill with a 3.2 mm (1⁄8") to drill a pilot hole at

TWEETER INSTALLATION
Reference 6513cs tweeters are easy to install. Each is
housed in a surface-mount enclosure with grille and is
equipped with an attached color- and terminal-keyed wire
pigtail. For custom installations, each tweeter includes a
flush-mount kit that features an adjustable firing angle.
SURFACE-MOUNT INSTALLATION
Refer to Figure 6 (above) for correct orientation of the surface-mounting plate. A 7.9 mm (5⁄16 ") diameter hole is
required to pass tweeter wires and pre-attached terminals. Make sure each proposed hole will not extend beyond
the boundary of the tweeter enclosure.

make sure there is minimum mounting depth of 44.5 mm
(13⁄4") behind each panel.
1. At each chosen site, remove the panel and use the
flush-mount cup (or flush-mounting template) as a
guide to cut a hole for tweeter mounting.
2. Route the tweeter’s pigtail wire through each base and
carefully press each tweeter in until it snaps into place.
3. Insert each tweeter (and base) into a flush-mount cup
and route the tweeter’s (pigtail) wires through the
opening in the cup.
4. Place each entire assembly into a panel opening so the
cup lip is flush against the panel.
5. Route each set of tweeter wires through the cup’s nut
and hand-tighten each nut against back of the panel.
Figure 7. After the Reference 6513cs tweeter
is in its cup, hand-tighten the nut to flushmount the assembly on the panel.
6. Check each tweeter’s placement with the listening
position (e.g., on-axis placement provides the best performance). If necessary, loosen the nut, rotate the
assembly and adjust the tweeter’s angle, and retighten
the nut.
7. Connect tweeter wires to the appropriate connection
points and re-install each panel.
ADJUSTING THE SOUND
Initially connect the + leads (on the satellite crossover
connections) to the following terminals: woofer to HI,
midrange to HI, and tweeter to MID.
Once the wiring has been completed, turn on the system
and begin playing a high-quality CD or tape with a wide
musical range. Set the controls on your source unit, equalizer, etc. to their normal listening positions and listen to
the sound of your Reference 6513cs system.
