PRACTICE SAFE SOUND
Continuous exposure to sound pressure levels over 100dB may
cause permanent hearing loss. High powered auto sound systems
may produce sound pressure levels well over 130dB. Use common
sense and practice safe sound.
PRATIQUEZ UNE ÉCOUTE SANS RISQUES
Une exposition continue à des niveaux de pression acoustique
upérieurs à 100 dB peut causer une perte d’acuité auditive
permanente. Les systèmes audio de forte puissance pour auto
peuvent produire des niveaux de pression acoustique bien au-delà
de 130 dB. Faites preuve de bon sens et pratiquez une écoute sans
risques
PRACTIQUE EL SONIDO SEGURO
El contacto continuo con niveles de presión de sonido superiores
a 100 dB puede causar la pérdida permanente de la audición. Los
sistemas de sonido de alta potencia para automóviles pueden
producir niveles de presión de sonido superiores a los 130 dB. Aplique
el sentido común y practique el sonido seguro.
PRAKTIZIEREN SIE SICHEREN SOUND
Fortgesetzte Geräuschdruckpegel von über 100 dB können beim
Menschen zu permanentem Hörverlust führen. Leistungsstarke
Autosoundsysteme können Geräuschdruckpegel erzeugen, die weit
über 130 dB liegen. Bitte wenden Sie gesunden Menschenverstand an
und praktizieren Sie sicheren Sound.
OSSERVATE LE REGOLE DEL SUONO SENZA PERICOLI
La costante esposizione a livelli di pressione acustica al di sopra dei
100dB possono causare la perdita permanente dell’udito. I sistemi
audio ad alta potenza possono produrre livelli di pressione acustica
ben superiori ai 130dB. Si consiglia il buon senso e l’osservanza delle

OPTIMAL ENCLOSURE
Infinite Bale
An Infinite Bale enclosure design represents an application where
the compliance of the air volume within the enclosure is greater than
the compliance on the speaker’s suspension (Vas). An infrasonic filter
is required for reliable performance.
Infinite Bale 10”
F3- 3dB Point (Hz) 49.2
Vas - cu. . (Liter) 1.56
(44.2)
Qtc - Enclosure Damping 0.74
IMPORTANT: A subsonic or “infrasonic” filter at or above the
resonant frequency (Fs) of the speaker is required.
NOTE: Infinite bale installations will result in lower speaker
power handling when compared to fully enclosed applications
such as sealed or vented enclosures.
Wiring Configurations
By varying the wiring configuration of your speakers you can create
an impedance load to match your system. Altering the wiring configu-
rations gives a range of options for impedance loads. Series, Parallel,
or Series-Parallel wiring configurations are dierent techniques for
wiring speakers that provide dierent loads. Series configuration is a
string method where speakers are wired end to end. Parallel configu-
ration uses two or more speakers wired across common terminals.
Series-Parallel configuration combines both techniques. Choose the
wiring diagram that corresponds to the number of woofers and the
impedance of your amplifier.
Subwoofer Crossovers
There are two operational types of crossovers, passive and active.
Passive crossovers (coils or inductors) are placed on the speaker
leads between the amplifier and speaker. An active crossover is an
electronic filter that separates the audio signal fed to dierent ampli-
fiers. For optimum subwoofer performance, we recommend using an
active 80-100Hz low-pass crossover at 12dB/octave.

NOTE: The port shown can be placed on any face of the enclosure as

NOTE: When using vented enclosures, for maximum reliability and
power handling ensure, that a subsonic or “infrasonic” filter is used
so that only usable low frequency signal is sent to the subwoofer.

Installation Considerations
Before beginning any installation, follow these simple rules:
1. Be sure to carefully read and understand the instructions
before attempting to install these speakers.
2. For easier assembly, we suggest you run all wires prior to
mounting your speakers in place.
3. Use high quality connectors for a reliable installation and
to minimize signal or power loss.
4. Think before you drill! Be careful not to cut or drill into gas
tanks, fuel lines, brake or hydraulic lines, vacuum lines or
electrical wiring when working on any vehicle. If installation
in a boat, take care not to cut or drill through the main hull.
5. Never run wires underneath the vehicle. Running the wires
inside the vehicle or hull area provides the best protection.
6. Avoid running wires over or through sharp edges. Use
rubber or plastic grommets to protect any wires routed
through metal, especially the firewall.
Mounting
1. Determine where the speakers will be mounted. Ensure an
area large enough for the speaker to mount evenly. Be sure
that the mounting location is deep enough for the speaker
to fit; if mounting in a door, operate all functions (windows,
locks, etc.) through their entire operating range to ensure
there is no obstruction.
2. Refer to the specification chart to determine the proper
diameter hole to cut for your speaker model. Cutting and
mounting templates can be found at www.rockfordfosgate.
com.
3. Mark the locations for the mounting screws. Drill the holes
with a 1/8” bit.
4. Feed the speaker wires through the cutout and connect to
the speaker terminals. Be sure to observe proper polarity
when connecting the wires. The speaker’s positive terminal
is indicated with a “+”.
5. Fit the trim ring over the speaker and mount into place
using the four (4) screws that are provided.
6. Tighten the screws until the speaker is snug in place to
prevent rattling. Do not over tighten the screws.

COLOR OPTIX™ Wiring Precautions
• Do not connect to 24 Volt electrical systems
• We recommend only using the COLOR OPTIX™ wiring chart
or connecting to the PMX-RGB. Connecting any other way
could cause damage to the speakers or the device you have
connected to.
• We recommend installing a fuse (not included) on the
Yellow 12 Volt wire whenever you are NOT using the PMX-
COLOR OPTIX™. See COLOR OPTIX™ wiring chart for wiring
options.
• Rockford recommends a minimum of 20 gauge wire when
hard wiring your COLOR OPTIX™ speakers.
• Never wire the COLOR OPTIX™ lights directly to 12 volts.
Utilize either the PMX-RGB or a toggle switch (not included)
connected to a fused 12 volt power supply. Refer to the
specification to determine the size of fuse (not included)
needed
