TUNER
◆ Patented Tuner
TheSourceUnitsutilizearefinedhighperformancetunerforprovid-
ing unmatched tuning range. The tuner uses a patented Digital
Automatic Alignment (a mini pre-programmed computer) to pre-
ciselytargetand“tunein”FMradiostations.Theaftermarketstandard
is done by mechanical alignment which relies on not-so-precise
tunable inductors to “get within the ballpark”of a radio station. The
tuner is also refined with Dual FM Conversion and Dual AM Up-
Convert schemes to create a tuner that is capable of receiving radio
signals better.
THE RESULT: Absolutely the “world's best tuner”
◆MIR Circuit
The MIR (Multipath Interference Rejection) Circuit improves audio
performance under difficult reception conditions. The tuner slowly
tapersfromstereotomonauralwhenexcessivestaticisproduceddue
to poor radio reception in fringe areas. This feature is virtually
undetectablebythelistenerduetoitssmoothtransitionfrommonau-
ralbacktostereo.TheMIRcircuitimprovesaudioqualitybyreducing
multipath effects in both weak and strong signal conditions.
THERESULT:Improvesaudioperformancewhenradioreceptionispoor
TECHNICAL DESIGN FEATURES

◆High Output Voltage/
Low Source Impedance
A high preamp output voltage allows a cleaner signal to be driven to
the amplifier. A low source impedance (50Ω) enables the preamp to
drive multiple amplifiers without signal loss. It is not enough to have
onlyahighvoltageoutput;totakefulladvantageof theextravoltage,
a low source impedance is essential. These two features are an
important combination for a preamp that truly delivers a Punch!
THE RESULT: Resists noise and enables multiple amplifiers to be
driven without signal loss
PREAMP/AMPLIFIER

CD PLAYER
◆Dual 1 Bit D/A Converters with
8x Oversampling
The Digital to Analog (D/A) converter determines the sound quality
of the source unit. 8x oversampling ensures the D/A conversion
occurs at a frequency high enough so information from the digital
conversionis not affected by noise.Thisenables the sound quality to
remain the same as it was in the recording studio.
THE RESULT: Maintains sound quality of CDs
◆Digital Servo Control w/Auto Focus
The Source Unit incorporates a Digital Servo Control to ensure
accurate disc tracking for optimum CD playback. The Auto Focus
feature actually adjusts the laser optics to manufacturing tolerances
of CDs. Imagine a CD player that thinks for itself? That's why the
faceplate says Rockford Fosgate!
THE RESULT: Adjusts to CD manufacturing tolerances for accurate
tracking
◆Hologram Laser w/multi-damping
The Rockford Fosgate CD Players feature high reliability and accu-
racy with the use of a Hologram Laser. The Hologram laser uses a
sophisticated one-piece assembly versus conventional discrete type
lasers that use several mechanical parts. In addition, the multi-
damping system for the CD mechanism acts like rubber shock
absorbers to prevent skipping under rough conditions.

◆Any Button Wake Up
TheAnyButtonWakeUpfeature allowsthereceivertopower-up by
pressing any button on the faceplate or IR remote. If the receiver is
manuallypowereddownwhileignitionpowerison,thereceiverwill
“wakeup”whenanybuttononthefaceplateisdepressed.Thisallows
the user to easily turn on the source unit while simultaneously
demonstrating his/her street racing skills.
THE RESULT: Power-up the receiver without fumbling for the PWR
button
–7 –
◆SMART On (Outputs A & B)
TheSMART On (SequentiallyManagedAccessoryRemoteTurn-On)
outputs supply sequential on/off auto power for external compo-
nents. After the radio is powered on, output “A”will immediately
supply turn-on voltage to its output. A half second later, output “B”
supplies turn-on voltage to its output. After the radio is powered
down, output “B”will immediately turn off, then a half second later,
output “A”will turn off. The SMART On circuitry eliminates turn on/
off transients for components with various power on/off cycles.
THE RESULT: Protects speakers and electronics from damaging
transients
CONTROLS/SECURITY
◆Detachable Faceplate
No need to haul around a five pound source unit wherever you go.
A Detachable Faceplate is a lot easier to remove and carry around
with you. Just press the faceplate release button, drop the faceplate
initscarryingcase,andputitinyourshirtpocket.Now, you'reready
toroll.TheDetachableFaceplateisagreatdeterrenttotheftandhelps
to ensure your CD player is safe …just make sure to remove it.
THE RESULT: Deters source unit theft

◆IR Remote Compatible
(Remote available separately for RFX-8115/8120)
The source unit can be controlled through the use of an IR Remote
Control (RFX-1110). The infrared receiver eye, located inside the
anti-theft faceplate, accepts infrared encoded data from the remote
control.ThisfeatureallowsvariousfunctionsoftheTuner,CDPlayer
and CD Changer to be conveniently operated which will not only
impress your friends but also your favorite car audio judge.
THE RESULT: Ability to operate functions via remote control
◆Pulse
The Pulse provides a momentary +12V to “Output C”of the
source unit. The Pulse is accessible through the “Diamond R”
button on the IR Remote Control (RFX-1110). This function enables
the user to switch on or off additional components connected to the
system.
THERESULT:Abilitytotriggerampracks,neonlights,etc.viaremote
control
◆Cell Phone Mute
The Cell Phone Mute feature automatically mutes the audio system
whenthein-carcellularphonerings.Asensorwireonthesourceunit
detects a signal from the cell phone ringer and triggers audio mute
function. No more missed calls from the office or “significant other”
when cranking up your audio system to escape the pressures of life.
THE RESULT: Nevermissa phonecallwhilelisteningtoyoursystem
◆Source Tone Memory (RFX-8120/8130/8140)
The Source Tone Memory function memorizes the bass and treble
setting between AM, FM, CD, CD Changer and External Audio
modes. This enables the user to customize or compensate for the
difference in sound between multiple source modes.
THE RESULT: Separate Bass and Treble memory for different modes

best wiring routes will save installation time. When deciding on the
layoutofyournewsystem,besurethateachcomponentwillbeeasily
accessible for making adjustments.
Beforebeginninganyinstallation,besuretofollowthesesimplerules:
1. Be sure to carefully read and understand the instructions before
attempting to install the Source Unit.
2. For safety, disconnect the negative lead from the battery prior to
beginning the installation.
3. For easier assembly, we suggest you run all wires prior to
mounting your Source Unit in place.
4. Route all of the RCA cables close together and away from any
high current wires.
5. Use high quality connectors for a reliable installation and to
minimize signal or power loss.
6. Thinkbeforeyoudrill! Becarefulnottocutordrillintogastanks,
fuel lines, brake or hydraulic lines, vacuum lines or electrical
wiring when working on any vehicle.
7. Never run wires underneath the vehicle. Running the wires
inside the vehicle provides the best protection.
8. Avoid running wires overor through sharp edges. Userubber or
plastic grommets to protect any wires routed through metal,
especially the firewall.
9. ALWAYS protect the battery and electrical system from damage
withproperfusing. Installtheappropriatefuseholderandfuseon

SOURCE UNIT MOUNTING LOCATIONS
The mounting position of your source unit will have a great effect on
the performance of your CD Player. The source unit can be installed
in a wide range of operating locations. However, care should be
taken to ensure optimum performance.
Engine Compartment
Mounting the source unit in the engine compartment will void your
warranty. The only thing that should be mounted in the engine
compartment is that big metal thing that makes the vehicle go fast.
Instrument Panel
Mountingthesourceunitintheinstrument panel provides optimum
access. The source unit should be securely mounted using the
“Standard Mount”or “ISO Mount”method to ensure optimum CD
Player performance.
Center Console
Mounting the source unit in the center console provides optimum
access. Be sure the installation does not interfere with the operation
of the gear shift or parking brake. The source unit should have a
mounting angle within ±20°from horizontal.
Glove Box
Mounting the source unit in the glove box is adequate, but does not
provide easy access. Glove box mounting should only be done if
“InstrumentPanel”or ”Center Console,”mounting is not acceptable
(i.e., maintaining integrity of older vehicles with metal dashboards.)
The source unit should be mounted within ±20°from horizontal.
Under Dash
Mounting the source unit under the dash is adequate, but does not
provide easy access. Under dash mounting should only be done if
“Instrument Panel,””Center Console”or ”Glove Box”mounting is
not acceptable. Mount the source unit off to the side of the driver's
area to reduce interference with the parking brake, gear shift, or
operating pedals. The source unit should be mounted within ±20°
from horizontal.

NOTICE: If you do not feel comfortable with wiring your new
source unit, please see your local Authorized Rockford Fosgate
Dealer for assistance.
•For safety, disconnect the negative lead from the battery prior to
beginning the installation.
1. Installthe22-Pin/PowerHarnessbyconnectingthecorrespond-
ing wires to the electrical and audio system. Solder and heat
shrinkallconnectionsforareliableinstallation.Foreachconnec-
tion,cuta1" pieceofheat shrinktubingandslideoveroneofthe
wires. Strip each wire 3/8" then twist together and solder. Slide
the tubing over the connection and shrink the tubing with a hot
air gun until no bare wire is exposed.
The BLACK Wire (Chassis Ground) supplies power ground for
thesourceunit.Preparethechassisgroundbyscrapinganypaint
from the metal surface and thoroughly clean the area of all dirt
andgrease. Strip the endofthe wire and attacharing connector.
Fasten the wire to the chassis using a non-anodized screw and
star washer.
The RED Wire (Ignition) allows the source unit to turn on only
when the ignition key is in the “accessory”or “run”position.
Connect the RED wire to a switched 12 volt positive source . The
switched signal is usually taken from the ACC (accessory) posi-
tionoftheignition. Ifthe vehicledoes nothave anACC position,
connectthewiretotheswitchedONpositionoftheignition.The
current consumption through this wire is negligible.
TheYELLOW Wire (Battery) is the main power wire and retains
memory for user-programmed functions. Connect the Yellow
wire to a constant 12 volt positive source . The source should
alwayshave+12V,evenwhentheignitionisoffandthecarisnot
running.
TheLT.BLUEWire(Turn-On“A”)istheprimaryaccessoryturn-
on wire which provides immediate turn-on and .5 sec delayed
turn-off. Connect the Lt. Blue wire to the “Remote Turn-On”
leads of any external equalizers or crossovers which cause on/
off transients (pops or thumps) in the system. The maximum
current available from this lead is 2 Amps.

The BLUE/WHITE (Turn-On “B”) is the secondary accessory
turn-on wire which provides a .5 sec delayed turn-on and
immediate turn-off. Connect the Blue/White wire to the “Re-
mote Turn-On”leads of the amplifiers. The maximum current
available from this lead is 300mA.
The BLUE/RED Wire (Turn-On “C”) is the pulsed 500ms
output accessible through the “Diamond R”button on the IR
Remote. Connect the Blue/Red wire to a latching relay or
circuit which will be used to turn on and off accessories such
asneonlights,ampracks,etc.Themaximumcurrentavailable
from this lead is 300mA.
The BROWN Wire (Audio Mute) mutes the audio for cellular
phone use. Most cellular phones provide an output which is
usedtobeep-beepthevehicle'shornormutetheaudiosystem.
Connect the Brown wire to the cellular phone's “–” output. If
thecellularphoneisa“+”triggeroutput,usearelayto“chassis
ground”the Brown wire.
*The GREEN/WHITE Wire (External Audio Control) triggers
theselectionoftheExternalAudioInput(ExternalAudioInput
#2 for 8140). Connect the Green/White wire to a relay or
switch that will provide a constant “chassis ground”when
selected.The Externalaudio Inputwillcontinue tooverride all
other functions (Tuner, CD, CD Changer) for the duration that
the Green/White wire is connected to “chassis ground.”
NOTE:SincetheExternalAudioInputandtheCDChangeruse
the same 13-pin DIN connector, only one component can be
supported at a time.
*The ORANGE Wire (Dimmer) is used for the source unit's
illuminationdimmer.ConnecttheOrangewiretothe“parking
light”or a switched 12 volt positive source. The current
consumptionthroughthiswireisnegligible.Refertothe“Basic
Operation”section of this manual for further information.
* Feature available on select models.

*The ORANGE/WHITE Wire (External Dimmer) allows the
source unit to control the illumination level of compatible
Rockford Fosgate components. Connect the Orange/White
wire to the dimmer input (typically orange wire) of the addi-
tional Rockford Fosgate component.
CAUTION! The Orange/White wire uses Pulse Width Modu-
lation(not rheostat design) to control the level of illumination
for RF components only.
*The BLUE Wire (Power Antenna) is used to control only fully
automatic antennas. Since the antenna is specially controlled
throughoutthedifferentoperatingconditionsofthesourceunit,
it is recommended to use the Blue wire from the source unit
instead of the factory power antenna control wire. If this is
desired, disconnect the “+”control lead from the power an-
tenna and heatshrink it to prevent it from shorting out. Then
connect the Blue wire to the “+”control lead of the power
antenna.
*The Signal Processor Loop is used to insert a signal processor
before the volume control on the source unit. The GREEN
marked RCAs are the SPL input –the output of the signal
processor should connect to these inputs. The GRAY marked
RCAs are the SPL output –the input of the signal processor
should connect to these outputs.
2. *ConnecttheSpeakerWires(ifexternalamplifiersarenotused)
to the corresponding speaker leads by soldering and heat
shrinking all connections for a reliable installation. If only one
pair of speakers is utilized in the system, use only the FRONT
speakerleadsandheatshrinktheunusedREARleadstoprevent
from shorting out. Be sure to maintain speaker polarity. DO
NOT chassis ground any speaker leads as unstable operation
may result.
3. Take a break! Youdeserve a nice cold one after wiring that 22-
pin harness.
