installing your new Source Unit. Pre-planning your system layout
and best wiring routes will save installation time. When deciding
on the layout of your new system, be sure that each component
will be easily accessible for making adjustments.
Before beginning any installation, be sure to follow these simple rules:
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. 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.
7. Never run wires underneath the vehicle. Running the wires
inside the vehicle provides the best protection.
8. Avoid running wires over or through sharp edges. Use rubber
or plastic grommets to protect any wires routed through metal,
especially the firewall.
9. ALWAYS protect the battery and electrical system from
damage with proper fusing. Install the appropriate fuseholder
and fuse on the +12V power wire within 18”(45.7 cm) of the
battery terminal.
10. When grounding to the chassis of the vehicle, scrape all paint
from the metal to ensure a good, clean ground connection.
Grounding connections should be as short as possible and
always be connected to metal that is welded to the main body,
or chassis, of the vehicle.

S OURCE U NIT M OUNTING L OCATIONS
The mounting position of your source unit will have a great
effect on the performance of your in-dash 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. Doing so will not only cause severe damage
to your new source unit...but will immediately promote you to
“customer of the month”in our technical support department.
Instrument Panel
Mounting the source unit in the instrument 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 opti-
mum 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 “Instrument Panel”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.

W IRING THE S YSTEM
NOTICE: If you do not feel comfortable with wiring your new
source unit, please see your local Authorized Rockford Fosgate
Dealer for installation.
•For safety, disconnect the negative lead from the battery prior to
beginning the installation.
1. Install the 16-Pin Power Harness by connecting the correspond-
ing wires to the electrical and audio system. Solder and heat
shrink all connections for a reliable installation. For each con-
nection, cut a 1" piece of heat shrink tubing and slide over one
of the 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.
2. Connect the BLACK wire to chassis ground. Prepare the chassis
ground by scraping any paint from the metal surface and thor-
oughly clean the area of all dirt and grease. Strip the end of the
wire and attach a ring connector. Fasten the wire to the chassis
using a non-anodized screw and star washer.
3. Connect the YELLOW wire to a source of constant +12V (for
retaining memory on user-programmed functions). Connect the
Yellow wire to a constant +12 volt positive source. The source
should always have +12V, even when the ignition is off and the
car is not running.
4. Connect the RED wire (Ignition) to a source of switched +12V
(is on only when ignition key is in “accessory”or “run”).
Connect the RED wire to a switched +12 volt positive source.
The switched signal is usually taken from the ACC (accessory)
position of the ignition. If the vehicle does not have an ACC
position, connect the wire to the switched ON position of the
ignition. The current consumption through this wire is negligible.
5. Connect the LT. BLUE wire to the “Remote Turn-On”leads of
the amplifier(s). This will turn-on the external amplifiers when
the source unit is powered on.
6. Connect the BLUE/RED wire to the “Power Antenna”lead. This
will raise a fully automatic antenna when the source unit is
powered on.
7. Connect the B+, GND and Remote Turn on Wires on the 16 pin
harness according to the Installation Reference Sheet.

8. Connect the AUX RCA Jacks to the external audio source (this
inserts the audio before the volume control on the source unit).
The maximum un-clipped input voltage this circuit can accept is
4.0V RMS.
9. *Connect the AUX Video1 and Video2 Jacks to the output of
the external video source(s).
10. Connect the Speaker Wires (if external amplifiers are not used)
to the corresponding speaker leads by soldering and heat shrink-
ing all connections for a reliable installation. If only one pair of
speakers is utilized in the system, use only the FRONT speaker
leads and heat shrink the unused REAR leads to prevent from
shorting out. Be sure to maintain speaker polarity. DO NOT
chassis ground any speaker leads as unstable operation may
result.
11. Install the Preamp Output Harness (if external amplifiers will
be used) by plugging the RCA cables into the corresponding
extension RCAs that feed the input of the amplifiers. Be sure to
route the signal cables away from any high current wires to pre-
vent coupling noise from radiated electrical fields into the audio
signal.
The FRONT RCAs connect to the Front speaker's amplifier.
The REAR RCAs connect to the Rear speaker's amplifier.
The SUM RCAs connect to the Subwoofer amplifier.
The REAR SEAT RCAs connect to the Headphone jacks located
in the rear of the vehicle.
The AUX1 & AUX2* RCAs connect to the output of an auxiliary
audio source.
*The VIDEO1 & VIDEO2 RCAs connect to the output of an
auxiliary video source.
*The VIDEO OUT RCA connects to outboard video monitors.
10. Connect the CD Changer (optional)by plugging the 8-pin DIN
cable into the connector located at the rear of the source unit.
11. Connect the Antenna by plugging the antenna cable into the
connector located at the rear of the source unit. Be sure the
antenna is securely grounded to the vehicle for proper radio
reception.
*Feature available on RFX8350 & RFX8350RDS only
