Wiring The System - Rockford Fosgate RFX9220M Installation & Operation Manual

WIRING THE SYSTEM

NOTE: See diagram on following page to help you connect your system.
CAUTION: If you do not feel comfortable with wiring your new source unit, please see
your local Authorized Rockford Fosgate Dealer for installation.
CAUTION: Before installation, disconnect the battery negative (-) terminal to prevent
damage to the unit, fire and/or possible injury.
1. Install the 16-Pin Power Harness by connecting the corresponding wires to the electrical and audio
system. Solder and heat shrink all connections for a reliable installation. For each connection, 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 (Ground) wire to chassis ground. Prepare the chassis ground by scraping any paint
from the metal surface and thoroughly 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 (Backup) wire to a source of constant +12V (for retaining memory on user-
programmed functions).The source should always have +12V, even when the ignition is off and the car is
not running.
4. Connect the RED (ACC +B) wire (Ignition) to a source of switched +12V (is on only when ignition key
is in "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) position of the ignition. If the vehicle does not
have an ACC position, connect the wire to the switched ON position of the ignition.
5. Connect the ORANGE (Dimmer) wire to the lighting switch terminal.This will dim the main display by
30% when the headlights are turned on.
6. Connect the LT. BLUE (Remote B+) 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.
7. Connect the BLUE/RED (Auto Ant.) wire to the "Power Antenna" lead.This will raise a fully automatic
antenna when the source unit is powered on, but only in Tuner Mode.
8. Connect the PINK (Telephone Mute) wire for cell phone mute to the wire on the cell phone harness
that provides ground when the phone rings.
9a. Connecting Speakers (Not using external amplifier)
Connect the Speaker Wires 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 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.
9b. Connecting Speakers (Using external amplifier)
Install the Preamp Output Harness 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 prevent coupling noise from radiated electrical fields into the audio signal.The FRONT OUTPUT
connects to the Front speaker's amplifier.The REAR OUTPUT connects to the Rear speaker's
amplifier.The SUM OUTPUT connects to the Subwoofer amplifier.
10. Connect the AUX INPUT to the external audio source (this inserts the audio before the volume
control on the source unit).The input voltage this circuit can accept is 1–3V RMS.
11. Connect the CD Changer (optional) by plugging the 8-pin DIN cable into the connector located at the
rear of the source unit. DO NOT connect the optional Wired Remote into this connector.
12. Connect the Wired Remote (optional) by plugging the 8-pin DIN controller cable into the pigtail
connector hanging from the rear of the source unit. DO NOT connect the optional CD Changer into
this connector.
13. 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.
