Wiring The System - Rockford Fosgate RFX9020 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 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.
6. 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.
7a. 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.
7b. 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.
8. 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.
