Installation Considerations

The following is a basic list of tools needed for installation:

• Volt/Ohm meter

• Wire strippers

• Wire crimpers

• Wire cutters

• #2 Phillips screwdriver

• Heat shrink tubing

• Soldering iron

• Solder

• Heat gun

• 7mm wrench

• Battery post wrench

• Hand held drill w/ assorted bits

This section focuses on some of the vehicle considerations for 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.

If you feel unsure about installing this system yourself, have it installed by a qualiﬁed Rockford Audio technician.

Before installation, disconnect the battery negative (-) terminal to prevent damage to the unit, ﬁre and/or possible injury.

Before beginning any installation, follow these simple rules:

1. Be sure to carefully read and understand the instructions before attempting to install the 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 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 fuse holder 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. Seatbelt bolts should never be used for connecting to ground.

Mounting (Using Mounting Plate)

To mount the unit, you will need to ﬁnd a ﬂat surface with adequate clearance behind it that provides enough clearance for the unit and all it’s necessary wiring.

1. Once you have determined a mounting location, you will need to cut a circular hole 3” (77mm) in diameter.

2. After the hole is cut slide the unit and wiring through the hole.

3. Slide the mounting plate over the backside of the unit and secure with the supplied screws.

4. Press on the trim bezel to the front side of the unit.

5. Plug in all wiring harnesses and cables. Refer to the wiring diagram for wire harness connection types.

2. After the hole is cut slide the unit and wiring through the hole.

3. Take the U bracket and slide over the two studs on the back of the unit. Tighten down with supplied nuts.

4. Press on the trim bezel to the front side of the unit.

5. Plug in all wiring harnesses and cables. Refer to the wiring diagram for wire harness connection types.
