Sealed Enclosures
Sealed enclosures are the simplest to build. The most important part of
building a sealed enclosure is to make sure that the enclosure is airtight.
Using glue and some type of sealant on all seams will ensure solid
construction and prevent air leaks. The box volume will directly impact the
performance of the speaker. Larger enclosures will provide flatter response
and deeper bass whereas smaller boxes will provide a bump in the response
curve and generally higher output for greater SPL.
Advantages of sealed enclosures:
- Small enclosures
- Linear (Flat) response
- No port noise
- High power handling at all frequencies
- Excellent for sound quality
- Extended low-frequency output when compared to vented enclosures
Building an Enclosure
To work properly, the walls of the enclosure must be rigid and not flex when
subjected to the high pressures generated by the speaker’s operation. For
optimum performance, we recommend using 3/4” MDF (Medium Density Fiberboard)
and internal bracing. The enclosure should be glued together and secured with
nails or screws.
Calculating Volum e
Calculating volume is merely a matter of measuring the dimensions in inches
and using the formula: H x W x D divided by 1728 (cubic feet). See block
below.
| Box Volume | Height” x Width” x Depth” |
|---|---|
| Divided by (cubic feet) | 1728 |
If two facing sides are of uneven length, add them together and divide by two to take the average. Using this number will give you the volume without the necessity of calculating the box in sections and adding the sections together. The thickness of the baffle material reduces the internal volume so this must be subtracted from the outside dimensions to determine the internal volume. The speaker itself also reduces the internal volume. The amount of air displaced by each model is listed on the specification sheet and should also be subtracted from the gross volume calculation.
Sealed Enclosure
NOTE: Vb is the internal volume before any speaker displacement is added.
All external dimensions were based on the use of 3/4” (1.90cm) materials.
NOTE: When using enclosures other than recommended, call Technical Support for the correct application.

Installation Considerations
Before beginning any installation, follow these simple rules:
-
Be sure to carefully read and understand the instructions before attempting to install these speakers.
-
For easier assembly, we suggest you run all wires prior to mounting your speakers in place.
-
Use high-quality connectors for a reliable installation and to minimize signal or power loss.
-
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. If installation
in a boat, take care not to cut or drill through the main hull. -
Never run wires underneath the vehicle. Running the wires inside the vehicle or hull area provides the best protection.
-
Avoid running wires over or through sharp edges. Use rubber or plastic grommets to protect any wires routed through metal, especially the firewall.
Mounting
-
Determine where the speakers will be mounted. Ensure an area large enough for the speaker to mount evenly. Be sure that the mounting location is deep enough for the speaker
to fit; if mounting in a door, operate all functions (windows, locks, etc.) through their entire operating range to ensure there is no obstruction. -
Refer to the specification chart to determine the proper diameter hole to cut for your speaker model. Cutting and mounting templates can be found at www.rockfordfosgate.com.
-
Mark the locations for the mounting screws. Drill the holes with a 1/8” bit.
-
Feed the speaker wires through the cutout and connect to the speaker terminals. Be sure to observe proper polarity when connecting the wires. The speaker’s positive terminal
is indicated with a “+”. -
Fit the trim ring over the speaker and mount it into place using the four (4) screws that are provided.
-
Tighten the screws until the speaker is snug in place to prevent rattling. Do not over-tighten the screws.
Wiring
SPEAKER Wiring
There are (2) different options for wiring your speakers. You can also utilize
the DEUTSCH™/Amphenol style connector (not included) input next to the COLOR
OPTIX™ connector.
COLOR OPTIX™ Wiring
If not using the PMX-RGB, follow the diagrams below for proper pin-out and
hard wiring instructions. COLOR OPTIX™ Wiring Precautions
-
Do not connect to 24 Volt electrical systems
-
We recommend only using the COLOR OPTIX™ wiring chart or connecting to the PMX-RGB. Connecting any other way could cause damage to the speakers or the device you have connected to.
-
We recommend installing a fuse (not included) on the Yellow 12 Volt wire whenever you are NOT using the PMXCOLOR OPTIX™. See COLOR OPTIX™ wiring chart
for wiring options. -
Rockford recommends a minimum of 20 gauge wire when hard wiring your COLOR OPTIX™ speakers.
-
Never wire the COLOR OPTIX™ lights directly to 12 volts. Utilize either the PMX-RGB or a toggle switch (not included) connected to a fused 12-volt power supply. Refer to the specification to determine the size of the fuse (not included) needed
