Rockford Corporation offers a limited warranty on Rockford Fosgate products on the following terms:
Length of Warranty
Speakers – 1 Year. Any Factory Refurbished Product – 90 days (receipt required)
What is Covered
This warranty applies only to Rockford Fosgate products sold to consumers by Authorized Rockford Fosgate
Dealers in the United States of America or its possessions. Product purchased by consumers from an
Authorized Rockford Fosgate Dealer in another country are covered only by that country’s Distributor and
not by Rockford Corporation.
Who is Covered
This warranty covers only the original purchaser of Rockford product purchased from an Authorized
Rockford Fosgate Dealer in the United States. In order to receive service, the purchaser must provide
Rockford with a copy of the receipt stating the customer name, dealer name, product purchased and date of
purchase. Products found to be defective during the warranty period will be repaired or replaced
(with a product deemed to be equivalent) at Rockford's discretion.

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.
S
AFETY
PRACTICE SAFE SOUND™
Continuous exposure to sound pressure levels over 100dB may
cause permanent hearing loss. High powered auto sound systems
may produce sound pressure levels well over 130dB. Use common
sense and practice safe sound.

VENTED ENCLOSURES
Vented enclosures vary only from the sealed enclosure in that a vent or
port is added to “tune” the enclosure.The enclosures recommended are
designed for great overall performance. Larger boxes tend to be easy to
tune to lower frequencies while medium and small boxes are easier
to tune to higher frequencies.The vented design is less linear in
response than the sealed box but with noticeably more output at
the tuning frequency.
Advantages of vented enclosures:
• Higher average output than sealed
• Tuning frequency can be easily adjusted by changing port length
• Deep bass response with lower power requirements
• Great for high output with limited power

CALCULATING VOLUME
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.
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.

This symbol with “CAUTION” is intended to
alert the user to the presence of important
instructions. Failure to heed the instructions
can result in injury or unit damage.
This symbol with “WARNING” is intended to
alert the user to the presence of important
instructions. Failure to heed the instructions
will result in severe injury or death.
CAUTION To prevent injury and damage to the unit, please
read and follow the instructions in this manual. We
want you to enjoy this system, not get a headache.
CAUTION If you feel unsure about installing this system
yourself, have it installed by a qualified Rockford
Fosgate technician.
CAUTION Before installation, disconnect the battery negative
(-) terminal to prevent damage to the unit, fire
adn/or possible injury.
DESIGN FEATURES
These woofers were designed for use primarily in small ported
enclosures. By utilizing the latest materials and construction techniques,
we are able to offer a speaker with high output at low frequencies while
requiring a minimum of operating space.
NOTE: Vb is the gross volume, which is the TOTAL internal volume, before any speaker and/or port displacement.
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 correct application.

NOTE: The port shown can be placed on any face of the enclosure as long as the port ends are not obstructed.
NOTE: When using vented enclosures, for maximum reliability and power handling ensure that a subsonic or "infrasonic" filter is used so that
only usable low frequency signal is sent to the subwoofer.

WIRING CONFIGURATIONS
By varying the wiring configuration of your speakers you can create an
impedance load to match your system.Altering the wiring configurations
gives a range of options for impedance loads. Series, Parallel, or
Series-Parallel wiring configurations are different techniques for wiring
speakers that provide different loads. Series configuration is a string
method where speakers are wired end to end. Parallel configuration
uses two or more speakers wired across common terminals.
Series-Parallel configuration combines both techniques. Choose the
wiring diagram that corresponds to the number of woofers and the
impedance of your amplifier.
SUBWOOFER CROSSOVERS
There are two operational types of crossovers, passive and active.
Passive crossovers (coils or inductors) are placed on the speaker
leads between the amplifier and speaker.An active crossover is an
electronic filter that separates the audio signal fed to different
amplifiers. For optimum subwoofer performance, we recommend
using an active 80-100Hz low-pass crossover at 12dB/octave.
