Crossovers
Low Pass (LPF)
A Low pass lter will allow only
the bass frequencies to reach the
woofer making for a more natural
transition to the higher frequency
drivers. Check your amplier’s
manual for details.
Subsonic
We recommend using an
electronic subsonic lter. This will
help to protect the woofer from
extreme low frequency distortion.
Many ampliers are equipped
with this type lter. Check your
amplier’s manual for details.
Wiring
Connections
This subwoofer is equipped with
quick disconnect type terminals.
Use crimp type terminals or solder
the wire directly to the terminals.
Congurations
Depending on the number of woofers you intend to use,
ayou c n congure the wiring to provide the best impedance

Sealed enclosures offer a range of performance
proles depending on the internal air volume.
Larger enclosures will have a smoother more
extended response while a small enclosure
will have increased output in a more focused
frequency range. Sealed enclosures are the
simplest to construct but do require that the box
be completely air tight.
• Use 3/4” MDF
• Make sure the woofer mounting panel is
full width and height
• Glue all mating surfaces
• Use wood screws
• Use silicone caulk on all internal joints
The internal volume of the
enclosure must be determined
to insure proper performance.
Simply measure height, width and
depth of enclosure you intend
to build. Subtract the material
thickness. Multiply these numbers
and divide by 1728 to get the
volume in cubic feet.
For enclosures with an angled
panel, measure the larger and
smaller depths, add these
together and divide by two. Use
this averaged depth.

Congratulations on your choice of a Hifonics subwoofer.
This “Quick Start Installation” guide is meant to help you
“hook up” and play music.
CAUTION
Always consider consulting a professional audio installer
before installing new subwoofers. High power audio systems
have the ability create sound levels above 130dB. Extended
exposure to high sound pressure levels can cause hearing
damage.
Always run any new wiring through safe areas that wont
interfere with the normal operation of the vehicle.
It’s a good idea to conrm that you have purchased the
correct size subwoofers to t your vehicle. If you have any
reservations about being able to complete the installation
yourself, we recommend contacting a professional. Be careful
as you go. Always disconnect the negative battery terminal
before starting any electrical work on the vehicle.
