Congratulations on your choice of a Hifonics subwoofer.

This “Quick Start Installation” guide is meant to help you “hook up” and play music. For more detailed information

on system setting, speaker and subwoofer conguration,

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.

Subwoofer dimensions

Before you start

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.

Enclosure types

Sealed

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.

Vented

Vented designs offer the ability to tune the enclosure. Larger enclosures will have a smoother more extended response while a small enclosure will have increased output in a more focused frequency range. Vented enclosures are more difcult to construct but offer more overall output.

Volume calculation

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.

Enclosure construction

• 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

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.

2Ohm DVC Congurations

Depending on the number of woofers you intend to use, you can congure the wiring to provide the best impedance load for your system. Below are some examples. Consult your amplier’s manual for recommendations.

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 push and insert type terminals. Strip back 1/2” wire insulation. Push down on the terminal, then insert the wire and release.
