*The Exonic “Extreme” 10X and 12X subwoofers can be used in a wide

range of enclosure sizes. The specified sizes reflect both sound quality

and high output usage. For those in need of extreme SPL designs,

requiring higher tuned enclosures, please contact your local Authorized

Dealer or call Ample Audio direct.

**All of the specified enclosures can be categorized as Optimum or

Recommended sizes. However, the performance of these enclosures

may vary due to vehicle type and amplifier power. In addition, properly

designed and built enclosures are necessary for exceptional speaker per-

formance. Your local Authorized dealer or an Ample Audio technical

support person can assist with any questions you may have.

Enclosure Types

The three most common enclosures used in the mobile audio environment

are;

sseeaalleedd,, vveenntteedd ((ppoorrtteedd))

, or

bbaannddppaassss

. Each one of these enclosures has

certain characteristics that may or may not suit your needs. In order to

choose the correct enclosure for your system, it will be necessary to

answer a few questions.

One of the most important questions is space. How much area do you

have to work with? Second, you need to know how much power your

amplifier can produce continuously. Next, decide what kind of bass you

want, tight, boomy, punchy, high sound quality, or extreme sound pressure

(SPL). Finally, decide who is going to build your box and if you will be the

wood chuck that does the work, make sure you choose a box that is not

to difficult for your skill level.

When building your enclosure or if you have a professional build it, make

sure the correct materials are used. Ample Audio recommends the use of

Medium Density Fiberboard (MDF) as the primary construction materi-

al, a high grade wood glue, premium pure silicone for sealing seams, solid

wood braces for large or high pressure enclosures, high quality fasteners

for assembly (pre-drilled and screwed for high pressure applications or

heavy gauge nailer brads for less demanding enclosures), high quality

speaker terminals, box filler when applicable, and always make sure that

the mounting area is flat and the woofer hole is the proper diameter.

The easiest type of box to build is a “Sealed Enclosure.” Sealed enclosure

offer smaller air space, good power handling at all frequencies, linear

response, and they tend to have exceptional sound quality.

When building a sealed enclosure, make sure that all of the seams are air-

tight by using a high-grade silicone. Sealed enclosures are generally cate-

gorized for tight or high sound quality applications. If the box volume is

increased, the bass will become deeper and will have a flatter response. If

you want to generate more SPL, simply make the box smaller than rec-

ommended, but keep in mind that the overall response will be inferior.

Vented (ported) enclosures are a little trickier to design and build than

sealed enclosures, but they can offer several advantages as well. The use

of vented enclosures requires 50% to 150% more space; therefore you have

to first determine whether or not you are willing to give up the room in

your vehicle or if you have enough room at all. The reasons why vented

enclosures are harder to design is because they are dependent upon a tun-

ing port. If the port size is to small or to large, the output will be very lim-

ited and there is a strong possibility that you will damage the woofer. If

the port is properly done, there can be a significant increase in output ver-

sus other types of enclosures. Other benefits include excellent deep bass

response, lower power requirements (more efficient), and extreme SPL.

Use vented enclosure for extended deep bass or strong punch.

The most difficult enclosure to design and build is known as a bandpass

box. Described by its name, a bandpass box controls both low and high fre-

quencies. These enclosures are very unique because they allow the

designer to control efficiency. Usually, however, BP boxes require the

most amount of space and cost the most to build. There are many varia-

tions to bandpass enclosures, therefore, it is usually a good idea to consult

your Authorized Dealer or call Ample Audio for designs. However, we

have included a dual chamber, single woofer design for those who want to

attempt a BP design.

Recommended Enclosures

Please note that all enclosure volumes include displacement for speaker

and port. Do not add to these measurements. Sealed and ported enclo-

sures, as well as the sealed chamber (Vb1) on all bandpass enclosures

should be lined on 3 walls with 1.75” to 2.5” thick Dacron or Pollyfill

material. The ported (Vb2) chamber on all bandpass enclosures can be

lined on 1 or 2 walls. Do not restrict any port area with filler.

Wiring Guide

All

AAmmppllee AAuuddiioo

subwoofers use dual 4 ohm voice coils. The use of dual

4 ohm voice coils makes these woofers very versatile, but a little trickier

to wire. Please pay close attention to the following guidelines.

It is very important to know the limits of your amplifier and how to

properly wire your woofers to match. Most amplifiers today are stable

into 2 ohm stereo or 4 ohm mono/bridged. There are also some amps that

are stable down to 1/2 ohm. Mono is a term used to describe the

combining of both left and right audio signals and bridged describes

the combining of power into one channel. It is always a good idea to use

your woofers in a mono/bridged mode, if your amplifier has this

capability. Almost all Owners Manuals will list the amplifiers load rating,

so please check before deciding how to wire your speakers.

There are three different types of wiring configurations used in car audio.

They are described as, series, parallel, and series-parallel. You can change

the impedance or “load” depending on the quantity of woofers and how

they are wired. Please use the diagrams bellow to help choose the proper

wiring configuration for your system.

Introduction

Thank you for choosing an

AAmmppllee AAuuddiioo

subwoofer. All

AAmmppllee AAuuddiioo

products are designed and manufactured to meet the highest possible

standards in order to give you many years of musical enjoyment.

This manual is intended to provide the necessary information needed to

properly incorporate your new

AAmmppllee AAuuddiioo

subwoofer into any mobile

audio system.

There are three different series, consisting of eight different models

contained in this manual. It is necessary to pay close attention to your

specific woofer when deciding on a particular enclosure. Failure to use

the correct enclosure will result in lower power handling and poor sound

quality.

Please take the time to carefully read your Owners Manual; it’s the key

to musical success.
