INTRODUCTION

Thank you for your purchase of the Orion HCCA SubWoofers. These woofers
represent a combination of incredible performance and value. The HCCA series
subwoofers feature a massive 4" voice coil and triple stacked magnet assembly to
maximize excursion and output. Capable of maintaining their balance at
exceptionally high output levels. These high-performance woofers are built with dual
2 or 4 ohm voice coils, to get the most out of your amplifier. They are available in
standard 10”, 12” and 15” sizes.

We at Orion strive to give you all the latest up to date information about this product.
What we can’t give you in this manual is personal installation or technical experience.
If you have questions concerning the use or application of this product, please refer
to the nearest Authorized ORION Dealer for assistance, visit www.orioncaraudio.com,
or call the Orion technical support hotline at 1-800-876-0800. As we are always
finding new ways to improve our product, the features and specifications are subject
to change without notice.

PRACTICE SAFE SOUND™

Continuous exposure to sound pressure levels over 100dB may cause permanent
hearing loss. High powered automotive sound systems can generate sound pressure
levels in excess of 130dB. When playing your system at high levels, please use hearing
protection and prevent long term exposure.

INSTALLATION

The performance of these HCCA subwoofers is directly proportional to the quality of
installation. Care taken during the installation process will be rewarded with years of
satisfying performance. If you are unsure about your installation capabilities, please
refer to your local Authorized Orion Dealer for technical assistance. Orion dealers are
trained professionals dedicated to extracting the maximum performance out of your
Orion system. If you decide to install this speaker system yourself, please read the
entire section on sealed and vented enclosures before starting your installation.

Please Note: Due to the extremely long excursion and high temperature possibilities
of this woofer, it is recommended that when the woofer is installed it be positioned
so that the cone either faces upward or downward only.

TOOLS OF THE TRADE

Listed are the majority of the tools required to perform the installation. Having the
proper tools will make the installation much easier. It is very difficult when you get
half way through the installation and discover that you require a specific tool to get
yourself through a particular part of the installation. Some of these tools are
necessities. Some make the job much easier.

• Marking Pen • Electric Drill

• Assorted Drill Bits • Phillips Screwdriver

• Allen wrenches • Volt/Ohm Meter (Optional)

• Wire Strippers • Wire Cutters

• Table saw • Wire Crimper

• Jig saw

FINDING SPEAKER MOUNTING LOCATIONS

Choosing the correct speaker locations will have the greatest effect on the sound
quality of the system. There are many different considerations needed when choosing
the locations that best suit your needs. The locations must be large enough for the
speakers to fit. Care is needed to ensure that the location you have chosen will not
affect any of the mechanical or electrical operations of the vehicle.

Determining the best location for the speakers will depend on your cosmetic needs
and your vehicle's interior. Usually the woofers are installed in the trunk, rear seat, or
rear of the vehicle.

ENCLOSURE DESIGN

This section gives the basic description for a sealed enclosure. Orion HCCA woofers
are designed for sealed enclosures and vented enclosures. Sealed enclosures are
generally considered the most versatile for all music types and are the easiest to
build. They will also give high power handling with a wider range of frequencies.
The enclosure must be absolutely air tight. Use a high quality wood glue for all
seams of the enclosure. The enclosure should also be screwed together. The
enclosure should be no less than 3/4" on sides. The baffle board (woofer mounting
plate) should be no less than 1". If the woofer mounting is to be recessed then a
minimum of two 3/4" plates together should be used. As MDF is a porous material
it is best to also seal the inside of the enclosure.

NOTE: The woofer must face up or down only, especially in sealed enclosures.

NOTE: Refer to the website www.orioncaraudio.com for updated enclosure

data for your woofer application.

Enclosure Details

1. Parameters listed are for conventional applications only, for further help please call Tech Audio Support

2. 1" MDF is recommended.

3. Recommended enclosures are NET Box Volumes, speaker and port displacement are calculated into the
volume of the enclosure, you will not need to add these volumes to calculate GROSS volume for the
enclosure.

*** Sub-sonic filters should always be used and adjusted specifically for vented box designs.
NOTE: The woofer must face up or down only, especially in sealed enclosures.
