Thank you for your purchase of the Orion Cobalt Subwoofers. These woofers
represent a combination of incredible performance and value. We at Orion strive to
give you the latest up to date information about this product. What we can’t give you
with the manual is personal installation or technical experience. If you have questions
concerning the use or application of this product please refer to the nearest ORION
dealer for assistance, visit www.orioncaraudio.com, or call the 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.
Included in this box are all the necessary mounting hardware and cables for your basic
installation. Listed below is a detailed list of the components included in this system
package.
The performance of these Cobalt subwoofers is directly proportional to the quality
of the installation. Care taken with the installation process will be rewarded by
years of satisfying performance. If you are unsure of your installation abilities, please
refer to your local authorized ORION dealer for 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 the installation. .
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 and assorted Bits
• Phillips Screwdriver • Wire Strippers
• Allen Wrenches • Volt/Ohm Meter (Optional)
• Table Saw • Jig Saw
• Wire Cutters • Wire Crimpers
FINDING SPEAKER MOUNTING LOCATIONS
Choosing the correct speaker locations will have the greatest effect on the
sound quality of the system. Different considerations are 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. If minimal intrusion in your vehicle is desired, factory
speaker locations may be the ticket for you. These woofers are too large to fit most
factory locations and typically need enclosures to perform correctly.

The following illustrations provide guidelines on properly connecting your
Orion Cobalt woofer to an Orion Cobalt amplifier for maximum performance.
Recommended Amplifier Power
Continuous Power (RMS)Peak Power (Watts)
1 woofer100 to 300200 to 600
2 woofers200 to 600400 to 1200
3 woofers300 to 900600 to 1800
4 woofers400 to 1200800 to 2400
Parallel—Two Speakers ( 4 ohm voice coils)
Two 4 ohm voice coil woofers with the two woofers in parallel results in a 2 ohm load
to the amplifier..
1. Connect the speaker in parallel by connecting the two positive (+) terminals
together and the two negative (-) terminals together.
2. Wire the positive (+) terminals of the woofers to the positive (+) terminal on
the amplifier. Wire the negative (-) terminals of the woofers to the negative (-)
terminal on the amplifier.
One 4 ohm voice coil woofer results in a 4 ohm load to the amplifier.
1. Connect the speaker by connecting the positive (+) terminal of the woofer to
the positive (+) terminal on the amplifier. Wire the negative (-) terminal of the
woofer to the negative (-) terminal on the amplifier.
Two single 4 ohm voice coil subwoofers with the voice coils connected in series to
result in an 8 ohm load to the amplifier.
1. Connect the woofers in series by connecting the negative (-) terminal of the first
woofer voice coil to the positive (+) terminal of the second woofer voice coil.
2. Wire the positive (+) terminal of the first woofer voice coil to the positive (+)
terminal on the amplifier. Wire the negative (-) terminal of the second woofer
voice coil to the negative (-) terminal on the amplifier.
4 single 4 ohm voice coil subwoofers with the voice coils of each pair of speaker wired
in series and then all 4 speakers wired in parallel to result in a 4 ohm load on the
amplifier.
1. Connect the negative (-) terminal from speaker 1 to the negative terminal on
speaker 3 and then hook that wire to the negative (-) terminal on the amplifier.
2. Connect the positive (+) terminal from speaker 1 to the negative (-) terminal on
speaker 2.
3. Connect the positive (+) terminal from speaker 3 to the negative (-) terminal on
speaker 4.
4. Connect the positive (+) terminal from speaker 2 to the positive (+) terminal on
speaker 4 and then hook that wire to the positive (+) terminal on the amplifer.
