LIMITED WARRANTY STATEMENT

Diamond Audio Technology, Inc. (DAT) warrants all DAT products to be free of
defects in material and workmanship for a period of one (1) year from the date
of original purchase provided they are purchased from an authorized DAT
retailer in the United States. However, the effective warranty period will be
three (3) years if the products were purchased from and installed by an
authorized DAT retailer.

What is covered: Parts and labor to effect repair or, at the sole discretion of
DAT, replacement of either any malfunctioning or defective part(s) or the entire
system should the system or any component part(s) thereof fail to perform as
designed. Includes return freight via ground transportation to destinations
within the United States.

What is NOT covered: Installation or setup and repair or replacement of the
system or any parts thereof which, in DAT’s judgment, fail or become damaged
as a result of negligence, improper use, abuse, unauthorized modification or
service, improper or inadequate packaging during shipment, installation by a
non-authorized dealer, accident, or use for any purpose other than those for
which this product was originally intended, or where the model’s serial number
has been removed, altered or defaced.

Who is covered: Original purchaser so long as they reside in the United States
and can provide proof of the original date of purchase (e.g., store receipt) from
an authorized DAT retailer.

OUTSIDE THE UNITED STATES: Customers outside the United States should
contact their local sales office to obtain information on prices, exchange unit
availability, instructions, service and warranty/non-warranty repairs.

Repair or replacement under this warranty is the exclusive remedy of the
consumer. DAT shall not be liable for any incidental or consequential damages
for breach of any expressed or implied warranty on this product. Except to the
extent prohibited by applicable law, any implied warranty of merchantability or
fitness for a particular purpose on this product is limited in duration to the
duration of this warranty. Some states do not allow the exclusion or limitation
of incidental or consequential damages, or allow limitations on how long an
implied warranty lasts, so the above limitations or exclusions may not apply to
you. This warranty gives you specific legal rights and you may also have other
rights that may vary from state to state.

HOW TO OBTAIN WARRANTY SERVICE

In the event a DAT product should require servicing, you should
(a) visit an authorized DAT retailer or
(b) call the DAT Service Dept. at 1-866-328-2834.
To be eligible for warranty service within a three (3) year period, the
accompanying receipt of original purchase from an authorized DAT
retailer must specifically note that dealer installation was provided.

A retrun authorization (RA) number must be obtained before any
product can be returned to Diamond Audio. Product returned for
repair/service must be properly packaged and clearly marked with the
Return Authorization (RA) number issued by DAT. If the RA number is
not clearly marked on the package or the packaging is not adequate
to protect the contents, the product may be refused upon delivery.
DAT does not assume responsibility for lost or misdirected product.

INSTALLATION

On the facing page you will find Thiele/Small data and suggested enclosure
volumes for Diamond CM3 Subwoofers. The enclosures specified here are offered
as a suggestion only. Since enclosure design is as important to sound quality as the

speaker itself, it is recommended that your Authorized Diamond Retailer assist you
in designing and building an enclosure to suit your vehicle.
For more information on selecting the best subwoofer enclosure, visit the FAQ page
of our website, www.diamondaudio.com

Diamond's CM3 Series subwoofers are primarily designed for use with small sealed

enclosures. Good results have also been achieved in vented and bandpass enclosures.
HIGH PASS ("SUBSONIC") FILTERS MUST BE USED WITH NON-SEALED APPLICATIONS
TO PREVENT OVER-EXCURSION AT FREQUENCIES BELOW PORT TUNING.

The enclosure volumes shown opposite are NET INTERNAL VOLUMES. Driver, vent
and brace displacement must be taken into account when designing your enclosure.
