O

Thank you for purchasing an Infinity Beta Ten.dvc
10" Dual Voice-Coil Subwoofer. You’ve selected a
premium product that offers superior performance
and advanced materials, resulting from over 25
years of loudspeaker design. This Infinity product is
made with our ongoing dedication to create the best
consumer audio products possible. As a result, you
can expect your new Beta Subwoofer to provide you
with many years of listening enjoyment.

Refer to Subwoofer Enclosure Trade-Offs (on the
inside pages) for help in selecting an enclosure type
and alignment. Also, review the wiring diagrams (on
the back page) on how to connect the subwoofer for
2-ohm, 8-ohm, and summed-mono applications.

Each Infinity Beta Ten.dvc 10" Dual Voice-Coil
Subwoofer is covered by our limited parts and labor
warranty (see the enclosed warranty card). Keep
your original dated bill of sale in case warranty ser­vice is required.

IMPORTANT: Installation of automotive stereo
components can require extensive experience in
dealing with a variety of electrical, and
mechanical procedures, including subwoofer
box building. Although these instructions
explain how to install a Beta Subwoofer in a
general sense, they do not show the exact instal­lation methods for your particular vehicle. If
you do not have the experience, do not attempt
the installation yourself; instead ask your
Authorized Infinity Car Audio Dealer about
professional installation options.

PRECAUTIONS

• Always wear protective eyewear when using tools.

• Turn off all audio systems and other electrical
devices before starting the installation.

• Disconnect the (–) negative lead from your vehi­cle’s battery.

• Locate and note all fuel lines, hydraulic brake
lines, and electrical wiring. Use extreme caution
when cutting or drilling in and around these areas.

• Check clearances on both sides of a planned
mounting surface before drilling any holes or
installing any screws.
