OCATION
Choose a mounting location that doesn’t interfere
with cargo, fold-down rear seats or the trunk lid.
The best location is usually a corner of the trunk
or cargo area, as shown in Figures 1 and 2.
These locations, in addition to being out of the
way, will provide the best sonic reproduction in
the 60Hz to 100Hz range because the woofer out-
put will be “corner loaded” against the vehicle’s
walls. In any case, BassLink II must not interfere
with the safe operation of the vehicle.

THANK YOU
for choosing the Infinity

powered subwoofer. BassLink II has been designed
to provide the kind of high-performance low-
frequency reproduction that used to require big,
clumsy enclosures, large amplifiers and complex
installation. To ensure maximum performance,
we strongly recommend that installation be
entrusted to a qualified professional. Although
these instructions explain how to install the
BassLink II in a general sense, they do not show
the specific installation methods for your particular
vehicle. If you feel you do not have the necessary
tools or experience, do not attempt the installation
yourself; rather, ask your authorized Infinity car
audio dealer about professional installation options.
Remember to keep this manual and your sales
receipt in a safe place for future reference.
HEARING WARNING!
Playing loud music in a vehicle can permanently
damage your hearing, as well as hinder your ability
to hear traffic. We recommend using low volume
levels while driving. Infinity accepts no liability for
hearing loss, bodily injury or property damage
resulting from the use or misuse of this product.
YOUR CAR AND BASS REPRODUCTION
Depending on the interior volume of your vehicle
and the dimensions of the passenger compartment
and cargo area, reproduced frequencies below
80Hz may be boosted by nearly 12dB per octave
as frequency decreases.This effect, known as the
vehicle’s “transfer function” or “cabin gain,” plays
an important part in shaping the overall in-car
response of the BassLink II.
BassLink II is designed to work with your vehicle’s
other speakers to reproduce frequencies below
100Hz. Moreover, depending on orientation and
mounting location, BassLink II may be “in phase”
or “out of phase” with those speakers. The resulting
conditions, known as constructive and destructive
interference, also play a role in shaping the total
frequency response of your system. Fortunately,
BassLink II has controls to optimize both of these
conditions, and their adjustment is explained later
in the manual.
CAUTION:
Make sure mounting screws will not
puncture wiring harnesses, brake or fuel lines, or
the vehicle’s fuel tank. Some or all of these may
be located behind or under the mounting surface.
VERTICAL MOUNTING
Position BassLink II so that the heatsink is facing
down and the bottom of the unit is up. Align the
mounting feet as shown in Figure 3. Secure the
feet using the supplied machine screws.
Place BassLink II (with its feet) so the controls
are easy to adjust. Securely mount BassLink II to
the mounting surface with the four enclosed self-
tapping screws.

HORIZONTAL MOUNTING
Position BassLink II so that the controls are facing
down and the back of the unit is up. Align the
mounting feet as shown in Figure 4. Secure the
feet using the supplied machine screws.
Securely mount BassLink II to the mounting
surface using the four enclosed self-tapping
screws.
