Infinity Bass Link User Manual

Thank you

for choosing the Infinity BassLink.
BassLink 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 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.

WARNING: Playing loud music in an automobile
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/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.

BassLink is designed to reproduce frequencies
below about 100Hz, but there may be other
speakers in your vehicle that reproduce some
of those same frequencies. It is important that
all the speakers work together to reproduce
frequencies they share. Depending on the
orientation of the BassLink and the distance
from it to the other speakers, the BassLink and
the other speakers may be “in-phase” or
“out-of-phase”. The resulting conditions, known
as constructive and destructive interference,
also play a role in shaping the frequency
response of your system.

Fortunately, BassLink has controls that may be
adjusted to optimize both of these conditions.
Successful installation will include “tuning”
those adjustments; this process is detailed
in a subsequent section of this manual.

INSTALLATION

CHOOSING A MOUNTING LOCATION

Choose a location that doesn’t interfere with
the loading or unloading of cargo, fold-down
rear seats, or opening or closing of the trunk lid.
The best location is likely to be the front or rear
corner of the trunk or luggage compartment.
These locations, in addition to being out of the
way, will provide the best sonic reproduction in
the 60Hz – 100Hz range because the output of the
woofer will be “corner loaded” against the walls
of the vehicle. In any case, the BassLink must not
interfere with the safe operation of the vehicle.

Once you’ve chosen a mounting location and
made the necessary electrical connections,
you’re ready to mount BassLink securely to the
mounting surface (most likely the floor of the
luggage compartment). 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.

MOUNTING BASSLINK

Note: A nut has been molded into one of the
flanges of each of the mounting feet to facilitate
the attachment of the feet to BassLink. Orient
the feet so that the captive nut is opposite the
control panel. The attachment screws may then
be passed through the front or top and attached
to the nut in the back or bottom. See Figures 1
and 2 for details.

Vertical Mounting: Slide the two vertical
mounting feet over the bottom of BassLink until
they snap into the indentations molded into the
bottom and sides of BassLink. The three side­mounted knobs (controls) should face the interior
of the trunk or luggage compartment for easy
adjustment. Insert the bolt provided through the
hole opposite the mounting foot and tighten it
with a screwdriver. Securely mount BassLink to
the mounting surface with tapping screws. You
will use two bolts to mount BassLink vertically.

Figure 1.Vertical mounting of BassLink.

Horizontal Mounting: Slide the four horizontal

mounting feet over the sides of BassLink until
they snap into the indentations molded into
the sides and bottom of BassLink. The three
side-mounted knobs (controls) should be
facing up to allow adjustment after the unit is
mounted. Insert the bolt provided through the
hole opposite the mounting foot and tighten it
with a screwdriver. Securely mount BassLink to
the mounting surface with tapping screws. You
will use four bolts to mount BassLink horizontally.
