Infinity BASSLINK T User Manual

BassLink™T

Thank you

to provide the kind of high-performance low-frequency reproduction that used to require
big, clumsy enclosures, large amplifiers and complicated 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 T 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.

MOUNTING BASSLINK T

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 T.

BassLink T is designed to work with your vehicle’s
other speakers to reproduce frequencies below
100Hz. Moreover, depending on orientation and
mounting location, BassLink T 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.

BassLink T includes controls to optimize both
of these conditions and their adjustment is
explained in sections “Controls & Functions”
and “Tuning Basslink T”.

Choose a mounting location that does not
interfere with the seats, seat mechanisms
or cargo.

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.

BassLink T has been designed for easy installation
in many vehicle applications. BassLink T should
be secured to a solid mounting surface using the
supplied mounting hardware. There are multiple
indentations along the mounting flange. These
allow for different screw locations, depending
on your vehicle. BassLink T should be secured
using a minimum of four screws along the
different edges. Please see Figures 4 and 6.

POWER CONNECTIONS

ROUTING THE WIRES

All signal and power wires should be routed
through the opening provided at the rear of the
connection panel. On the rear of Basslink T are
two channels extending from the opening — one
horizontal, and one vertical — that may be used for
routing those wires to the vehicle.

Depending on installation requirements, all, or
some, of the wires may be routed straight down
along the vertical channel to the floor and hidden
under the carpeting, and/or across the horizontal
channel toward the side and hidden behind the
vehicle’s trim panels.

Figure 5. Channels for wiring.

ADDITIONAL MOUNTING FEET

If your particular application inhibits the ability to
secure the lower portion of BassLink T, please use
the supplied mounting feet. They slide into the
channels on the bottom of the unit and snap in
place. This will give you the ability to secure
BassLink T to the floor of your vehicle.

Figure 6. BassLink T installation with optional feet.

Connect power to BassLink T, as shown in
Figure 7. Also observe these installation tips:

•

Use at least #10 AWG wire for the +BATT
(+12 Vdc) and GND (ground) connections. If
needed, use at least a #20 AWG wire for the
REM (remote) connection.

•

Route all power wires through a grommet in
the vehicle’s firewall. If a factory grommet is
unavailable, install one.

•

Connect a short GND wire from BassLink T
to the nearest bare metal surface. For a
good connection, scrape away paint from
the metal surface and use a screw with a
lock (star) washer.

•

Install a fuse holder with a 25 A fuse within
18" of the battery’s positive (+) terminal (see
Figure 7).

•

The REM connection requires +5 to +12 Vdc
signal to turn on BassLink T. Most head units
with preamp outputs provide this remote
voltage signal. For speaker-level applications,
a remote connection is preferred but not
required, since BassLink T’s Auto Turn-On
feature will sense voltage on the speaker
wires to automatically turn on BassLink T.

IMPORTANT: To enable BassLink T’s Auto
Turn-On feature, set the AUTO TURN-ON
switch to the AUTO position (see Figure 13
on page 7).
