Introduction
With the Planet Audio BB2 Class D
amplifier series, we are introducing
two new CLASS D amplifiers, both
designed in the USA.
These Big Bang models feature
variable low pass and subsonic filters
and a variable input gain control. These
models also incorporate a phase
selector switch to help compensate
for time delays in subwoofer
applications.
For further flexibility in the use of a
subwoofer, a variable 0-+18dB Bass
Boost control has been included.You
can control the subwoofer level with
the remote level control module.
Planet Audio understands that
amplifiers are placed in many different
kinds of installations, so we have also
included an input sensitivity control to
help you integrate the amp into your
system regardless of the nature of your
input source.
A special feature on this Class D amp
is DataLink circuitry, which allows you
to “strap” (bridge) together two
identical BB2 Class D amp models for
an astounding total maximum output
power of between 3800 and an
astounding 6000 watts, depending on
the model selected.

Installation precautions
Before you drill or cut any holes,
investigate your car's layout very
carefully. Take special care when you
work near the gas tank, fuel lines,
hydraulic lines and electrical wiring.
Never operate the amplifier when it is
unmounted. Attach all audio system
components securely to prevent
damage, especially in an accident.
Before making or breaking power
connections in your system, disconnect
the vehicle battery. Confirm that your
head unit or other equipment is turned
off while connecting the input jacks and
speaker terminals.
If you need to replace the power fuse,
replace it only with a fuse identical to
that supplied with the amplifier. Using
a fuse of a different type or rating may
result in damage to your audio system
or your amplifier which is not covered
by the manufacturer's warranty.
Mounting the amplifier
1. Find a suitable location in the vehicle
in which to mount the amplifier.
2. Make sure there is sufficient air
circulation around the intended
mounting location.
General precautions
Before installing and using your new
Planet Audio amplifier, please become familiar with all the information
contained in this manual.
Please keep this manual in a safe
place for future reference.
• Do not open or attempt to repair this
unit yourself. Dangerous high voltages
are present which may result in electric
shock. Refer any repairs to a qualified
service technician.
• To avoid risk of electronic shock or
damage to the amplifier, do not permit
any of this equipment to become damp
or wet from water or drinks. If this does
occur, immediately unplug the power
wires and send the amplifier to your
local dealer or service center as soon
as possible.
• If there is smoke or any peculiar odor
present during use or if there is damage
to any of the component enclosures,
immediately unplug the power cord
and send the amplifier to your local
dealer or service center as soon as
possible .
What is included?
When first unpacking your new
amplifier, please check first that the
package contains all of the items
below. If something is missing, contact
the store where you purchased the
amplifier.
• Class D amplifier
• Remote subwoofer level control
• Remote subwoofer control cable
• DataLink cable (for bridging two
identical BB2 Class D amplifiers
together)
• Four (4) mounting screws
BB2400.1 • BB1400.1 Amplifier User’s Manual - page 4
3. Mark the location for the mounting
hole screws by positioning the amplifier
where you wish to install it. Use a scribe
or mounting screw, inserted through
each of the amp's mounting holes, to
mark the mounting surface. If the
mounting surface is carpeted, measure
the hole centers and mark with a felt
tip pen.
4. Drill pilot holes in the mounting
surface for the mounting screws. Place
the amplifier in position, and attach
the amplifier to the mounting surface
securely using screws.
Before doing any wiring, look through
this manual and identify the diagrams
to follow for power, input and speaker
connections for your particular
installation. Be sure you understand
all the connections before you proceed.
1. Connect the amplifier’s power
ground terminal to the closest point
on the chassis of the car. Keep this
ground wire to less than 39" (100 cm)
in length. Use 4 gauge (or heavier)
wire.
2. Connect the remote terminal to the
remote output of the head unit using
16 gauge (or heavier) wire.
3. Connect an empty fuse holder within
18" (45 cm) of the car battery, and run
4 gauge (or heavier) cable from this
fuse to the amplifier location.
The purpose of placing a fuse in this
location is to protect your vehicle’s
battery in the event that this wire
accidentally touches the chassis
ground on its run to the amplifier.
Connecting the amplifier
4. Check that the fuse holder is empty.
Then connect the fuse holder to the
"BATT+" connection on the amplifier.
5. If multiple amplifiers are being used
in your system, either:
• Run a separate pair of cables from
the battery and a chassis ground point
to each amplifier. Each (+) cable must
have its own inline fuse.
-or-
• Run a #0 cable from the fuse holder
at the battery to a distribution block
at or near the amplifier's location. Then
run separate cables from the amplifier
to this distribution block and to
independent chassis ground points.
6. Connect all line inputs and outputs
(if used) using high-quality cables.
Connect all speakers, following the
diagrams in this manual. Be sure to
observe proper polarity to avoid audio
phase problems.
7. Insert fuse(s) into the battery fuse
holder(s).
8. Recheck all connections before
powering up the amplifier.
9. Set all level controls to minimum
position, and set all crossover
controls/switches to the desired
frequency points.
10. Power up the head unit and the
amplifier. Then set the volume control
on the head unit to about 3/4 volume,
and adjust the amplifier’s input level
control(s) to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain
best results.
