BB2400.1 • BB1400.1 Amplifier User’s Manual - page 8
If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
Low-level (RCA) input wiring is preferred for best audio performance. Always use
a high-quality RCA cable for best audio performance.
Protection LED
comes on when
amplifier is
powered up.
Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving.
Remove speaker leads, and reset the amplifier. If the Protection LED still
comes on, then the amplifier is faulty and needs servicing.
High hiss in the
speakers.
Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then
plug in the component driving the amplifier and unplug its inputs. If the
hiss disappears at this point, go on until the faulty/noisy component is
found.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to set
the head unit as high as possible (without distortion) and the amp input
level as low as possible.
Squealing noise
from speakers.
Check for improperly grounded RCA interconnects.
Distorted sound.
Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
very hot.
Check that the minimum speaker impedance for the amp model is correct.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add and external cooling fan.
Engine noise
(static type)
This is usually caused by poor quality RCA cables,which can pick up
radiated noise. Use only the best quality cables, and route them away
from power cables.
Engine noise
(alternator
whine)
Check that speaker leads are not shorted to the vehicle chassis.
Check that the RCA grounds are not shorted to the vehicle chassis.
Check that the head unit is properly grounded.
The fuse ratings for these amps is
described on the Specifications page
of this manual. Although sufficient for
normal working conditions,
overloading the amp may result in
blown fuses. Please try to avoid
overloading the amp in this manner.
Your BB

Class D amplifier is
designed to run with a mini-
mum load of 1 Ohm.
Operating a BB

Class D am-
plifier with a speaker imped-
ance load below 1 Ohm may
result in poor sound quality
and damage to the amplifier
circuitry. Such damage is not
covered under the warranty
for this product.

• 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 .
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.
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.
