Amplifier will not power up:
• Check for good ground connections. Ensure that the ground cable is
connected directly to bare metal and not a painted surface.
• Check that there is audio being output by the source (headunit)
• Using a multimeter ensure that the Battery voltage is at least 12v DC and
below 16v DC.
• Check all fuses.
• Check that the protection light is not illuminated, if it is illuminated try
turning the amplifier off for a short period of time and then turn back on.
Blown Fuse:
• Check both positive and ground cables for shorts.
• Check that the positive wire is connected to the +12V terminal of the
amplifier
• Check that the negative wire is connected to the GND terminal of the
amplifier
• Check that the correct value fuse is fitted: 25 amps
Protection LED is illuminated:
• Check for shorts on all cables
• The amplifier is designed to shut down automatically when the temperature
reaches 80°C, if the amplifier heatsink is very hot this may be the reason for
the amplifier shutting down.
• Remove the signal cables and try to restart the amplifier, if the amplifier will
not restart then it is possible that the amplifier or subwoofer has been
damaged. This damage may have been as a result of abuse or failure to
follow the advice in this manual.
Distorted sound:
• Reduce the gain until the sound is no longer distorted .
• Ensure that excessive bass boost is not applied.
• Check the equaliser settings of the head unit and ensure that there is no
excessive bass boost applied.
