Deaf Bonce amplifiers are high-quality and technically perfect products. The problems often arise due to improper use, faulty
connection of components or lack of power supply of the on-board network.
1) The amplifier does not turn on.
Problem solution: Check all the contacts and the presence of 9-15 V at the amplifier terminals. Check whether the control input
of the amplifier "REM IN" receives the positive potential of +12 V.
Check the amplifier for overheating. Check the load impedance.
Problem solution: Check the connection of the amplifier, the integrity of the interconnecting cable, HU, the speakers or the
subwoofer.
4) The amplifier is turned on, but there is no sound from the speakers or subwoofer.
2) Power turns on, but goes into protection (security indicator lights up)
3) The amplifier turns on but at a high volume it goes in to protection. Problem solution: The amplifier may lack power. Make
sure that the rated current of the alternator and the battery capacity is enough to power this amplifier.
Problem solution: Check if there is a short circuit (fault) on the amplifier output which is connected to the speakers or
subwoofers. Make sure that commutation of the voice coils of the subwoofer is correct. The rated impedance of the voice coils
should not be lower than the permissible rated load impedance of the amplifier. Check the supply voltage of the amplifier. It must
be within the range of 9-15 V.
