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" receives the positive potential of 12 V.
2) Power turns on, but goes into protection (security indicator lights up)
Problem solution: Check if there is a short circuit (fault) on the amplifier output which is connected to the 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.
3) The amplifier turns on but at a high volume it goes 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.
Check the amplifier for overheating. Check the load impedance.
4) The amplifier is turned on, but there is no sound from the subwoofer.
Problem solution: Check the connection of the amplifier, the integrity of the interconnecting cable, HU or the subwoofer.
