How to fix a ticking or whine that changes with engine RPM in my Hifonics Brutus BXI 1608D?

  If you hear a ticking or whine that changes with the engine RPM in your Hifonics Amplifier, relocate the RCA cables, as they may be picking up radiation from a fuel pump or distributor. Ensure that the head unit ground is connected directly to the vehicle chassis and is not using factory wiring for ground. Also, try supplying the head unit with a clean +12 volt supply directly from the battery +, instead of using a supply from the in-dash wiring/fusebox.

How to eliminate a constant whine in my Hifonics Brutus BXI 1608D Amplifier?

  If you are experiencing a constant whine with your Hifonics Amplifier, it could be due to some kind of instability causing oscillations in the system. Check all connections, especially for good grounds. Make sure that no speaker leads are shorting to exposed metal on the vehicle chassis. Check the RCA cables to ensure they are in good condition, especially the shield connections.

What to do if my Hifonics Brutus BXI 1608D Amplifier goes into diagnostic mode?
- R
  Ryan KleinAug 21, 2025
  If your Hifonics Amplifier goes into diagnostic mode, it indicates an internal fault. If the diagnostic LED is lit, the amplifier has an internal problem. If the diagnostic LED is not lit, plug the RCA cables back in and reset the amplifier. If it then goes into diagnostic mode, the issue lies with the input, potentially due to faulty cables or the source unit. If the amplifier seems fine with the RCA cables plugged in, connect the speakers individually. If a speaker or its wiring is faulty, it will activate the diagnostic system.
