How to fix a ticking or whine that changes with engine RPM in my Hifonics Brutus BXI 1608D?
- T
  Thomas SanchezAug 13, 2025
  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?
- C
  Cathy AndersonAug 17, 2025
  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.

Why is my Hifonics Brutus BXI 1608D Amplifier heatsink overheating?
- A
  Alexandria GatesAug 25, 2025
  If your Hifonics Amplifier's heatsink is overheating, it could be due to inadequate cooling. Try relocating or remounting the amplifier to allow for better airflow over the fins. Another cause could be driving high power levels into low impedances. Reduce the volume or ensure that you are not loading the amplifier with less than the recommended loudspeaker impedance.

What to do if my Hifonics Brutus BXI 1608D Amplifier system does not turn on?
- D
  Dr. Daniel ScottAug 28, 2025
  If your Hifonics Amplifier system does not turn on, begin by checking all fuses and connections. Then, measure the +12 volt and remote turn-on voltages at the amplifier terminals. If these voltages are low or nonexistent, measure the voltage at the fuse holders, distribution blocks, and the head unit's +12 volt and remote leads to identify the source of the problem.

Why does my Hifonics Brutus BXI 1608D Amplifier keep blowing fuses?
- J
  John LunaSep 1, 2025
  If your Hifonics Amplifier is blowing fuses, check that you are not using loudspeaker impedances below the recommended minimums. A short on the main +12 volt cable from the battery to the vehicle chassis can also cause the main fuse to blow. If an amplifier fuse blows continually with only the +12 volt, ground, and remote leads connected, the amplifier may be faulty.

How to troubleshoot low output power on a Hifonics Brutus BXI 1608D?
- C
  Cynthia FuentesSep 4, 2025
  If you're experiencing low output power from your Hifonics Amplifier, first verify that the level controls have been set up correctly. Also, ensure that the battery voltage, measured at the amplifier's +12 volt and ground terminals, is 11 volts or higher. Finally, check all +12 volt and ground connections to ensure they are secure.

Why is my Hifonics Amplifier producing hiss or white noise?
- M
  Mary FrazierSep 8, 2025
  High levels of white noise (hiss) from your Hifonics Amplifier usually occur when the amplifier level controls are turned up too high. Readjust them according to the procedures in section 'Setting up systems after installation for best performance'. If that doesn't solve the issue, unplug the amplifier input RCA cables. If the hiss level reduces, the source unit is likely the cause.
