    Why does my Hifonics BXiPRO1.5 Automobile Accessories have low output power?
    • S
      Sarah MaxwellJul 30, 2025
      Several factors can cause low output power. First, verify that the level controls are properly set. Next, ensure the battery voltage at the amplifier and crossover terminals is at least 11 volts. Finally, inspect all +12 volt and ground connections to make sure that they are well connected.

      Julie BallAug 6, 2025
      A constant whine usually stems from instability causing oscillations. Begin by inspecting all connections, paying special attention to ensure good grounds. Also, check that no speaker leads are shorting against exposed metal on the vehicle chassis.

    How to stop Hifonics BXiPRO1.5 Automobile Accessories ticking or whine that changes with engine RPM?

      Mikayla GibsonAug 13, 2025
      Ticking or whine that changes with engine RPM can happen when RCA cables pick up radiation near the fuel pump or distributor. Ensure the head unit ground connects directly to the vehicle chassis, avoiding factory wiring. If that doesn't help, try supplying the head unit with a clean +12 volt supply directly from the battery +, instead of using the in-dash wiring/fusebox.

    Why does my Hifonics Automobile Accessories have hiss or white noise?
    • W
      Wendy BeckerAug 22, 2025
      High levels of white noise often occur when level controls are set too high. Try reducing the levels until the noise disappears. If the issue persists, unplug the crossover input RCAs; if the hiss diminishes, the source unit is likely the cause.
