    What to do if my Audiovox Phase Linear UPA224 does not turn on?
    • J
      James ThompsonJul 30, 2025
      If your Audiovox Amplifier isn't turning on, there are several potential causes. First, check the fuse(s) because there might be no power to the +12V terminal. Also, check the head unit fuse(s) and wiring, as there might be no power to the REM terminal. Replace the fuse and identify the cause of failure if the main fuse at the battery or the fuse at the amplifier is blown. Lastly, reground the main power ground to a bare metal chassis in case of a faulty ground.

    Why is there engine noise or alternator whine in my Audiovox Phase Linear UPA224?

      Bryan LambAug 6, 2025
      Engine noise or alternator whine in your Audiovox Amplifier can stem from several issues. It could be due to ground loop(s), so using good quality shielded RCA cables is advisable. A faulty ground at the amp or head unit can also cause this, so reground both to a clean, bare metal chassis. Inductive coupling might be the problem, requiring you to reroute RCA and/or speaker wires away from factory harnesses. Lastly, readjust the input level, as the input level on the amp might be set too high.

      If your Audiovox Amplifier is blowing fuse(s), it could be due to power wires connected backwards; reconnect them properly. Alternatively, there might be an internal problem with the amp, in which case you should take the unit for service.

    Why is the volume control too sensitive on my Audiovox Amplifier?
    • C
      Corey JacksonAug 21, 2025
      If the volume control on your Audiovox Amplifier is too sensitive, it's likely that the input level control is adjusted too high. Readjust the input level to decrease the sensitivity.
