    What to do if my MTX Amplifier is blowing fuses?
    • J
      Jessica HollowayJul 27, 2025
      If your MTX Amplifier is blowing fuses, it could be due to excessive output levels. Try lowering the volume. Alternatively, the amplifier may be defective, in which case it should be returned for service.

    Why is there power LED on but no output from my MTX JH15001 Amplifier?
    • K
      Katherine RayAug 1, 2025
      If the power LED is on but there's no output from your MTX Amplifier, several factors could be responsible. The volume on the source unit might be off, so increase it. Check if the speaker connections are properly made and ensure the gain control on the amplifier is turned up. Signal processing units might be off, so apply power to them. Finally, all speakers might be blown, so replace them if necessary.

    Why is the output distorted on my MTX Amplifier?

      Isaiah GardnerAug 7, 2025
      If the output from your MTX Amplifier is distorted, it could be due to the head unit volume being set too high, so lower it. Alternatively, the amplifier gain might be set too high; in that case, lower the amplifier gain.

    How to fix reversed balance on MTX JH15001 Amplifier?
    • L
      Leah PattonAug 11, 2025
      If the balance is reversed on your MTX Amplifier, check if the speaker wires (left and right) are reversed and correct their orientation. Also, verify if the RCA inputs are reversed and, if so, reverse them.

    What to do if there is no LED indication on my MTX JH15001 Amplifier?
    • S
      Shelby JohnsonAug 16, 2025
      If there is no LED indication on your MTX Amplifier, it could be due to several reasons. There might be no +12V at the remote connection or the power connection; in either case, supply +12V to the terminal. An insufficient ground connection could also be the cause, so verify the ground connection. Lastly, a blown power fuse could be the issue, so replace the fuse.

    Why is the bass weak on my MTX JH15001 Amplifier?
    • D
      david31Aug 21, 2025
      If the bass is weak on your MTX Amplifier, it could be because the speakers are wired out of phase; wire them with the correct phase. Another reason might be not using MTX subwoofers, so consider purchasing MTX subwoofers.
