    What to do if my MTX WET Amplifier is blowing fuses?
    • P

      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 Amplifier?
    • C
      Curtis JohnsonAug 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?

      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 WET?
    • C
      Connie ColeAug 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 WET?
    • J
      Jenna WangAug 15, 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 Amplifier?
    • L
      Lindsey JordanAug 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.

Summary

Control Functions

+12 V Power Connection

Connect +12V power cable to the battery's positive terminal via a fuse or circuit breaker.

Ground Connection

Connect the GND terminal to the battery's negative terminal using the shortest, thickest wire possible.

Gain Control Adjustment

Adjust amplifier sensitivity to match the source unit's signal voltage (5V to 200mV).

Installation and Mounting

Fuse;Circuit Breaker Installation

Install a fuse or circuit breaker within 18 inches of the battery for protection.

Grounding Procedure

Connect the amplifier's GND terminal to the battery's negative terminal with an equal gauge wire.

Final Checks and Power On

Verify all connections, then reconnect the battery and turn on the circuit breaker/fuse.
