What to do if my Dual Amplifier unit blows fuse(s)?
- M
  matthewadkinsAug 14, 2025
  If your Dual Amplifier keeps blowing fuses, it could be due to several reasons. First, ensure you are using fuses with the correct rating. An incorrect rating can cause them to blow prematurely. Second, check for any pinched +12V wire touching the chassis ground, as this can cause a short. Finally, defective or damaged speakers can also cause fuses to blow, so inspect and replace them if necessary.

Why is my Dual Amplifier LED red (protect mode)?
- P
  Pamela HaysAug 17, 2025
  If the LED on your Dual Amplifier is red, indicating protect mode, there are several potential causes. First, check if any speaker wires are touching each other or the chassis ground and insulate any bare wires. Second, your speakers might be defective or internally shorted, so inspect and replace them if necessary. Finally, ensure the speaker load is not less than 2 ohms in stereo mode or less than 4 ohms when bridged, and adjust the speaker load accordingly.

How to fix engine noise in my Dual Amplifier?
- J
  Jessica RodriguezAug 21, 2025
  To resolve engine noise in your Dual Amplifier, start by ensuring the amplifier is grounded to a clean, bare metal surface for a good ground connection. Also, try re-routing the RCA cables away from existing high current wiring to avoid signal ground loops or radio frequency interference (RFI).

What to do if my Dual Amplifier has power but no sound?
- M
  Mark GomezAug 26, 2025
  If your Dual Amplifier has power (blue LED) but no sound, check the following: 1. Ensure the speaker wires are properly connected at the speakers. 2. Increase the volume level at the head unit, as the volume might be turned all the way down. 3. Check for any speaker wires touching each other or the chassis ground, and insulate them. 4. Inspect the speakers for any defects or damage, and replace if necessary. 5. Verify that the input signal is properly connected, checking both high and low level inputs.

How to troubleshoot Dual Amplifier not turning on?
- J
  John MillerSep 5, 2025
  If your Dual Amplifier won't turn on (no power LED indicator), check the following: * Ensure the +12V wire is connected and has the correct voltage (11~16VDC). * Verify the REM wire is connected and has the correct voltage. * Confirm the GND wire is properly connected to ground. * Check and replace any blown fuses.
