How to fix distorted sound from Aunex AC2000.4D?
If you're experiencing distorted sound from your Aunex Amplifier, try readjusting your amplifier's gain to a lower setting. You can also try readjusting your source unit volume or the Boost EQ.
What to do if Aunex Amplifier powers up but there is no sound?
If your Aunex Amplifier powers up but produces no sound, you can check your RCA connectors to see if there is a signal using a Digital Multi-Meter to measure AC voltage. Also, check your speakers for any shorts.
How to stop hissing noise from Aunex AC2000.4D Amplifier?
If you hear hissing or engine noise from the speakers connected to your Aunex Amplifier, consider these steps: * Readjust your amplifier's gains to a lower setting. * Readjust your source unit volume. * Ensure your RCAs and speaker wires are routed away from your power and ground connections. * Remove existing ground wires for all electrical components and reground them to a different, clean, rust-free location. * Add a secondary ground cable from the negative battery terminal to the chassis metal or engine block of the vehicle. * Check your RCA cables or speaker input for any damage.
What to do if Aunex AC2000.4D Amplifier does not work and no LEDs are on?
If your Aunex Amplifier isn't working and no LEDs are lit, check if the Power, Remote, and Ground are properly connected to the amplifier. Verify the Power and Remote Turn-on lead have the correct +12 Voltage (acceptable range: 12-16 Volts DC). Inspect the inline fuse and replace it if needed.
Why is the logo LED red on my Aunex AC2000.4D?
If the Logo Status LED on your Aunex Amplifier is red, indicating the protection circuit is active, the amplifier might be in thermal protection due to overheating. Check the inline fuse and replace it if necessary. Also, check the voltage at the amplifier power input terminals.
