If you're experiencing no sound on one channel of your Ground Zero Amplifier, check the speaker wiring for short circuits or open connections. Additionally, verify the input signal on each RCA lead by reversing the left and right RCA inputs to test the audio input signal.
Why is the status LED on my Ground Zero Amplifier red?
If the status LED on your Ground Zero Amplifier is red, it could be due to the temperature protection circuit being active or shorted/damaged speaker wires. Try decreasing the head unit's volume or waiting for the amplifier to cool down. Also, inspect the speaker wires and speakers for shorts or damage, and insulate if necessary.
Why my Ground Zero Amplifier does not turn on?
If your Ground Zero Amplifier isn't turning on, verify the power supply and connections. Also, if using RCA input mode, ensure the remote wire is properly connected to the head unit.
What to do if my Ground Zero IRIDIUM has no sound?
If there is no audible sound from your Ground Zero Amplifier, start by checking if the POW LED is green. If not, examine the amplifier's protection fuse(s), the remote wire connection (in RCA input mode), the +12 Volt power supply wire connection, and the ground wire connection. If the PROTECT LED is red, inspect for speaker shorts or amplifier overheating.
