If you're experiencing sound in only one channel of your Ground Zero Amplifier, begin by inspecting the speaker leads for any short circuits or open connections. Next, check the audio leads by reversing the left and right RCA inputs to see if the issue originates before the amplifier.
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.
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.
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.
How to fix no sound on one channel of Ground Zero IRIDIUM?
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 does my Ground Zero Amplifier turn off at medium or high volume?
Your Ground Zero Amplifier might be turning off at medium or high volume because the load impedance of each speaker isn't correct. Verify that each speaker's load impedance matches the technical specifications of the amplifier.
Why does my Ground Zero Amplifier Status LED turn on red?
The Status LED on your Ground Zero Amplifier turns red because the temperature protection circuit is active, or the speaker wires are shorted, or the speaker is damaged. To resolve this, decrease the head unit's volume or wait for the amplifier to cool down. Also, check the speaker and wires, and insulate if necessary.
What to do if Ground Zero Amplifier does not turn on?
If your Ground Zero Amplifier isn't turning on, check the power wire and connections to ensure they are properly connected. Also, verify the remote wire connection to the head unit is powered, especially in RCA input mode.
How to fix a Ground Zero IRIDIUM that's not switching on?
If your amplifier isn't turning on, the issue might be a lack of power to the amplifier. Check the power wire and its connections. Also, ensure that the remote wire is receiving power when the receiver is on; inspect the connections to the radio.
Why is there no sound coming from my Ground Zero IRIDIUM Amplifier?
If the POWER LED is not illuminated, check the fuses in the amplifier, ensure the remote lead is connected, verify the signal leads, recheck the control settings, and confirm the tuner/deck volume level. If the diagnostic LED is illuminated, inspect for a speaker short or amplifier overheating.
