If the status LED on your Ground Zero Amplifier turns 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 wait for the amplifier to cool down. Also, check the speaker wires and speakers for shorts or damage, and insulate if necessary.
Why does my Ground Zero GZTA 2255X-B have no audible sound?
If your Ground Zero Amplifier produces no audible sound, several factors could be at play. First, check 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 PRO LED is red, inspect for a speaker short or amplifier overheating.
What to do if Ground Zero GZTA 2255X-B device does not turn on?
If your Ground Zero Amplifier isn't turning on, the issue might stem from its power supply or the remote wire. Check the power wire and its connections. Also, verify the remote wire connection to the head unit, especially if you're using RCA input mode.
Why does my Ground Zero GZTA 2255X-B turn off at medium or high volume?
If your Ground Zero Amplifier shuts down at medium or high volume, the load impedance of the speakers might be the problem. Verify that each speaker's load impedance matches the amplifier's technical specifications.
How to fix no sound on one channel of Ground Zero Amplifier?
If you're experiencing sound on only one channel of your Ground Zero Amplifier, there might be an issue with the speaker wiring or input signal. Check the speaker wiring for short circuits or open connections. To test the input signal, reverse the left and right RCA inputs to see if the problem switches channels.
