  If the status LED on your Ground Zero Amplifier turns red, it indicates that the temperature protection circuit has been activated, or there may be a short in the speaker wires, or the speaker is damaged. To resolve this, either decrease the head unit's volume or wait for the amplifier to cool down. Also, inspect the speaker and wires for any damage and insulate if necessary.

  If your Ground Zero Amplifier isn't producing any audible sound, 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, check for a speaker short or amplifier overheating.
