What does it mean when your amp is completely dead?
The Amp is Completely Dead If the amp is completely silent (no speaker hum or hiss at all) then the problem can be just about anywhere in the amp but you should suspect a bad tube, blown fuse or the power supply in that order. Try a new rectifier tube.
How can I tell if my amp is not working?
No matter what type of amp you have, something is supposed to change when you hit the on switch and turn up the volume. A lot of amps have power lights that activate when the amp is live. Also, listen for any noises the amp makes, since that could also help you determine the source of the problem.
What should I do if my amplifier powers up?
It’s important that you disconnect the speaker wires from the speaker terminals of the amplifier and disconnect all RCA cables from the RCA jacks of the amplifier. If the amp powers up after disconnecting the speaker and signal cables from it, try reconnecting the RCA cables.
What to do if your amp doesn’t go into protect?
If the amp goes into protect with the RCA cables plugged in, go to step 4. If it doesn’t go into protect, reconnect one pair of speaker wires at a time. If you’re using a mono amp and have only one pair of speaker wires, you’ll need to disconnect all but one speaker from the other end of the speaker wires.

Basic errors are most often the cause of sound system problems. A majority of these installation errors can be easily fixed by yourself. If you are experiencing any of the problems listed below, try some of the solutions that we offer. Check the remote turn on wire and power wires voltage. Check continuity on ground wire.
What happens when an amp goes into protection?
In MANY amplifiers, the power LED will be lit but the amplifier will be completely dead internally. This is especially true when the power supply has failed. There are a few amps (some JL Audio) that will go into protect and none of the indicators change.
