My amp just stopped working one day almost new dont known why

DID YOU CHECK YOUR FUSES? Is there anything lighting up on it to see if it is in fact turning on? If it's lighting up and there is no protection lights lit up then check your speakers to make sure you didn't burn them up. If there is a protect LED lit then unhook your speakers and see if it stays lit or not. If it stays lit then check to make sure you're getting enough voltage at the amp connection, minimum of 11.0 volts is required just to get it to turn on. If it has under voltage and over voltage protection LEDs see if they're lit. If you do all of these things and are getting enogh voltage, your speakers are not burnt, your protection LEDs are lit no matter what then you need warranty repair that amp. If your speaker wires are shorted it will make your amp shut down also, but since you were using it for a day or so my bet is that you burnt up one of your speaker voice coils and it's internally shorted and that will cause your amp to shut down in protect mode. Otherwise you probably internally fried your amp by too low of voltage or not enough current (amperage) due to not large enough conductor (too small gauge wire) should be minimum of 8 Ga. for each amp, 2 amps will require 4 Ga, 3 or more will need 2 Ga, or 0 Ga. wiring to keep the voltage and current flow high enough to keep from damaging the amps. Good Luck!

Protection lihgt on

Was the "fault" light on when she popped? There is no reset I'm aware of...they have a bad circuit if overloaded...meaning run below 13.7V for more than a minute or two. Can only be fixed at an electronics repair shop...sorry

Amp Power light will not go on. Protection light is lit- Thump sound in speakers

It probably has shorted output transistors. To eliminate other possible causes, read through the following page.

My amp is on but the protection light stay's on!!

Disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If the protect light remains on, the amp likely has blown output transistors.
