Question about MTX Car Audio & Video
I was having a similar issue. I checked every wire from the battery to stereo to amp, checked the ground, pulled the stereo to double check the wiring was all correct. Everything seemed good so I thought it had to be my battery not putting out enough power. Tested it and it was good. What it turned out to be was the connection from the power cord to the battery. It had a tiny bit of built up corrosion that was making the amp go into protect mode. Cleaned it up and hooked it back up and has been golden since.
The link attached is pretty straight up on what you need to check for different circumstances. I'm guessing it's a low voltage issue. Good luck

if your amplifier has the internal Kicker card dealie "little computer card on the side that you can change out crossover settings and such," Turn off the vehicle, remove this device and make sure the contacts on the card are clean and free from black soot (showing a spark). clean the contacts with a pencil eraser or something hard but soft... and put the little card back in place, start the car again and see if that helps, I used to lose one speaker every once in a while with the same amp. I ended up replacing the module with a different one from my dealer and it worked fine (still does and it's been in my car 6 years). Check that little module. if this doesnt work, while the car is running and the music is "playing" wiggle the card and see if it works sometimes and not others. Likely is the little module.

Try disconnecting everything but the power connections. If the protection light still comes on, then there's a problem in the amp. If it goes out, then there's a problem elsewhere. In that case, hook up one speaker cable at a time and power on. If the protection light comes on, then either that speaker is bad, or you've got too many speakers connected to that one amp output. Too many speakers connected together can cause an overload and trigger the protection circuitry, or worse, blow out something out.
Hope this helps, and please rate my advice.
Thank you, and good luck!!

There are a number of things that can cause it to act as you described. Have you pulled the covers off of it yet to see if you can see any problems?
If you do, disconnect power from it and don't touch ANYTHING on the board when ANY of the 3 LEDs (2 are not visible from the outside) are lit.

disconnect audio inputs and outputs and see if one of those are causing it , if it still does it with all audio inputs and outputs disconnected then there is a problem with the power amp
