I installed a MTX Thunder 3401 with a PA sub.

You are def overheating, If the ohms rating of the subwoofer is too low it will cause this same thermal over heat. If you have 2ohms in sub and a 4 ohms stable amp, you will overheat. Check the ohms rating of the sub to make sure this is not the problem

THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF

If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

Fuses

Check the ohm measurement of the speakers make sure they are about the rated ohms.Check them UNHOOKED from the amp. (Useually 4 ohms.)

Try different subs.

My amp

Kind of a vague problem description, can you be a little bit more specific. What problems you are experiencing, how many speakers/subs were you powering with it, does it show that it has power, did you check the fuses?

I have a mtx tunder series 942 when you hook it up the red light comes on I have the best wire and have checked everything the amp is old school it does have a fuse on it I have one on my power line pls help!!!!!

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
