Precisely, how and where did you add thermistors?
If you disconnect the new thermistors, does that make a difference?

I put the Thermistors in TH1,TH2 locations as the schematic shows I just soldered them in place like the originals were .
Only reason I replaced them is because the old ones had broken legs .
I didn’t try powering the amp up again since the thermistors are still soldered in the board .
I will remove them and try powering the amp up again

I put the 2 boards back together amp powers up for a second now and goes straight into protection . Relays kick on the off
I removed the audio driverboard so I don’t blow the outputs . I removed the thermistors and the amp will power up for a second then go into protection
Do you see any DC Voltage measured from gate to source on any output transistor from the time that remote is applied to the time it goes into protect?
That would seem to indicate that you have some sort of leakage.
Is all of the flux cleaned off of the board?

If you resolder all of the driver board pads, does the solder for every pad readily flow through the via to the pad on the other side of the board?
If you connect a sub to the output of the amp, does it pop or move from its center position as the amp tries to power up?
Does the amp go into protect?
Of course, shut the amp down immediately if the amp drives DC to the sub.

I noticed now the amp will power up go into protection power up and go into protection. It just keeps repeating the cycle over and over .
The amp goes into protection still with the sub hooked up .
And the rest sub pops when trying to power the amp up over and over as the amp cycles in and out of protection

Are you 100% sure that you don't have a bad output FET?
If you connect a dummy load (or a rugged sub) to the amp and let it cycle, which of the outputs heats up?
Is the amp making full rail voltage or is it not much over the 20v as it tries to power up?

I checked all of the outputs in the amp and they all test fine . I guess I will have to pull them and tear them out of the board
