0.2v/div is useless for most all class D amps.
Look up the datasheet if you don't know the pin configuration of any component. For most small transistors with an A, B, C or D prefix, the pin configuration is ECB. Look up the datasheet to confirm the configuration.
Do you have any 1k resistors?

Previously, the duty cycle was near 50%. Now it's very low. The difference may be that the amp was having trouble starting when your scope was causing problems.
Did you mean 'on' as in the scope was powered up or 'on' as in having your probe connected to the amp?
Reduce the 12v supply voltage. Can you force the amp to full duty cycle before it shuts down?
Leave the supply providing the remote voltage at the same voltage as it is now.

On as in scope powered up
I’m not sure how I would do that
I have my 40amp power supply powering it right now at 13.5v.
I have a second supply which I had shown previously.
I can hook both of them up, supply remote with 13.5v with the lower power supply, and lower my 40a supply to 12v, is this what you mean?
I cannot use the original supply for power as it is 3a max and the amp will not power on with that

No, but it still goes into protect when any sort of signal is passed. Swapped RCA plate from parts amp and same result.
I am using my phone with an aux to RCA cable adapter as a tone generator. I have a spare headunit I can use to see if it still goes into protect, do you think that would cause any change?
