I am having an issue with my Sundown SAEv4-600.1D slipping into protect immediately when my car turns on. it powers a Punch p3 12" fosgate. it will do one of these things, turn on and actually turn on for a second then power off, not turn on and thump twice on the sub, turn the power light on the bass knob on but its not actually on at all, or sometimes and very rarely it will work for like 5 minutes then power off. I have tried everything, I have put an entire new amp in, I have replaced every wire going to the amp and I mean every wire, changed dsp outputs to rule out dsp fault, disconnected sub and still had issues, changed ground points, literally everything. I have my big 3 done, I have a 250a high output alternator, and an XS Power D3400R, so power and voltage isn't an issue. Every other amp in my system works without an issue. I have troubleshot every thing I can think of, I have even disconnected every wire other than power, ground, and remote turn on and the amp still slips into protect. Im at a loss for what it could be, if anyone has any ideas I would greatly appreciate it.
