Amp goes into and out of protect mode

[JR2011bu]

So the issue started the other day, I was driving down the free way and I had to get around a semi so I floored it. My volume was up at around 32, my RPM's flew up to about 6500 and boom my highs were out. I turned it down and they played fine but amp would go in and out of protect at volumes over 29.

What would you all suggest I check first my speakers don't sound blown but I will check on them tomorrow morning once I wake up. It's a kicker zx350.4 running a pair of infinnity kappa 692.2i I believe.

Would my car excreting high voltage cause the amp to go into protect?

But would it not have blown the fuse on the amp?

If it did why would my amp come back on and off, wouldn't it just stay off?

Please help me it might be a bit late for some but all advice is appreciated thanks.

I have 0 gauge wire running from front to a 2f cap then a + line going into a fused distribution block one to my sub amp, and one to the kicker. Both Amps and cap grounded separately.

your voltage wouldnt go up when you raise the engine speed at all. I would check the amps connections for any loose speaker wires. I had it before where i punched the gas but i have NOTHING holding my rear batteries down and at the time i didnt have the 1/2 thick rubber paddles under my front and rear battery to prevent them from sliding and the battery slid all the way to the tailgate and yanked the power wire from my 3sixty.2. I went to push the batteries back in place and put the power to the 3sixty.2 but dumbass me never turned off the radio and as soon as the processor got power all i heard was a loud pop and all the amps were in protect. I thought for sure i fried the speakers or amps but they were fine after i powered off and back on my radio.

If your amp is not 100% secure just check for loose power or speaker wires and any rca's being loose. Thats where i would start.
