Amp not getting proper voltage

Amp worked great for about half the day.. Maybe played it for an hour tops.. Went to start my car this morning and now it's back to reading 6.4 volts..

Pics of what you're doing will help us help you. Pics of you're grounding point...

Pics of my first ground are in the first post, I can get pics a little later. I added the ground to a location where another ground from the factory is located.

Guessing the amp has an intermittent short in the power supply.

Vibration rattles it back and forth from a failing state to working and back.

Assuming that's what is wrong with it, what would cause an the power supply to short?

Shorted PSU or output FETs, maybe....

Although FETs usually fail pretty hard and not intermittent but hard to say without digging around.

Have you popped the cover yet (unpowered)?

Yep, didn't find any noticeable signs of damage.. I'm almost debating running 1/0 from front to back power and ground and seeing if that fixes my issues.. I'd assume it would? I get my repaired sae-1000d back in a few weeks Nd don't wanna fuck that up for the second time
