I've gotten bad parts from autozone out of the box, have them test it (assuming install was done correctly )

If you have a ammeter, you could check for stray current pull

If it drives then dies over night I would suspect something is shorted causing current draw all the time

I sanded and scraped all the stock ground under the hood. It was pretty bad. That seems to have stopped the flickering. Resting at 12.95

I installed a volt meter too.

Idle voltage is 13.6~

is this normal? This was after a full 2a charge from the charger.

I also removed the door bulbs and did an led swap for the 2 dome/map and rear handle locations.

When did you replace the battery? If it was before the alternator install and the alt failed it would have severely drained the battery. It could just be that the battery wasn't sufficiently recharged. Cleaning the grounds was probably a good idea. If you're at 13.8v and 12.95 resting you shouldn't be having any problems. If the 12.95 was just a surface charge immediately after shutting off the car you need to wait for a while or turn the headlights on for 20 seconds or so to remove any surface charge and get a "real" resting voltage.
