05 Corolla LE having weird heavy/stall issue.

Hi everybody, I have a 2005 Toyota Corolla LE. She has 111k on her.
I bought her back in July so not long ago and she ran great. She had 94k when I bought her so I've done a lot of driving but I always keep up on maintenance. So here it goes, im going to make this as simple as I can without leaving any info out.
CURRENT ISSUE:
1. Car feels really heavy when driving. (while at freeway speeds and holding the gas pedal down, if you let off the gas the heavy feeling will be very strong)
2. If car is at idle and I turn the air on the car will start to stall.
3. When coming to a red light itll sometimes start to stall and this little alternator meter reader I have plugged in will show the alternator losing charge
Backstory: So about a month I noticed when my stereo system was playing at night that my lights would flicker dim. So I stopped playing my music. A week after that I started to notice the car would randomly feel like it would get heavy here and there while driving and when stopping at a light the cars idle would go up to 1100k then down to 400k and be rough like it was about to stall then it would go back up and repeat until Id start going again.
Another week or so after that I realized that when I turned the air in the car off and all electronics then the idle would be fine. So I thought it is prob the alternator going out because I had my Subwoofers playing alot without a farad capacitor and it prob made it work overtime or something. So I hooked up a multimeter to the battery and it read 14 something but when I would turn the air on it would quickly drop to a 12.4 or so then back up and on a chrisfix video he said if it dropped below a 13 when doing that test then the alternator was going out. So I bought a new alternator and im not so sure it did much. The battery reads at 12.5 when the car is off and the belt is new. So im left with this annoying issue. The car starts fine and as long as no electronic accessory is on it will go to idle normally but once I start going it feels really heavy and bogged down. I have a Battery/Alternator tester I bought from Harbor Freight. Its the black one that plugs into the cig outlet and it'll read my battery as good and my alternator as good then when I either turn any electric on the alternator yellow light which is normal will go away and if I put the air on high then the red light goes away and then I turn the air off so I dont stall or damage anything. Also sometimes when I come to a red light it'll feels like its going to stall and the alternator meter lights will start going out.
SO far since owning the car I have done:
Oil Changes
Transmission fluid /filter change
Spark plug change
I kept thinking maybe it a air intake leak or maybe a fuel issue but why would a brand new alternator show signs of not charging when air is turned on? and I assume the heavy feeling issue is related. Oh and the car has no codes on a obd scan

No mention of the check engine light here. Has it come on?
Even if it hasn't you should have the computer scanned for any stored codes.

Last line said scanned? Have it scanned again by some other device.
With all that seems like the entire power of the engine (heavy feel?) is going to run a stereo system ("Sub-Woofer?") whatever that set up is.
Just noted in all that voltage dropped below that 13v line with engine running either overloaded alternator or engine RPM couldn't keep up and should with loads wasn't expecting that much.
By "air" you mean A/C I take it? That's another heavy load on an engine.
IMO it just can't adjust to tolerate excessive loads.
In there you also notice lights went dim with items running? If car was running proves it if not DON'T DO THAT it's not meant to power things for more than moments with engine off,

(Tried to fix words so not all run on? This site's software just does that?)

Yeah, I missed that line about the codes.
I find it very strange to have all these engine performance issues and no codes.

no by air I mean just the blower motor. or the heater I guess. Also when I bought the car in july non of these problems existed. I was able to run the A/C (I mean A/C) and play the stereo (my stereo has 1 12" subwoofer and a 300w amp) pretty small setup. it ran everything just fine.
