Okay so the problem is every time my car sits overnight it wont start the next day. Im sure nothing is on in the car ive checked multiple times. Every time i go to charge it, my battery already has a full charge. Before jumping it the car locks and unlocks, the lights on the dash light up and everything, it just wont start (i hear it sparking but it wont crank), i took it to autozone they did the load test and it said my starter, battery, and alternator was fine. It will only start when i have the battery charger hooked up to it or get a jump from another car. After i get it started and drive it around, it will start up the rest of the day just fine until i come home park and leave it overnight.

Sounds like there is some parasitic drain somewhere. Any aftermarket electrical components?

Probably a bad battery. Those Autozone testers suck. It needs to be tested with a load tester. If the CCA's are down by 100, that's enough to keep it from starting.

have you cleaned those battery terminals? It can be something as simple as that. Also if you have access to another battery swap it out and see if it does the same thing. As mentioned above cranking amsp might be dropping. Especially in cold weather car needs enough cranking amps to start it up.

What accessory is being powered by the black wire with the blue crimp connector on the positive terminal? I hope that's not your amp power wire since it only looks like that's about 18ga.

Unrelated note. I don't think your battery tie down is doing a lot of good with one side disconnected.
