Truck has to keep getting jumped

[PUN15H3R89]

I have a 16 silverado and when i let it sit a couple days over the weekend monday morning im jumping it off? Brand new battery, good alternator, good starter, and good battery cable. I dont know what else i can check. Any help?

It is in the software my guess. The bcm shuts off circuits as battery goes low.
Have to ask have you had all recalls done? Cables and software if applies.

i do believe there is a software issue with the bcm where the child safety lock control stays awake/on after the key is off and draws it dead. 

 

also it can be any number of modules causing a draw with the key off. 

 

so either unhook battery when parked overnight/days , get a battery maintainer or take it to a shop to be diag and fixed. 

 

but nothing we can really do here on the internet. it has to be diag to find out what is staying awake with key of causing a draw.

Check for a parasitic drain if you have a multimeter. Disconnect your negative cable and put your meter between the post and negative cable.. see how much amperage is being pulled and go from there.

Then you pull fuses and check individual circuits

You are some what correct there are so many circuits that draw that it will show a draw with the key off.
Pull the codes and it will show if a circuit is drawing,low/high, open, or just out of spec.

Only thing i have done to the truck is put amp and subs but they were installed about a year ago. This problem started about 2 months ago.

That's probably where I'd start

Go to the amp when truck is off and meter the remote turn on wire. See if there is voltage. A larger wattage amp pulls a lot of power it is possible it isn't turning off.
