Speakers chirping

I have owned my 2015 prerunner for a year, when it started to get to the hotter months of the year this chirping sound had appeared, it starts chirping 5 minutes after starting the truck sometimes sooner when it is hot outside, I’ve checked grounds, wires, fuses, nothing seems out of order or burnt up, when it does work for the short period of time everything sounds great, everything is stock except the tweeters which I replaced thinking that was the problem, would this be a HU problem at this point?

 

Mine does that too but it's like always happening until I turn my head unit on, owner manual chalks it up to having something to do with your phone being too near the speakers

 

Does yours do it on every input even the radio?

 

I have an old taco so my only point of failure would be my pioneer head unit.
