New owner radio problems

I know that there is a lot of radio problems with the Tacoma. I have read a whole lot of post on about them but I haven’t came across one like mine. I’m sorry if it’s common or known about highly.

I bought the truck and it came with an aftermarket radio in it and a factory radio in the back seat. In the morning the radio works fine. It quits different points of the day. Thought it was the aftermarket radio, switched the radios now the stock one is in it. It is the JLB with sub woofer. The stock radio system is doing the same. I noticed the volume would not show the level on the screen and the tuner button when you push it won’t let you adjust the sound. So would that be the JLB amp?
