I just got a 2019 2.0AT 25000 miles. The whole left side of my car sounded way quieter than the right so I bought new speaker and replaced them with good after market and still same issue I have messed with the balance meter and all and nothing works does anyone have any idea what else I could try

 

No idea what the problem might be, but you can find out more from the car with built-in diagnostics.

1. Turn the car to "on" (with brake not pressed, press the POWER button used to start the car.) You could also got to ACCESSORY (press power button again) or just start the car. Some diagnostics only work in specific modes.
2. On the center display, press-and-hold HOME, SOURCE, and AUDIO POWER. Hold until the diagnostic menu comes up.
3. Choose the "Detail Information and Setting" half of the screen.
4. Choose AUDIO CHECK.
   1. This lets you cycle thru playing a tone on each speaker. It also displays, and lets you reset, the current volume setting for that speaker.

There are many other diagnostics you can try here, and there are help pages for them.
