Volume is so low on my iPhone 17 Pro Max when using Bluetooth or a dongle

Only when using the dongle or Bluetooth, the volume is crazy low. The phone’s built-in speaker itself is louder than the volume it will allow me to play via dongle or Bluetooth speakers. I’ve already tried disabling the “reduce loud audio” function. For good measure, “limit maximum volume” function is also disabled. No change. Basically if I’m driving on the highway, have the window open, or have the heat on in my car, I can’t hear my music.
