Really low audio sound via bluetooth

[TheDonJ77]

Don't know if this has been asked and answered before but I am having an issue with sound quality via bluetooth on the P3XL. When usuing bluetooth in a vehicle, sound starts off loud and bassy then quality just drops off and sound weak and puny. On my wife's iPhone no issue and on other Android's that I tried out no issue. Is this a known Pixel only issue and are there any helpful ideas that I can do to FIX the issue. Thanks
