Sound volume

TL;Dr: is there a way to increase Bluetooth volume max using a third party app or is there a way using the settings other than turning off “reduce loud sounds” and “change EQ to Late Night”.

I recently made the switch from Android to Apple, and I’m rather disappointed because the max Bluetooth volume is a lot more quiet on my new IPhone compared to my old Android, I’m using a TaoTronics TT-BR05 Bluetooth receiver to connect wirelessly to my car’s speaker system, and I can’t get the max out of my speakers because of the limit on my iPhone.
