No bass when using iPhone 13 through Bluetooth on car stereo

No bass through speakers In car ONLY when I connect Bluetooth through my iPhone 13 pro


bass works through every other way in car and even works with a android phone.


also volume slightly goes down and back up probably every 30 seconds. ( like I’m getting a notification, but am not)

and only sometimes I will notice music won’t play out of all the speakers when connected to Bluetooth through my phone.


I’ve tried everything I feel like. Please help

iPhone 13 Pro, iOS 18

Check your EQ settings for Music. While you can check the speaker settings as well, but since you are not hearing in all speakers in the vehicle while connected to Bluetooth, if you use the regular radio, do all the speakers work? To check EQ, go to Settings>Music. To check the speakers, go to Settings>Accessibility>Audio & Visual, you can see the balance there, make sure it is in the middle. You can also check Mono Audio there. It would be turned off for stereo, but you can try turning it on and trying music to see if it makes a difference in the speakers you say you cannot hear out of.
