Hello

I've been experiencing a weird audio distortion issue when using Bluetooth to stream music from my phone to my head unit. The sound is fine when connected via USB or AUX; but once I switch to Bluetooth, there's a noticeable crackling sound; especially during high-volume tracks or bass-heavy music. It’s not the speakers themselves because they work perfectly on other sources.

I’ve already tried unpairing and repairing my phone, checking the Bluetooth settings & ensuring my head unit’s firmware is up to date, but the distortion persists. I also tried a different phone and it didn’t solve the issue. Is this a known problem with Bluetooth connectivity in car audio systems, or could it be something related to interference, head unit settings, or wiring? I have checked https://www.tsikot.com/forums/car-audio-video-systems-153-cyber security guide for reference .

Any tips or advice on troubleshooting this would be appreciated. I’d love to get this fixed without having to resort to using a wired connection. Thanks in advance!


Thank you !
