So I’ve installed the ilx650 in my truck. All after market. Amp for the components up front and amp for sub. I’ve got gains adjusted to where they need to be and everything setup through the twk 88.

Now for the problem. Hands free calling on my iPhone is very low. I have the volume for calls all way up. Volume on phone all way up. Music via Bluetooth or car play is good and normal it’s just the hands free is very low.

The deck is updated to the latest firmware from the website. I’ve emailed alpine support and after a week they replied saying it’s probably the gain on the amps. But like I said music screams.

Anyone else had problems with hands free calling on alpine decks.
