Phone call sound from headunit speaker after amp install.

[Skyliner33]

I have just installed an amplifier to a Discover Media head unit and now everything is working correctly except when I use my phone.
Instead of the sound coming from the vehicle speakers as it did before it seems to becoming from a very small (quiet) speaker in the head unit.
Is it possible I have dome something wrong or is there a setting I need to use.
Thanks.

It’s either the Bluetooth/nav sound is at minimum on the headunit or check the wiring, ie front output is going to the input in the amp

Thanks, its definitely not the sound turned down, (and its phone and nav sound). Not sure I understand what you mean with the wiring comment. Music sound plays fine so it must be wired correctly? Plus the plugs from the head unit to tha amp will only plug into one place.
