2003 mondeo 2.0 TDCI. Ive changed the battery and the radio is super quiet. Ive tested the speakers and they all work using to 3&6 buttons to test and they work perfect on the test.

Ive inputted the correct code and the radio is finding channels and playing CDs doing what its suppose to do exept its mega quiet.

The balance, fade, treble bass etc... are all set right aswell

any ideas?
