Hello, I have 2003 XC70 with hu-603 audio system and have a pioneer mvh-a210bt radio and it has worked just fine for a year. A few months ago three of the speakers started to sound too quietly, only the front right was fine. I thougt it could be a amplifier gone bad, so I bought a new one but it...

Sorry for the duplicative thread, don’t know how I managed that. This one could be deleted.

I would like as much info as I can get in the layout, ohm ratings and sizes of the speakers in my 2018 S60 T5 Dynamic with standard stereo. Where can I look?
