The C70 has a much different amp to a sedan/wagon. I don't know if it has a separate Dolby unit or if it is integrated. I am assuming you have a center speaker on the dash? There was a thread recently on problems with a 'regular amp' that someone had just fitted. It was dirty/bad connections that were the issue on the cables. As you know the amp is in the trunk on LHS behind a panel. Check it's connectors too.

Yeah, i had the amp out a few months ago when detailing the trunk area and installing new bulbs and tail light housing and I cleaned all the connections before installing it back but i will trace the pro-logic wire to find it and clean all connectors.I assume electronic cleaner or isopropyl is sufficient.

Contact cleaner is best as it does not leave a filmy residue like IPA does.

Volvo’s are judgy. They won’t play any music by a Madonna, the BeeGees, or Supertramp.

Classical will always work, as well as anything by Prince.

Bach organ music in the S70, awesome
