Moin, Before I get stoned: I have already used the SuFu, but this did not answer all my questions on this topic. I have a S70 T5 EZ. 97. For a T5 the equipment is quite low. It is not the original radio installed, probably no one was ordered, but the Clarion CRN 25. It only comes sound from the dashboard and the front doors. The speakers still work, but sound rather dull and snoring even when the music I don’t hear anything from the hat rack. Now my questions: – Has anyone had any experience with retrofit speakers? I’ve already seen some of JBL, Blaupunkt, Pioneer, etc. with matching adapter online. – Are there always cables attached to the speakers, or can they be easily retrofitted? – Where would you get original new speakers? Except from Volvo or Sandix. Thank you.
