Check out this Volvo Tweeter Modification
The modification I performed on the stock dash tweeters would apply for the other speakers in the Volvo that have a tweeter with a (electrolytic) capacitor as a high-pass filter. This is also very commonly found on coaxial speakers (such as my old Infinity 5012i set), and this modification would also apply to those as well.
This modification results in better treble response as well as improved clarity from the tweeters. The method of performing this modification is removing the dash tweeter, cutting out the old capacitor and replacing it with a film-based capacitor which is by far a lot better (more linear) than the Bi-Polar capacitor that was used on the tweeter.

Hi, thank you for this tip. indeed, sound is much clearer in my tweeters.
Just for eventual readers of this subject (blogged on FCP): back D pillar tweeters on V70 or 850 estates are 4.7 uF, not 3.3 like front ones.
You will need 2 of this one : MKS2B044701K00JSSD
Front one IE number: MKS2B043301H00KSSD
easy job!
