I was at the junkyard today just browsing.
However I scored a S90 front lip (project snowplow begins this summer) and then I saw a fairly complete 98 C70.
Interior was mostly intact apart from the dash cover (somebody had taken it already) and the seats, but I noticed it still had all the speakers.
Got the front tweeters and puled the rear shelf speakers thinking that they might fit, but I hadn't done a lot of research.
Now after I've done some reading up, it seems like the rear Dynaudios would be a mistake and won't fit right anyways.
As for the front tweeters - one turned out to be blown, the other is working but sounds softer and quieter than the stock one. By the way, the stock tweeters were 8ohms! So it seems like the front speakers are also wired in pairs.
But anyways, should I return the rear shelf speakers, or are they worth the upgrade?
