'88 245, '99 S70, and eventually will do '92 965. Running new speaker wire. Had the rear door panel and B-pillar trim off the S70 last weekend, and the space in the bellows is really tight. However, the way that thing is wired, I'd have to take a lot more apart than the doors if I want to use a 4-ohm speaker without just running new wires(that model has 8-ohm speakers in parallel sets, so redoing with 4-ohms is not just plug-n-play). Main concern at present is getting the new wires pulled through without damaging the insulation on the numerous wires already crammed in there, or poking a hole in the bellows.
