In my 95 NAS 90 I just went to Best Buy and purchased something on closeout. From what I recall they were Pioneer 6.5 in and cost about $50. I would go out and chaeck except its in the shop right now
Changed the back two too. I'm in SoCal so we don't get much weather here but I never have my windows on and I know the people that wash my 90 have to get them wet.
They fit in really snug and took only 30 mint to get them all the door. So for $50 I wouldn't worry too much if they get ruined.
Oh yea they sound good too, and I dont have any problems hearing them when Im driving 70 on the highway.
