The ones in my '90 were something like 3.5" all around. The reason I say this is I replaced them with 3.5" Infinity Ref Series.I did this as the 3.5" fit right into the Blose boxes with little modifications. Most people though choose larger speakers, and then it's a little more work.I also added a sub as without it, the low freq's just aren't there.As much as Bose isn't the hottest to me anyway, got to hand it to their engineering to get that much bass out of such a small speaker and enclosure.As you likely know, each speaker has it's own amp, and the Bose speakers are a completely different ohm spec that aftermarket speakers, so once you change the speakers, you may as well change the head unit as the Bose amps won't drive any other speaker to any degree.You can reuse the existing wiring to connect your head unit to, to go to the 4 speakers if you get a little creative at each end, not rocket science.
