The stock door speakers are actually 5" speakers. Almost nobody makes these anymore, last pair I saw was in Crutchfield and were Polks, but that was 2+ years ago.

6.5" will fit in the front doors, 5.25" in the rear. The big problem is mounting depth of the speakers, especially in the rear doors.

Some aftermarket (high quality) speakers have larger magnets, and these may not clear the stock cutout in the sheet metal on the rear doors. I have a set of 5.25" Infinity Kappa (green cone) that were in my last 91 744 in the front doors (fit with alot of room to spare), tried putting in the rear and they wouldn't fit. I'm probably going to have to trim the opening a bit.


I bought 2 pairs of 6.5" Blaupunkt speaker for my little brother. He has a 95 Saturn. While these aren't the best speaker in the world, they're better than your stock ones and/or most offerings I've seen at chain stores...especially for this price ($9.99/pair!, 2 pair for 30$ with shipping!). Even better, these are shallow speakers and will probably fit the rear doors of the 740. I'll try one and see, but I'm pretty sure it will.

I assume your speakers are the same as mine, 92 740 since my 90 760 and 95 940 are the same as well. The front speakers are a strange size they are not 5.25 or 6.5 somewhere in between. However, 5.25's are the best fit for the fronts as well as the rear. The rear door speakers are actually 5.25. The problem with aftermarket speakers is they usaully run too deep. I had to purchase 2 sets of speakers and neither fit right. Try pioneer speakers PIONEER TS-G1347 5.25" 2-Way Speakers they have a shallow mounting depth and should work. I am trying to get those right now (see my post earlier on radiator hose). The pioneer's are less than 2 inches which is the depth of the original speakers.

Simply drill the rivets out. Hold the drill at various angles to keep the rivets from spinning. To re-mount, it's best to use a pop-rivetter (with washers if needed), but sheet metal screws or tiny stove bolts will do in a pinch.
