Yep... That's why there's a dual pattern on the basket (frame).

You can make 6.5" speakers work, but you have to do some work to do it (or buy an adapter). Or you can simply buy 6.75" speakers and slap them in.

I'm running 6.75 in Memphis Coaxials all around, and they fit perfectly w/ no clearance/mounting issues. Sound good for a coax speaker too.

Most GM vehicles are 6.75", NOT 6.5". The speaker itself may be the same size, but the opening/mounting is different.

"Back in the day" when I first got my new 94Z there was that 6.5" and 6.5"S crap (for "Special"). However, recently I think they have dropped the 6.5S size and just make the 6.5" speakers fit all the holes. When I bought some speakers for my 94Z a few months back I asked the kid at Best Buy about the S size and he looked at me funny and said, "Nah, these will work" and handed me regular 6.5" speakers. I thought I was going to have to do the "slide it to one side" trick to mount it but much to my surprise, they fit perfectly and I was able to find a combination of holes that lined up perfectly with the factory holes.

So, I bought a set of Fosgate 6.5" speakers and also Kenwood 6.5" speakers and they both fit with holes aligned in the 4th gens. Seems strange but I came to the conclusion they dumped the "S" size and now just make all 6.5" speakers with the proper mounting ring to fit both the older 6.5" and 6.5"S sizes.
