I have a M8200 with a cab. I think it's about a 2000 or 99 year model. The speakers have never been replaced. I tried to remove the speakers today but cant get the screws to come out. They just spin and spin. I looked it up and it says its because there is a nut of the back side of the headliner that has come loose. Is there anyway to get these out without removing the top of the cab?
Need help with replacing speakers

sounds like the 'engineer' that designed it, needs to come over and show you how HE can remove them !
Would need to see pictures or drawings to see IF you could make a 'backside' tool to help you.

What you can try in this case is pulling up the speaker while turning the screws, so that the nut gets some friction against the panel. But this will only work if the nut was put in without any threadlocker.
He did not ask that question, did he?
I would put rivet nuts into the holes. I am actually surprised that they used nuts for holding the speakers, this would not be common practise in industry.
Is it possible that they are plastic rivets pushed it? I've seen them with a philips head for the centre pin to get out. They turn very quickly without coming out. In this case you have to stop the rivet from turning.
That's what I was wondering, Hugo. Probably not for speakers, though, but it should be checked out.
I've often used a small pry bar to put some pressure on something, as you suggested in post #3.
If that doesn't work, there's always C4.
Another option would be to grind off the head of the screw using a Dremel if it's recessed, or a Fein Multitool (or similar) with the appropriate blade if the head of the screw is exposed.
I agree with @Hugo Habicht re nutserts or rivet nuts or whatever you want to call them, assuming the material is strong enough to support them. They're hard to beat in sheet metal. I bought a nut rivet tool years ago and when you need it, you need it.

In most cases if the screws are not corroded the top is not too awfully hard to remove.
Pretty drastic measures, but yes, this will remove the speaker.If that doesn't work, there's always C4.
Make sure you sign up for KTAC first though ...
