How do you guys unplug this connector in the rear speaker?
I try pulling it with force but it does not event move half a millimeter.

There is a tiny tab inside the connector. If I recall, from your picture it would be closest to the driver, but I could be wrong. It will be easy to see if you turn the speaker so that you can look at the top side of that blue connector. To release, a tiny screw driver will work just fine.

Hope that helps.

To answer my question. Nothing other than force is really needed.
I was able to unplug it by holding the wire with 4 fingers and putting thumb on the speaker, use thumb to push and other 4 fingers to pull the wire.

Well, yanking hard is one approach! Simpler and easier to just use some needle nose pliers and squeeze the two sides and it will slip right out. Less chance to cause damage too.
