Hello, it has probably been a while since you did this, but I just recently discovered it and plans to do the same thing to my edge sport. I have managed to take off the 8 screws on the subwoofer, however, I still can’t get the middle part out of the subwoofer box. It seems like there is some sort of adhesive. Is this normal? Was it easy for you to get it out? Hopefully you’ll reply, thanks in advance.
