Thanks everyone for the quick responses.
I was worried because I read a thread a while ago about some dude using regular screws on a Stereo Integrity subwoofer with, what I assume, is the same deal with the surround. SI recommends using, if I remember correctly, a screw with some kind of washer I think. I can't remember exactly.
I'll just pre drill a hole through the surround, and mount them. If you guys say it shouldn't be an issue, I'm good with that.
I did take some pictures, if anyone's curious
