I'm not sure what you're unsure about. Bare speaker wire (ends) is best. Plenty of threads and posts on this forum advocating for one way or the other though.
If you're unsure about "just ramming the cable in the holes and hoping for a good connection and good sound", shouldn't you feel that way even more so about the workmanship and overall end result (sound) if you did have the ends terminated?
