Hard to tell for sure - that's a small pic, but if they are what I think they are it seems the official name is "snap plug", but I've called them bullet connectors and people seem to know what I'm talking about.
Thanks, Im tryin to put my Alpines in my box but I need to strip the box wires and add the right connectors (Snap Pugs)...which I should be able to get at a Radioshack...right?
