I do realize that the v128 is a 12 inch speaker, not a 10 inch.  But I couldn't find a good 16 ohm, 10 inch speaker that I liked the sound of, the price, and people said it wasn't suited too well for metal anyways.  The amp head (that little practice amp I have), is a solid state, not a tube.  Anyways, about the size of the speaker.  It doesn't matter to me if it's a 4x12, as long as it sounds good.  I do still need someones help for the wiring problem.  How do I get four 8ohm speakers wired to be 4 ohms as the total in the end?

You can't wire four 8 ohm speakers to make 4 ohms. Like Dave says, you need 4 ohm (in series-parallel) or 16 ohm (in parallel) units.
