    Well, over the years I converted three practice amps into heads and was left with three 8-inch speakers and I had the idea of putting them all into a cab, problem is one of them is 4 Ohm and the other two are 8 Ohm.

    Is there anyway I can hook those three up together with no trouble?

    Two 8 ohm speakers in parallel = 4 ohms; then hook that pair up in series with the 4 ohm speaker = 8 ohms.

    Yes.

    Wire the two 8ohm speakers in parallel for 4 ohms. Then wire the single in series with the parallel pair for 4 + 4 = 8 ohms.

    Beware that the three speakers may be different efficiency, one may be louder than the others even though they will all get equal energy.

    what speaker impedance does your amp require? 8 ohms (as described above) is almost always good. But you should check to be certain.

    Well, here's the head that I'm building around the Chassis of a Vester Maniac amp.

    It's not done yet, I have to sand the cab, the top isn't connected yet and there's more details I have to get right before assembling it.

    You could wire up the speakers as noted above and try them out before you build a cabinet.
