    What Ohm rating are the internal speakers?

    Is this a Stereo amp?. If so You would need a stereo cab, or rewire one with left and right jacks, 2 speakers each jack. But if you don't have enough jacks on your amp for all the speakers, you'd have to have 2 y cables to hook them up in stereo..now here's the biggie, you'd have to be concerned about impedence of the speakers..you do not want less than 8 ohms each side or you eventially will roast the ouput chips.

    I would run it as is, as just a combo amp, or into a stereo cab alone. One big pain in the ass to do what you're asking with that amp, and you really wouldn't gain as much as you'd think.

    If its the speakers in the cab you like you could swap them with the combo speakers, but be sure your load is 8 ohms or greater.

    I looked this amp up, not much on it online. I found a pic on eBay of one. It's got two speaker output jacks, but it seems they have each speaker wired separately to each jack. You'd have to rewire the speaker wires so they both ran off of one speaker output jack. Then you'd probably need two 8 ohm speakers internal to the cab wired in series for a 16 ohm load on one output jack. Then you could hook up a 16 ohm 4x12 to the other jack.
