    It needs three cabs to get the full 435+ watts out of it. Since the 810 is split into two chambers, you MIGHT be able to use 2/3s of the amp's power.

    I ran mine with 2 Peavey 1820s (18 + 2 10s in each cab) plus 2 Bergantino subs. I'd say it was loud enough all right. The problem is getting 3 4 ohm loads in a smaller package. I don't know what's in the cab you mention for speakers, but you are looking at at least a rewiring job in the cab, maybe needing to put in new jacks, maybe new speakers to get 3 4 ohm loads out of it. I've read the amp can be run with less that 3 4 ohm loads at less power, but also read that the amp will explode and take most of the galaxy with it if you use anything other than 3 4 ohm loads. There seems to be as much superstition as information about the amp.

    I never ran mine with less than the 3 loads. I'm in the process of modifying an Ampeg Isovent cabinet to run at 2 4 ohm loads, so that small cab plus another small cab will be 3. It's a ridiculously powerful amp, but challenging to own. There's some info here,


    and also on the Yahoo group. I came across one guy wanting to sell his after putting $1000 and a year of waiting into it just to get it set up. Not for the faint of heart.
