    Can it handle two 4 ohm cabs?

    No, I dont think so. Its been awhile since I had mine, but the 100 watt side can only do 8ohms and the 300 watt side can only go to 4ohms. How ever this works, the amp wont go down to 2ohms. I could be wrong. :)

    So basicaly it can handle two 8 ohm cabs at 100 watts each or one 4 ohm at 300 watts?

    The 800rb has two power amps, one stable down to 8 ohms and the other to 4. Basically you could have an 8ohm speaker (sees 100w) and a 4 ohm speaker (sees 300w). If you get 8 ohms speakers you can use it on either amp (low amp gives 200w @ 8 ohms, 300w @ 4). Two 8 ohms speakers on the low amp (300w) will give eachs speaker 150w (300/2). These amps are loud too. The design of the amp doesn't allow bridging.

    Like I said, I havent had it for awhile but it has two amps in it for either full range or bi-amp. One amp is 100 watts at 8ohms and that is its max. The other is 300 watts at 4ohms. So on this side you can use two 8 ohm cabs or one 4 ohm and get 300 watts total, and the other amp just one 8ohm cab at 100 watts. You can use this full range or bi-amped. You could use for example, a 410 @ 4ohm on the 300 watt side for the lows, crossover into a 210 8ohm @ 100watts for the highs. btw, I always ran full range. Its a nice unit.
