My b5r runs at - 200 RMS poweroutput at 8 ohms - 350 RMS poweroutput at 4 ohms - 500 RMS poweroutput at 2 ohms and it's got two 1/4 jacks to connecting cabs and a speakon output jack. I connect it with a BSE 410 Hlf with 400 watts at 4 ohms. First question : When i connect them with a single 1/4 jack what is the power ? Second question : Can i connect them with 2 1/4 jack ? If i can, what is the power ? I'm thinking of buying a second cab a BSE 115 with 200 watts at 8 ohms. Third question : Is it possible to connect this amp with this 2 cabs together to have 500 watts (at 2 ohms). Thanks. And if it's not clear ask info.
