Ok. If I run my Peavey DPC 1400, into my 8 Ohm Genz Benz, and in the second channel run a 4 Ohm cab, will this be a problem? How about if I chain the cabs? I'm guessing people buy 2 x 8 Ohm cabs for a reason... I've never chained my cabs, never needed to, until recently where gigs require more stage volume.
