I'm in a two piece (drums and bass guitar) and to get a louder, meatier, harder sound i've decided to start using sansamp rbi preamp with a Crown XLS 602 Power Amp (http://www.crownaudio.com/amp_htm/xls.htm). The cabs i'm gonna use are an ampeg svt 410he 500 watts 8 ohm and a Marshall MBC 115 300 watt at 4 ohm. Becuase both cabs are different ohm ratings i was going to run the power amp in stereo seeing as the sanamp has two out puts. So would i be right in thinking that this would work? Also, are there any warning signs i should watch out for? I notice that the ampputs out much more than what the speakers are rated at, will this damage them?! Also, if i'm using both out puts on the power amp should i have it set to stereo on the back?
