so im in a metalcore band, right now we have not been having good luck with setting up live. the gear we use is a peavey 4 channel pa with two 12in speakers and two 10in monitors. Our rhythm player uses a peavey 100 watt half stack, lead player uses a randall 120 watt half stack and i the bass(best) player uses a gallien krueger full stack. and acourse our drummer. the problem we are having is that we can't hear each other live and dont have enough inputs to monitor guitars. can anyone give us a good way to set this equipment up so we could hear each other good.
