I have a QSC RMX 2450 for my subs. What does this mean? I have dual inputs, 1/4'' and XLR. I have a single RCA coming out of my reciever (old piece of junk, upgrading to outlaw 950 and parasound amp shortly) and don't know how to wire this thing! I have yet to find a single cable that will go from Rca to dual XLR male or 1/4 male. Actually I havnet found a cable that will go into the female either. I know that splitting this will resolve in a 6db signal loss, so would it be better to split right before the amp or right at the reicever? There is about 5 feet between the two. I need some help here guys, got this awsome amp and two tempests and NO SIGNAL!
