Hey guys. Today was the day I completed my rack. Now I need to hook everything up. I'm using my Behringer BX3000t as a preamp for now. I was wondering if i can use the speaker output as a line out to the power amp. Also, do they sell 1/4 inch/speakon speaker cables for the power amp to the cab? thanks btw, this is what i got.
