Hi, very nice setup! I picked up a set of Mc501's today!; I'm running 802's also. I have a question about how you managed to hook up your REL STIII series sub to your monoblock amps. I too have a REL STIII sub, but I'm afraid to hook it up as some have damaged thier equipment. Ive been getting conflicting ideas of how to connect the three wires to the (Nuetrik) "high level" speak'on connector. Since your's is together and working and identical to mine, I would like to hook up mine the exact same way. The wires are red, yellow, and black. Where on the monoblocks does each individual wire go? This would be a tremendous help. Best reguards, and happy new year!
