I was wondering if that was how to do it.
@brylandgoodman I’ve been thinking of doing the same thing with two amps in mono and adding another sub. Only thing, most Rel subs incorporate a single neutrik connection and cable ends for positive, negative and neutral in a high level format. I think I remember a Rel video somewhat explaining this, but think this connection option was for using Rel pairs with a single amp? Hoping this would still apply -and still be safe- for monos using Rels.
From Rel blog: “If connecting 2 RELs, connect the black wire of each REL to a negative speaker terminal of the corresponding channel; twist together the red and yellow wires of each REL separately and connect each pair to the positive speaker terminal of the corresponding amplifier channel.”
Did Rel never give a clear answer when contacted? I might reach out to them as well as I’ve also been quite vexed by this.
