Any ideas on how to connect REL sub high level connections to 2 monobloc amplifiers high level outputs?
REL website appears to indicate that this is not possible.
My amps are not “D” class.
TIA

Simple. Connect from the positive outputs to your L and R input then connect the common/ground connection to one of the negative outputs.
The fact that the monoblocks will be commoned up by whatever preamp connections you have means you only need one ground connection.

So, to clarify, I have one amp powering left speaker it has a positive and negative speaker output, ditto for right speaker.
Connect positive of left and right amps to appropriate positive speakon terminals, and negative speaker from either to speakon negative terminal.
This is the same as normal integrated amp? Or is the earth/common referred to as some amp case earth?
Why do REL say not to do this as it can damage either sub or amp(s).
I am more than comfortable with Alan’s response, just need to understand why REL state it’s an issue.

I think they are covering the class D scenario, some if not most will be BTL, that Bridge Tied Load, so the Negative output isn't earth.
Connecting the Neg could damage the amp. What are the amps anyway? Are they set as 'Bridged' in which case don't connect the Neg, connect the common to signal ground/common.
