I’m looking for a simple diagram on how to connect a single REL sub’s high level input to the monoblocks mentioned in the title with REL’s cable, as REL recommends using low level input for a single sub if using monoblocks.

Thanks.

REL has many nice diagrams and instructions on their website.  
Or perhaps you wish a PS Audio person gives you instructions based on what they feel is best.

One subwoofer is a job half done though. Some people would say 1/6 done.

There is a reason REL says to use low level for that type of system as there is no “simple” way to connect one sub to two amps especially ones that don’t have a true ground.
