2 REL Strata Subs and Mono amps

Hi all. Need a quick bit of advice.
Running 2 REL Strata IIi subs, each connected to its' own mono bloc amp.
Runnung Merlin TSM's.
What is the correct way to wire the REL high level cable with neutric connector?

The REL cable has a red, yellow and black wire.
Do BOTH the red and yellow wires get connected to the RED speaker output on the amp, with the black wired to the Black connectors on the amp?

Thanks
