Assuming you're feeding signal to amp via speaker-level outputs from head unit (?), you don't need it (by virtue of "signal sensing turn-on" via speaker-level inputs). It's not clear to me that this amp has signal-sensing turn-on via RCA inputs. If it were ever mentioned, I don't recall which amp inputs you'll be using.
