Thx. I did exactly that.
1 - Put amp to Stereo mode (DONE)
2 - Plug BOSS to Channel A using pos +1 and neg -1 terminal on Speak ON.
3 - Plug Sub to Channel B using pos +2 and neg -2.
Doing so makes the BOSS work but SUB is silent. Please note that I'm using SpeakOn connector. On the sub side, I wire it exactly the same (Pos +2, neg -2). Also, on amp, I have CrossOver set to FullRange. Not that it will make any difference but thought I should mention this.
Update: I finally got it working (thx to notnyt). I had to use the following
1 - BOSS on ch A with pos +1, nev -1
2 - Subon ch B with pos +1, nev -1
1 - BOSS on ch A with pos 2+, nev 2-
2 - Subon ch B with pos 2+, nev 2-
3 - Mode: Stereo
Ignore what it says behind the panel. the only combination that worked is what I have in this post. This allowed me to independently handle each output.
