Powering 2 subs

I own a Marantz 8802a and love it!

However I also just recently upgraded all my amps and speakers including 2 subwoofers. Question is I have two sub pre outs but I can only get one to go active.is there a setting I'm overlooking? I'm set up for a 7.2.4



Set “Speaker Config.” - “Subwoofer” in the menu from “1 spkr” to “2 spkrs.

When you run Audyssey it should discover both subs and reports number of subwoofer as 2. 

I owe you big. I absolutely skipped over that and it was right in front of me.

Thanks again!!

Kind regards
