Refresh Sierra Bose vs pre-refresh

[Rockyah86]

Just picked up at4x and was wondering if there's anything different with the refresh amp vs older models. I'm planning on installing aftermarket subwoofer from old truck and I have the anc delete cable and harness that plugs into Bose amp for signal. I believe it says 2014 and up but just want to make sure before I remove rear seat. I had a 2018 Silverado with Bose but the new truck has more speakers. 12 in the new one. I only count 11. Is there a sub in console like the 2018?
