Oh for the love of pete....
I just built a '14 Durango the way we originally wanted
Limited AWD V6
Second Row Console
Safety, Security, Convenience Group
Trailer Tow Package
and the site did NOT require me to add the optional amp/subwoofer group that WAS required with the SSCG at the time we ordered.
I hope for my sanity that the site is wrong and that they didn't change the requirement because I'm paying to have that subwoofer cargo bin swapped out....
