As an alternative solution to opening up the amp and adding relays to get rid of the turnoff thump I'm looking at putting a relay on the speaker outputs.
If the speaker outputs have a common ground I could use a single relay.
I got out my DVM to check but I can't tell what's what with the hard to access Speakon contacts, and the subs are buried in walls so it's hard to check at that end.
Schematic starts on p.3 here if that helps (it's over my head):
