Just following up as promised ... better late rather than never! Seems the harness issues are sorted out, but here's what I learned from 2ADDICTS on the missing bass issue (reduced signal strength vs out-of-phase front speaker):

So, I assume the 15W AMP loss from the missing ASD module isn't as significant as the out-of-phase issue with the harness wiring. I'd say order a harness and enjoy.

I think it's a combination of both. The out-of-phase condition that the original wiring in the harness created in the subs had a far larger effect than any lost line-level input voltage that taking ASD out of the signal path creates. And honestly, that amount of power (15W) is nowhere near enough to make a tremendous difference in bass frequency SPL. It would be manifested far more in the higher audible registers than in bass.
I too contacted TechnicPnP and asked whether or not all new orders are being filled with updated harnesses and received the following response from Elias:

"ASD Bypass harness is completely fixed of schematic problems. Full bass restored. 👍"
