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.
Thanks guys. I harness is now on the way.
