I would think that it would use the same template as QNEW, but have never experimented to see if that is the case.
I believe you can put a /t switch in the target string and then specify a template file path/name after the switch.
The /ld switch tells AutoCAD to load the AecBase.dbx file, which is the one file that needs to be loaded to make ACA, ACA (or AMEP, AMEP), rather than just AutoCAD.
