I have an old Rockford Fosgate 160x4 punch trans.ana amp. And I just purchased a P2D4-12 single subwoofer. I have a image from the 160x amp manual on how to do a mono connection, but I just want to make sure my ohm impeadance is proper for the DVC. So just to clarify I’m making sure my setup will work with a single sub in this amp. Also since it’s DVC I would have to wire it a little different than he diagram. Thank you
