I do not know what the AntiMode cable is, so I can only comment on the use of a standard Y-cable or one with series resistors in it. The issue is whether your two output sets are independent, each with its own buffer/driver circuitry. In general, they are not in most preamps. In fact, the two sets are usually wired from a common buffer/driver with the equivalent of internal Y-cables.
If this is so with your preamp, then attaching a standard Y-cable between the two you use for the subs/antimode will also shunt together the two main outputs you connect to your amps. The result is that everything(!) is mono. That is why there are Y-cables with resistors in them. They serve to provide a mono signal for whatever use while still maintaining (almost all) separation between the channels on the main chassis.
