Well in the monsoon wiring diagrams it shows outputs from the HU labled as:
"Right Rear Speaker Output (-)"
"Right Rear Low Level Audio Signal (-)"
"Right Rear Speaker Output (+)"
"Right Rear Low Level Audio Signal (+)"
And then it has the same for Left

Would I be correct in assuming that the Right/Left Low Levels go into the amp and go out to the sub?

You can't really tell which HU outputs are going to the subs because it splits off in the Monsoon amp. Check the thread at Amp Hook-Up To Existing Monsoon System for pictures of the wiring diagram for the Monsoon system. They are on the next to last post on that page.
