Single cd system to monsoon system install questions

[UNOMYFLO]

"It also appears at each speaker there are two connectors, one for Monsoon, one for non-Monsoon."

2 connectors from the harness?
Or 2 sets inputs on the speakers themselves?

why would they do the 2 sets on the speakers? wouldnt they just have 2 molex plugs in the doors?

perhaps the ohm's change when using the sub?
this is why the dual speaker inputs at the speaker itself?

thnx Doug
