Passive Sub Woofer connections ??


Hi

My 3rd system has a passive sub.

The NHT sub has a pair of right/left channels.....in/out.(8 speaker terminals)

No provission for coax.

Question:

Should I go 4-wires from my amp to my sub, then 4-wires from the sub to the speakers.

OR

4-direct wires from my amp to my apeakers, and 4-direct wires from my amp to my sub(sharing the speaker terminals on my amp with both the speakers and sub)

Thanks

In case A, there's the possibility of a HP filter being inserted to remove the low bass from the main speakers. In case B, that possibility doesn't exist. The user's manual should say so.
