my system consist of

Maranzt 5400
Nad C320BEE
Wharfedale Diamond 9.1
RCA QED Silver Spiral
Cables QED silver anniversarry bi-wire

I like almost everything about the system and now am planning to upgrade a subwoofer and I've read fantastic review of the wharfedale SW150, I listen mostly to slow jazz and medium low volumn but I seem to find the lower end missing even at this low volumn. The question

How do I connect the sub to my amp? can I use the pre-out from the amp hook it to the line level input and loop back from the line level output from the sub to the amp?
Will doing this when I cut the frequency level say at 50Hz nothing beyond this goes to the diamond 9.1 and ONLY handle by the sub?
Will it in anyway affect the clarity I'm currently enjoying when I put out a long RCA looping. (I'll be using 2 pairs 2meter QED Qunex2)

Thank you and hope you can advise me soonest as I should be shopping for a subwoofer this weekend.
