MF M1Clic - Adding Velodyne sub

Hi all,

Hope you are well. I am not an audiophile but an audio enthusiast. Would appreciate your guidance on a query below. To date I have assembled a system based on my ears (listening taste) but going forward need help on the technical side. I was considering adding the the Velodyne digital drive plus 10 inch powered sub to my existing audio set up. Please could you help me on how should i set this up. My current set up is as follows -
-Dynaudio Excite x36 (2 passive tower speakers) (http://dedicatedaudio.com/inc/sdetail/4705/21139),
-Musical Fidelity M1 Clic as preamp and source (http://www.musicalfidelity.com/m1clic/)
-Musical Fidelity M1 Pwr (powered amp in mono mode for driving speakers - bridged speakers) (http://www.musicalfidelity.com/m1pwr/)
-Atlas and wireworld power cables & accessories

As you can see from the above, i am trying to add a sub to a setup that is predominantly set up for stereo system (2.0). The amplifier and the preamp do not have dedicated line outs for a sub. I need to be creative here and get the best of the system. Please could you answer my queries below.
a) Please note i have chosen the sub based on my room dimensions and reviews, if you think i should add a different model please let me know
b) Is the setup optimal given the music equipment; i.e. do i need to add receiver or speaker splitter box
c) The sub has several inputs/outputs, please could you help me assist on the best way to leverage the sub capabilities
----Should i chain sub and speakers
----I was hoping to use RCA splitters at the M1 clic (preamp)
d) Could i add the Wii connect system to get some flexibility
e) Given my speakers what levels should i set up my crossover and volume
f) Any other consideration that I need to understand

Thanks a lot in advance. Please drop some web links to the items / connectors / splitter boxes that I may need to buy off amazon or your vendor references.
