newbie subwoofer questions

[Erman_94]

i am ready to pull the trigger on an ED A2-300 sub any day now. this will be my first real sub (my other came in a HTIB). i just had a couple questions so i can get rolling as quick as possible:

1) do subwoofers (and the a2-300 specifically) take regular speaker wire? or is there a special cable/wire needed for subs?

if so, what cable should i be looking for? are they expensive? (i want a HIGH quality one...but have no idea of the cost)

2) is the volume for the sub separate than the volume for my speakers? (i.e. would i be able to turn it up/down from the remote like my speakers or no?)

3) is there anything else a pure sub/speaker newbie should be aware of?

thanks guys.
