Wire to speaker connection.

well this is my first attempt at wiring speakers and after looking at the manuals i have come up with this wiring solution . first i thught the little bridge connectors were jsut "placeholders" , lol!

okay so the question is, will this type of connection suffice? the av guy that sold me the system showed me a cable with four cables connected and said i can also use that to get some kind of better frequency, cant remember what he said as i was allready a bit confused when he started talking about cutting the lower wires shorter than the top ones.

so, any tips or suggestions are welcome.

also this is how my sub is connected, there are a few inputs, what are they? can i improve my subs sound by using the other inputs? also the phase dial on the right hand side. what does it do? when i turn it i don't really hear any difference.
