Hey everyone.
This is my second time here, first time only as a guest (To see a friends post lol)
Just before last year we shifted, and now our new renovations are nearly completed and it's almost time to set the home theatre up.
Last tiem I was a slacker and didn't do anything. In fact when it came to packing up and moving all I did was plug everything out and shove them in bubblewrap and into a box, didn't even bother remembering what plugs went where. Silly me :(

Now I opened them up to see them and test my knowledge, and I now need to know a lot of things.

First of all, what is the difference between Current and Voltage source? do I simply plug the speakers via a component cable into either of these?

Secondly, as it is a 10 year old (BUt sitll pretty good *cough*) hoem theatre, there's a receiver (Sunfire calls it 'Grand Processor') and then theres an amp, how would I go about routing it?
Based on my knowledge, it is speakers --> voltage/current source on amp, then mic leads from the amp into the receiver. Is this right?

Third(ly lol) What the hell is Seven Axis? It's a 'section' next to Audio Outputs (for bypassing the amp I think) and it is labled 'Sides' and has component audio (Or is it aux) red and white component inputs.

And a few other questions:
Is it normal for speakers to not have power inputs? I've only opened up our centre speakers and there are only component inputs. My friend tells me power is supplied through the amp (Dont know how it gets there... but is it true?)
What's the point in additional 'Audio Out' outputs on the receiver? I mean... wtf I want the home theatre mostly for the sound
My receiver only has outputs for 'Sub 2 and Sub3'. It's clearly a 5.1 receiver. So where did Sub1 go and wtf is 2 and 3 doing here?

I'm pretty noob at this, I thought I'd understand this better... guess I'm not that 'geek' ive always been called :(

let me know if you want photos of the back of the amp & processor - took some for my friend and they're still on my mac :) (<-- yes my mac is working perfectly fine... sorta)
