compatability confusion for newbie, yamaha ca-1010

i am setting up a new system, purchased mint ca-1010, rated at 90 watts into 8 ohms, almost double into four etc. i am looking at powering paradigm titans 8 ohms 80 watts, and a passive svs sub 4 ohms 350 watts with it. it has a coupling switch on the back. on or off. i don't understand ohms. is there a swtch or something that determines what the amp puts out4 or 8 or is it the speakers themsevles that determine what they need and take it? will this setup work?

I don't know too much about these things, but you normally wouldn't need a switch for one pair of speakers...the amp reacts to the load.

I think your amp is fine with the pair of Paradigms, but I don't think it's enough to power the passive sub along with them. You will probably need a seperate amp to power it (or at least I'm fairly sure you will. Maybe someone else knows more??), or buy a powered sub.
Yes, exactly. I had a powered sub that also acted as the crossover, so the signal went from speakers. You can also check on the active sub w/crossover option if the seperate amp & crossover gets too price for the passive sub.
