those are the speakers I want to be amplifying along with 1 or 2 10's. http://www.cardomain.com/item/INFREF6000CS

this is the amp i'm looking at.http://www.cardomain.com/item/MTXTA3404 Now it says it gives out 50 rms x4 channels @ 4 ohms. fine. my speakers say they put out 90 rms at an impedence of 4 ohms. I also want to connect two 10's. Will this amp adequetly power all these items or not? I've heard this amp puts out 100rms x 4 @ 2 ohms. Does this have any bearing on my 4 ohm speakers?
