Your speakers all have an impedance of 4 ohms. If you want to run them in parallel with each other you will put the amplifier into a 2 ohm load.
If you are running 2 pairs of speakers from a 4 channel amp, then they would be running at 4 ohms. The power in your amp is fine for the speakers.
If you want to run your speakers on half of your amp at a 2 ohm load (110w x 2) and the other half (220w x 1) to a sub, that would be better because your Infinity speakers are going to be kinda bright and will want a sub to counterbalance things.
