Stereo Guru's, help me pick my amp

I will be installing four speakers into my YJ this coming weekend. The front pair are rated at 75 watts RMS each (4 ohms) and the rear pair are rated at 60 watts RMS each (2 ohms).

First question: am I going to damage anything by having speakers rated at different resistance?

I am trying to determine the amplifier that will meet my needs without blowing the speakers. Currently I am looking at this. It is rated for 50 watts per channel at 4 ohms (90 at 2 ohms). Will this mean my front pair will be under powered and my rear pair will be destroyed? Or will this amplifier work as long as I don't crank it to 11?

you should be fine, the front and back have their own gain setting. the channels are separate from each other.

Is it a potential issue that the rear speakers RMS are lower than the amplifiers? Their peak is far higher...

Never use the peak rating. Use the rms power.
