Need some fast help please!! RE: amplifier for my speakers

Picking up a 4 channel alpine amp (MRP-F300) for my speakers.. but i want to make sure it wont blow them.

My speakers are:

Front: Pioneer Premier TS-D802P
260 watts MAX
60 watts NOMINAL/RMS
4 OHM Nominal

Rear: Pioneer Premier TS-A832P
240 watts MAX
40 watts Nominal/RMS
4 OHM Nominal

The amp i want to get is the Alpine MRP-F300... which throws out:
50 watts RMS x 4 at 4 ohms (75 watts RMS x 4 at 2 ohms)

Soooo. what im worried about is this. I know my front speakers can handle it no prob because their rated up to 60watts RMS, im worried about the rear ones which say NOMINAL 40watts...

Will those rear speakers handle the 50w rms the alpine will dish out? Im not going to be cranking my music super loud all the time.

just turn the gains low. you can set them using a DMM and a 1khz test tone cd

I always run more power then the speaker recommends.. my tweets say 60w rms, im running them from a 80w rms amp, my mids say 60w they are on a 100w+ rms, sub says 350w i run 500w rms..
I Have yet to blow a speaker in 15 years. prevents clipping, keeps the thd and noise floor low, less stress to amp and speakers. also allows for big dynamic peaks.
Most speakers can handle much more then the RMS rating. just as long as the signal isn't clipped.

If I was going to run those speakers i would prefer 100w RMS per channel or more.
Gain and crossover settings are important.
