In my discussion “amplifier” is a ‘box’ that accepts a small signal and it’s output drives a speaker. It really doesn’t matter what is inside the ‘box’.
As long as the circuit inside the box is perfect, that's true. The perfect box WILL deliver the same voltage at any current. Those are the amps that output 50 watts into 8 ohms and 100 watts into 4 ohms. Many many amps won't output double the power into 4 ohms that they do into 8 ohms.
If one applies a voltage to a speaker, current will flow. If the voltage is high enough too much current will flow and the speaker will cook.
Again, this is true of a perfect amplifier. Not all amps will do this.
But what about OP's original question, anyway?By the way, OP should use those speakers and that amp. It will work. He should never turn the volume up far enough to make the amplifier clip. He should think about (and then experiment with) the speakers in the environment he wants to use them in (outdoors) to be sure that they output enough sound to play loudly enough.
