if i have two speaker and each are 30 watt rms, and i want a 2channel amp to push them, can i get 50x2 at 4ohm rms amplifier, i mean will it blow up the speakers because it has 20 more watt?
Just be ginger on the volume and light on any settings. Depending on the amp it might be overrated anyway. You're not dealing with alot of power here so the quickest way to kill any speaker is with user error.
