No youl end up blowing up the speakers.
What you need to be looking for is RMS power level.
The amp outputs 150 watts RMS, but the speakers only accept 30 watts RMS, so basically when u turn the amp past 30 watts, ul blow the speakers.
Your speakers should ideally be rated higher than what ur gonna put into them, to cover yourself i.e 150W amp, get 200w speakers.
Only ever look at the RMS value as well, PMPO or peak values dont mean a thing, all they are is the max level a speaker can peak too, it dosnt mean the speaker will stay at that level constantly which it would be if u had it cranked up.
Hope this helped a bit!
