Regarding Home Audio. If A Speaker Is 150 Watts But My Amp Gives 30 Watts Per Speaker. Will It Still Sound OK
Speaker ratings like those you have described are maxmimum ratings, not minimal power requirements. What you want to know is your decibel, or db, sensitivity rating on the speakers. The higher the sensitivity, the less power you need from your amplifier to power them. You actually don't use most of the amplifier's power anyway. The higher the wattage output of the amp the greater headroom you have before the amplifier reaches the clipping stage, where the amp starts to distort its sound. If you have a good quality amp, 30 watts is more than enough to power your speakers to a high enough volume to make you happy.
There should also be a minimum wattage rating for the speaker. As long as you are above that and below the max 150 watts, you should be OK.

This watt rating can be very misleading.
150 Watts can be RMS (Continous Level) or Peak (Max)
30 watts RMS = about 75 watts Peak
50 watts RMS = about 150 watts Reak
You need to fid a speaker that is rated for a 30 watt amp. Most will tell you the min and max amp rating.

im no expert but id say u need to find a better set of speakers for the amp for better quality

I would ignore the ratings and find out what the speaker sensitivity rating is. This will tell you roughly how loud it will go.
For each 3db of gain, you double the power.
Let’s say that your speaker is rated at 90 db 1 watt/1meter. At approximately 3 feet, 1 watt will produce 90 db. 2 watts will produce 93, 4 produces 96, 8 produces 99, 16 produces 102, 32 produces 105. Then, you are essentially all done. 105 will be loud, but not earth-shaking loud. Plus you probably listen a little further than 3 feet.
However, none of this matters if you like the speaker. And, by the way, 150 watts is probably wishful thinking with a lot of speakers. If you put a sine wave at 150 watts into most speakers at 20 Hz, you will have a woofer cone imbedded in your face or in the wall behind you.

The absolute truth is too LITTLE power destroys speakers…Actually turning any amp over two thirds gain will start to damage speakers…If your speakers aren’t loud enough at 2/3 volume, get a bigger amp.

yea it will be fine
