20w amplifier with old 150w speakers??

I have two old Technics SB-S407 speakers that say INPUT: 150w on the back and I'm trying to set them up so I can play off a computer in a coffee shop. Can I use a 20w Lepai Tripath TA2020 Class-T Hi-Fi Audio Amplifier to play audio from the computer through the speakers, or do I need more power?

Hook it up and give it a try.

It maybe all you need...or want. It won't hurt.

The definitive answer . . .

Speaker rating in watts is how much power they can handle. By your description they can handle "UP TO" 150 watts. This means that they will surely handle the 20 watt input of your amp.

More power? How loud do you need it to be. More power = louder. Then again, a good amp will deliver cleaner sound so high power is not needed.

Clear?
