i have 2 old 6ohm speaker from a condamn hi fi set, now, how do i create a amplifier circuit for that speaker? if possible i want a USB powered amplifier circuit ..any idea guys ?new here, thanks
search around and get http://www.techlib.com/electronics/audioamps.html#computer
can this amplifier give an equal quality like VS4121 altec lansing spaker?

Such a project (amp powered from USB) may be possible if the speakers are very high efficiency (USB cannot deliver much power). For sure not a beginner's project, sorry.
If USB is not strictly necessary, you have many choices 😉
Have fun, Hannes

Sorry, but it's a bit absurd - USB gives you 5V and 500 mA - that's hardly enough for decent headamp...

If you want a good answer to your question you have to be more specific:
- what will it be used for?
- what power do you need?
- what is you budget for this project?
- what kind of amp you want, class A, AB, gainclone, tube, solid state...?
The more details you give, the better answer you'll get 😉
Judging from your speaker's description I think gainclones will fit the bill and that's in another section of this forum...
i know nothing about amp, can you give me any guide how to determine what i want?
well, just to power a normal desktop speaker, 2 small desktop speaker.

Use multiple USB port in parallel, say 20 ports give you 10A of current at 5V, then boost up to whatever voltage you desire.......but what is the purpose?
