Simple amp for a complete newbie
Hi folks!
I recently bought two very cheap speakers that i would like to hook up with my computer. Commercial amplifiers are a bit too expensive, so i wonder if it is possible to construct one myself. The only things i really need are a volume control, two RCA or one trs jack, and some kind of connector for the speakers.
(Correct me if im wrong)
It would be nice if someone could give me instructions for this. :)

These are the specifications from the back side of the speakers:

Impedance: 4 ohm
Max continous power handling capacity: 20 W
Max music handling: 30 W
Sensitivity: 1,2 W

If you want cheap and simple, go with a chip amp of some kind.

Two LM1875 chips would be ideal.

I think you are should be looking for a chip-amp

be even then, you can get a NAD3020 for 150 dollar: ..DIY is fun, but not cheaper...

LM675T,a very good choice for the beginners.

It was a cheaper solution i was looking for, so i'll just buy one then. Thanks for the advice anyway :)
