I need a small audio amp circuit that can drive some small 5-10 watt
speakres, something like in a clock radio would work well. I want to hook it
up to my iPod for portable speakers. The audio output on the ipod is pretty
loud for headphones but not quite enough for speakers.

I would like to keep this as simple as possible and as cheap as possible. I
had thought about buying a small set of computer speakers from big lots for
$10 and hooking them up to batteries.

A set of powered computer speakers is probably your easiest solution. All
the construction work has been done for you, you couldn't but all the parts
as cheaply as you could buy the speaker set, and it wouldn't look as nice.
In addition, you get to choose the power that suits your taste. Be aware
that the power output specs on those speaker sets are grossly exaggerated.
If the box says the speakers put out 50 watts, mentally divide that spec by
10 to get the approximate power output. Even then, it's just a wild
approximation. Point being, the physical size of the speakers is probably a
better indication of the sound level you'll get from the speakers than the
power spec on the box.

Cheers!!!

Yes, go for the computer speakers.

Try and get the ones that switch themselves off when there is no input to
save batteries.

What you want can be bought at your local 5&dime. small speakers and
amp for walkman/cd player etc...
Usually can be had for around 5 bucks or so. Some are even one piece
that simply jack into the device.(runs on 2 AA's or one 9v.)
I have a set somewhere in a box that are more like the deluxe model,
two small speakers much like computer speakers with a double ended
mini headphone jack cable.(even has volume controls.)
They run off 9v batteries, one in each speaker.
Try Wal-mart, if too expensive go down the scale to your local family
dollar store etc...

Some computer speakers have battery housing just for what you want as
well....

wow... I've never seen one of those. What exactly does it look like. Just a
small box with a place to plug in speakers?

That would work. I have a cheap set of computer speakers that run
internaly on 12 volts, so it took nothing beyond a set of wires to
hook up a Gel Cell to run them.

An alternative is to take a old Boom Box with a broken CD or Cassette
Drive and change the cable that feeds the selector switch so that
the position for the bad sub-unit is fed, instead, by a jack.
Or for an iPod, take out the broken CD drive and put the cradle for
the iPod under the lid.
