Is there a simple audio amplifier circuit I can use with an 8 Ohm speaker??

Is there a simple audio amplifier circuit I can use with an 8 Ohm speaker? If you know of any, or have any, could you please post a link in your answer? Thanks!

Also, I'm not very good at reading circuit diagrams, so if its easy to read, bonus points!

Google "lm386".  You'll get hundreds of links detailing amps build with this chip.  It'll give you .5 -1 watt into 8 ohms.  It's cheap, less that $2.  Radio shack stocks it if you are near one.  Only takes about 5 parts to make an amp.  Some of the links are to tutorial sites and they will be very specific in detailing the build.  Good luck.

Here's an 'ible for reading schematics.

Also schematic tutor.

It's really just learning the symbols and following the wires.

When building, make an extra copy and mark off the parts as you place them and trace off the wires as you wire them.  That way if anything ain't colored you might have missed it.

Study some and come back here with questions.  There are lots of people who really know what they are talking about with this stuff.  I just know enough to think of a good search word and use google.

Good luck and watch out for cold solder joints.

I found them! Thanks a lot! But I still can't read them >.< I know that seems stupid, considering how simple the circuits are, any Ibles' that help with reading circuit schematics?
