Mini amp

Hello

I have 4 speakers:
1 watt
8 ohms
1,5" diameter

And now i want to make guitar or/and bass mini amp,that
would work on batteries(9v,12v,or couple more of them,i dont mind)
I have a little cabinet where i can fit it all,i just need schematic for amplifier
if someone has one.

Thanks

The 22 Caliber has got a class-D amplifier chip in it. The chip used doesn't even come in a non surface-mount version.

Heres two simpler options

That would work great. Really it doesn't matter to much with a solid state amp, as long as you have a load on it, it's happy.
