Hello,
I have once opened up speakers from my old computer, and internaly they worked on 9V DC, i could therefor plug in a little 9V battery, so i was able to get a very cool
portable sound device to plug in MP3’s and that kind of stuff.
I would like to make something like that again, but a little bigger, i can use multiple Li-Po (3.7V) battery packs as power supply.
Could any one help me to picks an amplifier wich could be powered by batteries?
As an example i have a 6ohm speaker hanging around wich makes very good sound, but i could buy new ones to fit the amplifier if needed!
So the goal is to have about 2 speakers(around 100W-200W in total) to amplify music from an MP3 or similar device, powered by batteries (almost any ammount of DC power available!),
and wich can go quite loud.
Sorry for my bad english 
Thanks in advance,
Snorreman
