Hi everyone,

Just got a couple of quick questions for those who are "in the know" regarding audio.

Basically I'm trying to make my own battery powered iPod speaker system (not necessarily "portable", but able to operate without a mains power source). I'm taking a 3.5mm output (from iPod, phone, etc) and outputting it to two speakers similar to these. My plan is to set this up on my campsite for when I go away, that way I can have a decent sounding speaker system (unlike those little portable ones you can buy).

So far when I connect the iPod directly to the two speakers using one of these the sound quality is good except the volume isn't quite where I want it to be, which is expected as there is no amp and the iPod is designed to power little ear buds.

So here comes my question, what could I put between my iPod output and the speakers to give it a decent boost in volume, while still maintaining quality? Obviously I'll need to add a power source such as a 6v, 9v or 12v battery to power the amp(s).

I've been looking at some of these single channel amps here. Would I be able to simply connect two of these to a battery and then connect the speakers directly to the amps? What sort of performance could I expect from these $25 amps?

Would a 9v battery give me much play time or would I need a car sized battery?

Thanks in advance!
