Portable speakers in a PS2 Controller?

Using 2x2cm and 2x4cm speakers (4speakers total) preferably with a basic crossover and 4xAAA batteries and a 3.5mm jack for input. Perhaps a volume switch too (presumably this is a simple matter of a variable resistor. I have an idea of what speakers to use... two emac speakers and two 2cm Mylar speakers from maplins. Any help on what components I need ie. amps and capacitors would be great, or pushes in the right direction at least. thanks alot Matt

Sorry about so late, been trying to do well at university.
@themike That link looks really useful, cheers, the ones I had looked at were all complete boards I was thinking I was going to have to do some serious re-routing of parts.
I'll be sure to have a good crack at it over the summer.

you could propably use some mini air speakers, they throw out more sound then regular speakers, but finding a small and powerful amplifier is the tricky part

You're not gonna get too powerful of speakers in the 2cm variety, so you don't need a whole lot of power. For small things like this, I'd suggest the LM386 from National Semiconductor. I've used these in headphone amplifiers and small amplifier projects and am happy with their performance. Read through their datasheet (http://www.national.com/ds/LM/LM386.pdf); they have a lot of simple suggested circuits which can be easily modified for your needs.
