Homemade Speakers for PSP

I am trying to make a speaker from a an some what old stereo so I can use it for my PSP. It was working when I took it apart. This guy on this other forum makes it look so easy. http://politicalstage.com/forum/viewtopic.php?pid=243

Here is my situation: \/

Take the Red and Green/blue wire and connect them to the Black wire's by tieying them up together, Than use some rubber tape, to stick the 2 cords back together, than plug the thing into your psp and walla. I would suggest a Speakers like for the PC. or something. I've done this before lol, easy as pie.

 

But the green and wires are too small. I tried to strip them too.

 

Ok problem solved, I borrowed my neighbor's solder iron, and it works, the only problem is i can't higher the volume, so its pretty low.

 

The only problem is volume, its not loud at all, but when i put my volume on low on my computer speakers and plug the homemade one in the headphone plug it plays loud. So hopefully i can resolve this issue.

 

You would need a small amplifier, the psp minijack out dosent have 1/3 enuff power to drive that.

 

And where can I get that, and how much would it cost?

 

I still can't figure out how much a small amplifier would cost.

 

Better just get a new pair of speaker's. If you look here, it's not very expensive
