Solder to Speaker or mobo?

[psp339]

I'm tryin to do the direct connection sound mod and I'm wondering if I should solder the wires to the speaker or the mobo.
Which one is + and - of the speaker?

mobo just solder on the edge like nico did its the best way you dont want to mess with the contact things on the speakers you can try it and if you break speaker I got 2 slim speakers for ya

And which contact point is positive?

Um well for me cuz i wired 4 leds to the speakers, it is hard to solder the  wires onto the back of speakers and make the speaker fit. So i just soldered to the front of the speaker, there is two holes.

I don't think it matters. But I may be wrong.

NVM figured it out and now I'm done! First time doing a sound mod in a PSP Slim. Video coming soon.
