actually you should only use 330 uf but 50 vdc other then that you'll be ok !
as far as the speaker in concern the one you picked on ebay will work just solder your yellow and white wires where the red and black wires are already located!
make sure you do not solder the wires and they stick out and ground out on the metal of the speaker as that will blow the board and or audio amplifier on the ps 2 board!
