Making an mp3 speaker system

Question

I have 2 8 ohm 10watt speakers that im trying to use to make a speaker system for my mp3 player. I hooked the mp3 player up to the speakers but it wasn't quite loud enough, its also going through a filter capacitor first. what do i need to use to amplify the signal coming from the mp3 player? Or is there another way to do it?
