Does anyone know the stock speaker wattage?

[SalsaVibe2003]

I just installed a new Alpine head unit in my 03 Vibe. Everything is working, save the popping noise that is heard whenever i change tracks and the fact that the volume at 5 is the loudest i would go. I know that line level converters would solve the second issue, but i was toying with the idea of an aftermarket amplifier. So i was wondering if anyone knew the wattage of the stock speakers, in case there was any possibility that i could get away without replacing them. Thanks guys!
