Good program to raise volume of speakers ?

It seems that my old ibm speakers doesnt really seems to have a loud volume with my new system (look at my sig) , and also the it doesnt have a volume adjuster :( , and also when i watch most movies like avi , the volume sounds so low when i put it to the max :(. So i was wondering if anyone knew of a good program/software which would help to increase the volume of the speakers , please ?

1. videolan (free) boosts sound by 150%
2.Matrix mixer (free: found in search google "edskes" - klcodecpack- boosts sound enough to destroy your speakers)
enjoy

Thats cool , man, thanks. I'll try those 2 apps.
