Errr.....repost !!
Wat i meant was the equalizer in winamp is totally independent from your windows volume control. The purpose of the equalizer is to some sort enable u to play ard wif sound frequencies....like car audio...high, mid, and low. So, usually these wares like winamp have those preset eq settings like rock, soft rock, techno, classical and etc. Since u want to have more bass...not totally forgetting abt sharpness, try using techno or rock. Anyway, do try using other setting as well to see which suits ur listening pleasure.
