how i remove a boom bass, in a mixed song

You may not be able to remove it completely, but using an eq, find teh frequency it is, and reduce that. It will take all things down in that frequency though.
 
Don't know exactly what you're talking about but the ugly "woofy" kind of stuff usually resides around 250 on your eq.
 
Depending on the particular issue, I find you can use use a roll-off eq for everything below 40 or 50 Hz without much ill-effects.

Sometimes my mixes have bass problems when played back on systems with sub-woofers. This is because my studio monitors don't really reproduce well in the very low frequencies. A roll-off generally cures it.
