Quite late but no one else has taken it...

Have a look at the man page for the exact details but this shouldd help:
mplayer -af volume[=<v>[:<sc>]]
his will add an audio filter that   
   
                <v>
                      Sets the desired gain in dB for  all  channels  
in  the
                      stream  from  -200dB  to  +60dB, where -200dB 
mutes the
                      sound completely and +60dB equals a gain of  1000  
(de-
                      fault: 0).
                 <sc>
                      Turns  soft  clipping on (1) or off (0).  
Soft-clipping
                      can make the sound more smooth if very high volume 
lev-
                      els  are used.  Enable this option if the dynamic 
range
                      of the loudspeakers is very low.
                      WARNING: This feature creates distortion and 
should  be
                      considered a last resort.
